Description

201007567 VI. Description of the Invention: Technical Field of the Invention The present invention generally relates to the field of computer technology, and more particularly to a method, a feeder and a system for implementing aggregation of a desktop application and a web application. [Prior Art] In the field of information technology (ΐτ), Web technology is widely used because of its simplicity, lightness, and open standards. More and more software vendors are working on developing their Web-based applications. Web applications have a number of advantages over traditional desktop applications. For example, web applications do not require software installation and maintenance, making web applications easy for the public to use. Participating in the 'Web application style' also has its limitations. One of its main problems is that the user interface based on Hypertext Markup Language (HTML) does not support advanced user interaction. Due to this problem, desktop applications are still needed in many cases. In some cases, the end user needs to switch between the web application and the desktop application to complete his work. For example, when a user is editing his blog (BLOG), if the user wants to include /·, -=»«, , , , or a picture in the blog, then the user first needs to find some photos or pictures that are needed, Then you may need to edit it as well. To do this, the user must have a photo or photo editing software (ie, a desktop application). After that, the user also needs to upload the edited photo or image to the web application. However, for some reason, the user experience may not be so good. For example, the reasons may include: (1) the integrity of the user experience is compromised; (2) the user may have to be in a different console. Switching between; (3) Web application data and desktop application data cannot be shared; (4) Users must install the required desktop application and may need to maintain it regularly. In order to enhance the capabilities of web applications, technologies such as Java script, AJAX, ActiveX, and Applet have been widely used. For Java script/AJAX methods, the idea is to write a web application with a Java script, where Java scHpt is a scripting language for providing interactive programming features. However, there are also significant limitations to using Java scripts. For example, the first limitation is that JaVascript is executed by the translator and has poor performance; the second limitation is that Java scripts cannot be used to implement some programming logic. For the ActiveX/Applet method, it is not very widely used due to its poor compatibility. On the other hand, for different applications, users need to download different plugins (plug_in), and some of the plugin files may be large in size, so it takes a long time to download it. Therefore, in view of the above circumstances, there is an urgent need for a technology that can overcome the drawbacks of the prior art and aggregate web applications and desktop applications so that desktop applications can be used to process web applications. SUMMARY OF THE INVENTION A brief summary of the invention is provided below to provide a basic understanding of certain aspects of the invention. However, it should be understood that this summary is not an exhaustive overview of the invention. Furthermore, it is not intended to limit the scope of the invention. Its purpose is to present some concepts in a simplified form as a In order to solve the above problems in the prior art, it is an object of the present invention to provide a method for implementing aggregation of a desktop application and a web application. Another object of the present invention is to provide a web server and corresponding computer system that facilitates the aggregation of desktop applications and web applications. It is still another object of the present invention to provide a computer readable storage medium on which computer code for implementing the above method is stored or encoded, and a corresponding computer program product. In order to achieve the above object, according to an aspect of the present invention, a method for implementing aggregation of a desktop application and a web application is provided. The web application is included in a web server, and the method includes the following steps: responding Launching the desktop application 201007567 initialization program on the web server for the client user's request to use a target desktop application', and determining an appropriate corresponding host server for the user; preparing the corresponding host feeder And providing a desktop application environment, and launching the target desktop application; transmitting the corresponding host server address to the client terminal for interaction between the client and the corresponding host server - desktop application interaction; and responding to the desktop application The end of the interaction' is on the corresponding host server: Stop and exit the target desktop application. According to another aspect of the present invention, there is also provided a web server for implementing aggregation of a desktop application and a web application, the web server being capable of communicating with a client and one or more host servers. And including a web application and a desktop application service, wherein the web application responds to the request of the user end user to use a target desktop application, generates a desktop application initialization request, and responds to the end of the desktop application interaction. The desktop application exits the request; the desktop application service responds to the desktop application initialization request and launches the desktop application initialization program on the web server to determine an appropriate host server for the user to provision and serve the desktop on. The application environment 'so that the corresponding host server can launch the target desktop application' and transmit the address of the corresponding host server to the client, thereby enabling desktop application interaction between the client and the corresponding host server, and Desktop application service responds to the desktop Exit request with the program 'stop and exit the target desktop application on an appropriate host server. According to another aspect of the present invention, a computer system for aggregation of a desktop application 201007567 program and a web application is provided, including: a client terminal on which a web browser is installed; one or more host servers, each a terminal service for capturing a user interface of the host server and a control agent for launching a desktop application on the host server; the web feeding device can be fed with the user terminal and one or more hosts Communicate, 'and includes web applications and desktop application services, where the web application responds to a request by the user to use a target desktop application via a web browser to generate a desktop application initialization request' and Responding to the request of the user end user to end the desktop application, generating a desktop application exit request, the desktop application service responding to the desktop application initialization request, and launching the desktop application initialization program to determine an appropriate corresponding host server for the user, and Provision and provide a desktop application environment on it to The control agent starts the target desktop application on the corresponding host server, and the web application sends the address of the corresponding host server to the client, and starts the browser plug-in on the client to intercept the client. User input and provide it to the terminal service on the corresponding host server, and

The user interface of the corresponding host server is displayed in the web browser, and the desktop application interaction and the desktop between the client and the corresponding host server are performed through the terminal plug-in program and the terminal service on the corresponding host server. The application service responds to the desktop application exit request 'stops and exits the target desktop application on the corresponding host server. According to another aspect of the present invention, a corresponding computer readable storage 201007567 storage medium and computer program product are also provided. In the technical solution according to the present invention, by embedding the user interface (UI) of the remote desktop application into a web application (such as a web browser), the end user can use the remote desktop application to process the web application. document. This means that users can use the desktop application to edit web files in web pages. When the client user is using a web application, he can send a request to the web server e to initialize a desktop application. When the web server receives this request, it will first look for an existing server that has the requested desktop application installed. The server that has installed or is able to install the requested desktop application to provide the desktop application is hereinafter referred to as a hosting server. If such a server cannot be found, the web server will assign a new host server to the user and provide the requested operating system and the requested desktop application. After the host server is ready,

The web server copies the web file to the host server and uses the web files to start the desktop application. When the desktop application is launched, the web server will return the address of the host feeder (such as the location and apostrophe) to the client. At the same time, download or install the terminal plug-in in the same Web browser of the user terminal (the terminal plug-in can be obtained from the web server). The plug-in is immediately connected to the anchor by using the terminal address. , ^ 』 host server piracy, and the user interface of the remote desktop application is displayed in the user-side web browser. Then the user can interact with the remote desktop application through the terminal plug-in 201007567 after the user closes the desktop application In the program, these web files that are modified or changed during the interaction of the desktop application will be copied to the server. This will enable the aggregation of the web application and the desktop application. The invention has several advantages. 'The first advantage is that it provides a unified access to the desktop application and (4) the application's web control platform to the end user. The desktop application can be regarded as the part of the application - and it It is hardware-independent and independent of the operating system. It can be single-login under the control of the web application. Single Sign on, SS0) features. Also, web files can be shared between the desktop application and the web application, and all changes made by the desktop application can be quickly reflected in the lion application. Two advantages are that it simplifies the management of desktop applications. For end users, there is no need to download, install, update, and maintain desktop applications on the client side. Moreover, in most cases, some desktops should rely on The technical solution of the present invention is that the user does not need to install the desktop application locally. Because the binary code of the desktop application is executed on the host server, it is easier to control the software authentication problem. For the software vendor. There is no need to rewrite the corresponding desktop application using the Web programming model. In addition, traditional desktop applications and web applications can be integrated together, and the development cycle of desktop applications can be reduced. For system administrators, It is also easier to manage some desktop applications (4), and can collect 201007567 Chinese On the other hand, because all files and data can be stored on the web server, the risk of data loss is minimized and data backup is easier. At the same time, more powerful resources can be used (for example , the host server) to provide users with better performance. The third advantage is that the technical solution of the present invention can reduce costs by utilizing virtualization and automation technologies. Some existing technologies such as VMWare, Xen and ibm LPAR, etc. Support for server virtualization. These technologies can simulate physical server simulations as several logical servers or virtual servers. These virtual servers can share the resources of the same physical server, which can improve resource utilization and sharing. Desktop applications can be deployed on virtual servers, which can save hosting costs for service providers. On the other hand, automation techniques can also be used to provide operating systems (OS) and desktop applications, thereby helping to save deployment time and reduce human error. A detailed description of the preferred embodiment of the present invention will be made by the following description in conjunction with the accompanying drawings. These and other advantages of the invention will be more apparent. [Embodiment] The following describes the exemplary embodiments of the present invention in the accompanying drawings. However, it should be understood that many implementation-specific decisions must be made in the development of any such practical embodiment in order to achieve a developer's specific goals, such as compliance with system 201007567 and business-related constraints, etc. These restrictions may vary depending on the implementation. In addition, it should also be appreciated that while development work can be very complex and time consuming, such development work is merely a routine task for those skilled in the art having the benefit of this disclosure. It is also to be noted that, in order to avoid obscuring the present invention by unnecessary detail, only the device structure and/or processing steps closely related to the technical solution according to the present invention are shown in the drawings. Other details that are not relevant to the present invention are omitted. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments according to the present invention will be described in detail with reference to the accompanying drawings. First, referring to Fig. 1, there is shown a block diagram of a system in which a computer system in accordance with a preferred embodiment of the present invention can be applied. As shown in the first circle, according to the present invention, only a web browser is required at the client side; on the server side, a web feeder and three host servers are shown. Although only three host servers are shown in the figure, any number of host servers may be included herein. As mentioned above, the host server is the server used to provide the phase_desktop application. In the web feeder, the web application and related support components are deployed. One or more desktop applications that the user may request may have been deployed or can be deployed on the host feed towel. For general web application interaction, the client browser communicates with the web application deployed on the (four) feeder. However, when a table 12 201007567 application interaction is required, the web server assigns a corresponding host server to the user, and then the client communicates with the desktop application deployed on the host server, and on the desktop. After the application interaction is over, release the host server. The client then continues to interact with the web server. Depending on the client's need for a desktop application, the process described above may be repeated many times. Referring now to Figure 2, there is shown in greater detail the components contained in the computer system as shown in Figure j. For the sake of simplicity, in Figure 2, only one host server is shown. However, those skilled in the art will appreciate that the computer system may actually include one or more other components not shown, and often have more than one host server. As shown in Figure 2, on the client side, a Pan browser plug-in is installed in the browser 1,, which will be referred to as the terminal agent n〇 (the details about the plugin will be combined below). The process flow chart of the method is described in detail). It has two main functions: intercepting user input and sending it to the corresponding host server (host server 300 in Figure 2); displaying the user interface of the corresponding host server in browser 100. You can use things like VNC (a kind of remote control software, see for^H^jealvnc^cW for more details), Windows remote desktop, and XWindow Manager for Linux/UNIX. A variety of prior art to implement such a browser plug-in. In addition, in addition to the above techniques, the Java applet (small application) method can also be used to implement the terminal proxy. For example, in the case of using the Java applet method, when the 13 201007567 applet is initialized, as shown in Fig. 2, it will be connected to the corresponding terminal service 3 1 0 running on the host server 300. Then, you can establish a TCP connection. This applet can grab the user's keyboard and mouse events and send them to the appropriate host server 300. After the terminal service 3 1 receives the event, it will generate such an event on the host server 300 to simulate the client interaction. At the same time, the terminal service 310 captures the user interface (i.e., the screen) of the host server 300 and sends the screen image back to the client. When the terminal agent 110 receives the screen image, it draws the image within the applet. In actual applications, data transmitted between the client and the server can be encrypted for security reasons. In addition, image caching can be enabled on the user side for performance reasons, and the transmitted data can also be compressed. Figure 3 shows an exemplary web application page layout that integrates the user interface of the desktop application. At the user end through the user

After the web browser enables the remote desktop application, the web page layout of the third image is displayed on the web browser of the user terminal by means of the terminal agent 110, that is, the user interface of the remote desktop application. (m) will appear in a rectangular area of a page on the client's web browser, which is controlled by the terminal agent 110 shown in FIG. , , return to Figure 2 again. As shown in Figure 2, on the Web server 200 on the server side, Weh is in the field.

The web application 210 needs to invoke the desktop application service 23G to process the request for use of the desktop application. When the client requests to use a certain desktop application, the web application (10) will generate a desktop application initialization request by 14 201007567 to request the desktop application service 230 to prepare. As shown in FIG. 2, the desktop application service 230 mainly includes the following components: a request processor 240, a file controller 250' session manager 26, a resource manager 27, and a deployment controller 280. In addition to this, as shown in Figure 2, there is also a resource pool 400 containing one or more servers on the server side for providing the required host server, such as host server 300 (for convenience) Note that only one host server 3〇〇 is shown in the second port, but may actually include any number of host servers); and an image and software repository 5〇〇 for storing the client may request to use A variety of desktop application installation software and server images. The request processor 240 provides the following interfaces to the web application 210: (1) desktop application initialization | in the desktop application initialization request sent from the web application 210 to the desktop application service 230, the client needs to send the desktop Application version information and a list of files that need to be opened by the desktop application. In addition, the initialization request can also include file synchronization options and recovery options. In addition, the initialization request may also include web session information to enable request processor 240 to reuse the same host server for the same user. For example, here is an exemplary XML initialization request: &lt;initializereq&gt; <application name=''Photoshop" version=“7.0” 15 201007567 vendor=“Adobe''&gt; 〈file url = “/images/header.jpg Loc at ion=tt crl.ibm.com:/shared/ myproject/header.jpg "synchronization" nterval = 10s refresh=true/&gt; 〈file url=“/images/footer.jpg” lo c at ion=&lt ;tcrl.ibm. com:/share d/myproj ect/

Footer.jpg"synchronization_interval=20s refresh=false/&gt; 〈/application〉 <application name=“Word” version=“2003'' vendor=“Microsoft''&gt; 〈file url=“/docs/news.doc” Location=ucrl.ibm.com:/shared/doc/ news.doc''/&gt;

</application> <session id=“DFAWER214ASDFD', /&gt; <restore imageid=23&gt;true&lt;/restore&gt;&lt;/initializereq&gt; According to the initialization response of the desktop application service 230 for the above initialization request, the client can know whether The request is successfully processed. In addition, the host server's address can be known so that the client browser can know how to connect to the host server. For example, here is a 16 201007567 exemplary XML initialization response: &lt;;initializeresp&gt; <result value = “success” appid—i,,/” &lt;address value=«myh〇st:myport,V&gt;&lt;/initializeresp&gt; (2) Desktop application exits φ When the user has completed the pair When the desktop application is used, the web application 210 can request to quit the desktop application so that the related resources can be reclaimed. The exit request can include web session information, so that the request processor 240 knows which host server needs to be reclaimed. In addition, exit Backup options can also be included in the request so that the host can be backed up as needed The server environment. For example, here is an exemplary XML exit request: &lt;exitreq&gt; <session id=“DFAWER214ASDFD” /&gt; <backup &gt;true&lt;/backup&gt;&lt;/exitreq&gt; based on response to the exit request The web application 210 can know the result of the operation. For example, the following is an exemplary XML exit response: &lt;exitresp&gt;&lt;resultvalue=&lt;tsuccess,,&&gt;&lt;imageid=23/&gt; 17 201007567 &lt;/exitresp&gt; (3) The query query function allows the web application 21 to check the status of the current environment. For example, the following status can be checked: &gt; Available applications; &gt; The host server is running for a session. In a web application, when you need to use the desktop application light, you can first query the available desktop applications and then list them in the form of, for example, a list. Here is an example of this: 〇Adobe Photoshop 8.0 □ MS Word 2003 I] Eclipse 3.0 • For each desktop application, the following properties can be displayed for the user to choose from: application name, version Manufacturers and operating systems (〇§). The above information can be obtained from the resource manager 270 (described in detail below). In the web application 210, a list of available desktop applications can be modified based on the user's authorization and needs. When the user requests to use a certain desktop application via the web browser 100 and submits the form, the web application 21 generates a desktop application initialization request and sends it to the request processor 24. The request processor 240 first checks the session manager 26 to determine if a running host server for the current session is already present. 201007567 If it is determined that there is no such host server, it will request resource manager 210 to allocate a host server for running the requested desktop application from resource pool 4000, such as host feeder 3 Hey. After the resource allocation is completed, the request processor 240 requests the deployment controller 280 to provision and provide the host server environment and obtain the host server address, such as the IP address and nickname. The session manager 26 then saves the host server address and user session information. Finally, request processor 240 sends the host server address back to web application 210. The web application 210 sends a page including the plugin (i.e., terminal agent 11) information and the host server address to the user's browser. User Browser J 〇〇 After receiving the response, the plug-in, Terminal Agent 110, will be launched. It should be noted that the plug-in program needs to be downloaded from the web server when the client first accesses the remote desktop application through the Pan browser. And the plug-in can be stored in the web server as needed. It can also be stored anywhere else on the network accessible by the web server (for the sake of simplicity, the above process is not shown in Figure 2 as shown in Figure 4. Figure 4 is simpler. The user interaction and session copy processing of the computer system shown in FIG. 2 during desktop application initialization is shown. (1) indicates that the session token is used for web application interaction as described above. Indicates that the client requests the desktop application in the web application, and (3) indicates that the web application 21 sends the desktop application initialization request to the desktop application service. 23(4) The desktop application environment is not prepared. Program initialization 19 201007567 (the detailed processing will be described in detail below with reference to the flowchart shown in Figure 5) '(5) indicates the desktop application The service 23 responds to the application 210, (6) indicates that the web application 21 responds to the browser, and (7) indicates that the browser 1 starts the terminal agent 11 and connects to the desktop. Application 3 4. After ending the desktop application interaction as described above, the user can, for example, send a request to the web application 21, and then the web application 210 will generate a desktop application exit request and send it to the desktop application. The request processor 240 in the program service 230. If the user wants to save the host server currently assigned to him for future use, the deployment controller 280 stores the entire image of the host server in the image and software repository 500. After this, the request processor 24 calls the deployment controller 280 to clean up the target host server, for example, clearing some files generated during user use, avoiding being seen by future users, and requiring the resource manager 270 to release the host. / (Server. The above process will be described in detail below with reference to the flowchart shown in Figure 6. Return to the reference again Figure 2. The session manager 26 is used to maintain and save the user session. Upon receiving the desktop application initialization request, the request processor 240 uses the session manager 260 to check if the host server for this session already exists. If there is no such server, the session manager 260 saves the id of the session and the assigned host feeder ID. If the host server for this session already exists, then the request processor 24() The host server's IP address and nickname will be returned. 20 201007567 In resource pool 400, there may be different types of one or more feeders, such as Intel/AMD PC servers and υΝΙχ servers. Operating systems and some desktop applications may be installed in these feeders: It is possible or not to have any operating systems and desktop applications installed. In addition to the physical server, one or more virtual servers may be included in the resource pool. Resource manager 270 maintains resource pool 400 and processes resource allocation requests and resource release requests. The resource manager 27 can track and store detailed information of all servers in the resource pool 400, including, for example, the hardware type and configuration of the server, the IP address, the type of the operating system (〇s), the installation or storage in the server. The name and version information of the desktop application. Based on this detailed information, the resource manager 27 can allocate or determine the most suitable server for the resource allocation request. When a resource allocation request is received, the resource manager 270 can look up the matching server in the resource pool 400 based on the desktop application and its required OS name. If a matching server (i.e., host server) is found, the matching server is marked as "in use" and its (7) address and apostrophe are returned. If no matching server is found, the resource manager 27 selects an appropriate host server from the resource pool 4 for providing and marking it as "in use". This process described above will be described in further detail below with reference to the flowchart shown in FIG. Upon receiving the resource release request, the resource manager 27 releases the server in use and marks it as "idle". If the server in use is a virtual server rather than a real entity server, resource manager 270 will destroy the server and release the allocated resources. That is to say, the resource manager 270 can manage the physical server and the virtual server. For a physical server, the resource manager 27 manages it at a box level, which means that only one physical server is assigned to a single user each time. For a virtual server, the host platform on which the virtual server is running can be shared by different users. Each user can only use one virtual server that may only consume some of the physical server resources. The virtual feeder can be prepared in the resource pool 400 prior to resource allocation or as needed. Deployment controller 280 is an automated engine for automated installation. It automatically installs remote systems, including installation, application, women's software, software configuration, system updates, and feeder backup. The installation software is usually stored in the image and software repository 5〇0, and several existing products can be used, for example, 'IBM' for the company to provide ΑΙΧ

The Windows/Linux Director, IBM's NIM' and Redhat's kickstart for Redhat Unux implement the deployment controller 280. The main function of the file controller 250 is to make files on the web server. The file controller 250 330 communicates to maintain synchronization between the host server 300 and the host server 300. This task is achieved through the control agent 3 in the host server 300. It will be a desktop application during desktop application initialization

The modified or updated file during the application interaction is copied from the host server server 22 201007567 300 to the original location on the web server 200 or to another location. The file controller 250 can repeatedly copy all modified or updated files on the host server 300 to a temporary location on the web server 200 during desktop application initialization and during desktop application exit. This is for backup considerations to prevent files from being lost after the host server 300 may crash for some reason. Of course, in another alternative, the file controller 250 can also copy all modified or updated files directly into the original location on the web server 200 to overwrite the original file' to immediately reflect the modifications or Update. This can be set by the user as needed. In the image and software repository 500, two types of data are stored, namely: desktop application/OS installation software and server image. Installation Software Used to install the appropriate desktop application or operating system for the first time on the host server (which can be a physical or virtual server). The server image is a snapshot/backup of 4 servers. The installation software can have the following properties, software names, versions, obstructions, and installation scripts. The feeder image can have the following attributes: software list, image generation date, user ID, and hardware type. On each host server (for example, the host server 300 shown in FIG. 2), in addition to possibly having a desktop application 34, two components can be installed, that is, the final 4 service 3 1 and control Agent 3 3 〇. The terminal service 31 communicates with the terminal agent 11 to obtain user input and reproduces the input at the host server 300. In addition, it crawls the host on the host server and sends it to the terminal agent 110 on the client 201007567. In this way, users can invoke and control remote desktop applications through a web browser. Similar to the terminal agent i i 0 , the terminal service 3 10 can also be implemented using several existing technologies such as VNC, XWindows, Java applet, and the like. Control agent 330 primarily has the functions of file synchronization and application control. The control agent 330 interacts with the file controller 25 on the web server 200 to synchronize files. Control agent 330 can also monitor the user local directory on the host server and track file change events. When a file is modified or updated, it can notify the file controller 25 to replay the modified or updated file. During the desktop application initialization phase, control agent 330 needs to launch the target application and load the input file. During the desktop application exit phase, the Control Agent 33 stops and exits the desktop application in use. Here, the control agent can also be implemented with a script or a program. The functions of the above various components and the processing flow of the exemplary method for realizing the aggregation of the desktop application and the web application according to the present invention will be further described in detail below with reference to the flowcharts shown in Figs. 5 is a flow chart showing a processing procedure performed during desktop application initialization according to an embodiment of the present invention; and FIG. 6 is a diagram showing a desktop application retreating (four) according to an embodiment of the present invention. A flow chart of the execution process sub-process; and FIG. 7 shows in more detail the resource allocation and provision process S52 in the processing procedure shown in FIG. 5 according to an embodiment of the present invention. . As described above, after the web application 21 generates the desktop 24 201007567 application initialization request, as shown in FIG. 3, the program is initialized to 500. Run in the cow. The fruit side should check the session manager 260 at step S510 to confirm that the existing host server is 15 240. If the result of the determination of the step 8520 of the step flight session is that if it is determined that there is no such master server, the process proceeds to step S520, and the village resource management device 270 and the deployment controller 280 perform resource allocation. And provide (will be further explained in Figure 7 of the next person), and then process 500 to proceed to $J step S530. Otherwise, if it is determined in step S520 that the host server has been present, the process 500 proceeds directly to step S53. In step S530', the current session file (for example, the Web composition 220 in FIG. 2) is copied to the host server through the file controller 250 (for example, the host server shown in FIG. 3). ). Then, in step S540, the control agent 330 activates the desired Zhuotian Miaotian surface application 34 and the terminal service 310 in the host server 300. In step S550', the user's end face value /, % port host server IP address and nickname (if the client first accesses the remote desktop application through the Pan J installed device, then also The client returns the client plug-in program, that is, the terminal agent 110)' and ends the desktop initialization process 500. Thereafter, the user can start the terminal agent 11 at the client and start interacting with the host server of the host server. After the user has completed the desktop application interaction, he can send a request to the web application 210, and then the web application 210 issues a desktop application exit request to begin the desktop application exit process 600 as shown in FIG. 25 201007567 As shown in Fig. 6, the processor 24 is requested to check the session manager 260 at step S610 to determine whether there is a host server running in the session. Since the host server 300' is indeed allocated and run during the desktop application interaction as described above, the result of the determination in step S610 is affirmative. Therefore, the desktop application exits the process 6 to proceed to step S620; otherwise, the process 600 is ended. . At step s62, the desktop application 34 and the terminal service 310 are stopped by the control agent 330 on the host server 300, and at step S63, the desktop is communicated through the communication between the file controller 25 and the control agent 330. All modified or updated files in the application interaction process are copied to the original location on the web server 21, overwriting the original file. Then, in step S64, it is determined whether the user wants to save the image of the current host server for future use. For example, it can be implemented as follows: The web application can use the "backup application" as an option. After the user selects the option, the application sends the desktop application service (4) the desktop application exit request will carry - The parameter 'requires backup of the current application. For example, you can refer to the heart and coffee p&gt; in the &lt;exitreq&gt; message given above. (4) Ask the processor to judge this parameter. If the user is in the step of saying that the user wants to save the image of the current host server, the process 600 proceeds to step S650, and through the deployment controller 28, the entire host server image (4) image and the soft (four) library are stored. After the towel, (4) processing proceeds to step S660. Otherwise, the occupation &amp; desktop application exit process 600 directly jumps to step S660, reads, the code is like a bottle, cleans the host server through the deployment controller 280, and passes through the resource management, 270 It is released into the resource pool 400 26 201007567 'and then ends the desktop application exit processing 600 shown in Figure 6. The processing of step S520 (i.e., resource allocation and provision processing 700) shown in Fig. 5 according to the embodiment of the present invention will be further described in detail below with reference to the flowchart of Fig. 7. As shown in FIG. 7, in step S710, it is determined whether the user wishes to restore the feeder image 'and the image ID specified in the desktop application initialization request to determine whether there is an existing service in the image and software repository. Image. The image ID may refer to, for example, the <restore> field in the exemplary &lt;initializereq&gt; For example, before the user requests to launch the desktop application, the user can query the image and image ID stored in the image and software repository through the web application and input the image ID when the user requests to launch the desktop application. If the result of the determination in S710 is negative, then the process proceeds to step S720 to determine whether there is a free host server having a matching os and desktop application. If the result of the determination in step S72 is affirmative, the process 700 directly jumps to step S78. If the result of the decision in step S720 is negative, then in step S73, it is determined whether there is a free host server capable of installing the requested desktop application. If it is determined in step S730 that such an idle host server does not exist, then in step S740, an error is returned to the client, and thereby the desktop application interaction process is exited. Otherwise, if it is determined in step S73 that the host server of the space exists, then in step S75, the operating system OS is installed in the host server as needed (of course, if the OS is already installed on the host server, then This step can be skipped), then 27 201007567 installs the required desktop application on the host right server server in step S760. Then, the process proceeds to step ,, step S77〇, and the terminal agent and the control agent are installed on the host server (where the terminal agent and the control agent can be stored in, for example, an image and a software repository) (of course, if If the terminal agent and the control agent are already installed on the host server, then you can skip this step. Hyun 乂乡J is then 'in step S780', the status of the host feeder is set to "Yutian."仏 仏 1舄 in use"' Then, in step S790,

The host server's ip address _ _ +, &amp; sand, J m 祉 back to the request processor 240, so that π becomes the resource allocation and provision processing as shown in Figure 7 〇, and continue to step S530 shown in FIG. Figure 8 is an example of a method and system according to an embodiment of the present invention, wherein the order is shown from the time when the user selects a certain desktop application in the web browser until the user accesses the remote end at the user end.
