Description

COLLABORATION SUPPORTING SYSTEM BASED ON SOAP IN WEB ENVIRONMENT AND IMPLEMENTATION METHOD THEREOF}

The present invention relates to a collaborative support system through the Internet, and more particularly, to a collaborative support method using a Simple Object Access Protocol (SOAP) for cooperative work and communication through a multi-user Internet in an internet web environment.

In recent years, the Internet has been spreading widely, and as the use of computer communication technology and the increase of computer spread, the spread of high-speed communication network has become more common, so that the Internet can be used on a regular basis in ordinary homes. The development of the world and the web has a huge impact on social life.

In this situation, as the development of web-based collaborative support system is inevitably spreading, for example, a large number of remote participants deal with the complicated process of product design and development, and various forms of documents, images, drawings, and CAD on the Internet. There is an urgent need for a basic platform that can share data and can reliably handle large-scale web communications and transactions, such as markup for editing drawings and accurate communication through videoconferencing.

Conventional technologies for this purpose, such as the object-oriented middleway Common Object Request Broker Architecture (CORBA) and Distributed Component Object Model (DCOM), etc. are used for communication between the client and the server in a distributed environment, the method using the CORBA object-oriented Based on the technology, it has the advantage of being able to build a system without being dependent on a specific environment such as different operating systems, network environments, heterogeneous data models, data types, and implementation languages, while using the Common Gateway Interface (CGI) There are problems that are caused by the problems caused as it is, there is a problem that the slow running speed and excessive cost in the communication of the Internet environment has a lot of problems to implement a collaboration system in the Internet environment.

In addition, the method using the DCOM, supports the mutual communication of various components (Component) supporting the COM (Component Object Model) on the network, if the COM occurs in a system or on a single platform, these objects are distributed on the network While there is an advantage of enabling communication with each other, there is a problem that depends on the operating system of Windows.

On the other hand, the client server system in the Internet environment as described above "client / server based application service management system and method disclosed in the Korean Patent Registration No. 066399" and "three-layer structure disclosed in Korean Patent Application No. 1999-061184 On how to implement a component in a Korean language "and" Master's Thesis, Korea Advanced Institute of Science and Technology "published in September 1997. A technology relating to client / server systems, such as the "Cova-based client / server architecture for web application integration" disclosed in, is disclosed. However, the "client / server based application service management system and method" merely relates to a Java-based application service management client and an application service management information transmission protocol, and merely discloses a structure using an applet or an application of the Java language. "How to Implement Components in a Three-tiered Architecture" refers to the architecture of using CORBA and DCOM as a client / server connection. In addition, only the client / server connection method using CORBA is disclosed in the "Cova-based client / server architecture for web application integration", and the problem in the client / server system using CORBA and DCOM is still not solved.

Accordingly, an object of the present invention is to provide a collaborative support method using SOAP to enable multi-user collaboration and communication through the Internet regardless of platform and language in a distributed environment. It consists of clients (Services), Service Providers and service brokers (Service Broker) that connects them, and the customer requests the service broker through the Internet to generate data and register it on the server. In this case, the service intermediary also attempts to provide the result of the work to the customer by enabling the service provider to perform the work through the Internet.

At this time, the above-described structure has an open structure of a client / server method using internet computing technology and distributed object technology on the robust communication environment of the web (World Wide Web), and the server side has an enterprise Java bean (EJB) structure. The client-side application is developed in Visual Basic under Microsoft's operating environment, so that the client program can be implemented in any language without any modification on the server-side source program. To provide.

The present invention for achieving the above object is XML that supports standard data exchange protocol between client and server, server and server, client and client regardless of language and platform in collaboration support system using SOAP communication in Internet web environment. A method for SOAP based communication, comprising: (a) establishing a communication environment between a SOAP client and a SOAP server using the XML based SOAP communication API; (b) the client generating a client class by referring to a SOAP API and serializing client data to transmit a SOAP service; (c) the server generating a SOAP server using a SOAP API, receiving a SOAP service transmitted from the client, and performing deserialization. The SOAP communication method may be implemented.

1 is a system configuration diagram for providing a SOAP-based service according to an embodiment of the present invention.

2 is a detailed block diagram of a SOAP-based collaboration support system according to an embodiment of the present invention.

3 is a flowchart illustrating operation of a SOAP-based collaboration support system according to an exemplary embodiment of the present invention.

Hereinafter, with reference to the accompanying drawings will be described in detail the operation of the preferred embodiment according to the present invention.

1 illustrates a configuration of a collaboration support system for providing a SOAP-based web service according to an embodiment of the present invention. As shown in FIG. 1, the collaboration system providing the SOAP-based web service includes a SOAP client, a SOAP server listener, a SOAP request requested from a client to a server, and a SOAP response responding to a client request from a server. It can be seen. In other words, a SOAP message derived from a client application program module is requested to the server as a SOAP Request, and a SOAP response from the server in response to the request is returned to the client module. SOAP is Microsoft's protocol for accessing objects on the Web, and since SOAP is standardized on the basis of an XML standard that enables data exchange between clients and servers regardless of language and platform, SOAP is a multi-computer, architecture It can communicate between languages, languages, and operating systems. SOAP also enables the creation of new application classes, called web services, that provide services in a standard way, allowing application developers to create new applications for multiple systems, including collaborative support systems composed of services from a variety of web sources. .

More specifically, it is a SOAP Envelop format that defines the external form of the XML content of a SOAP message, a set of optional encoding rules that define how language types are mapped to XML in the SOAP message, followed by a function call in the SOAP message. It is an optional Remote Procedure Call (RPC) format that defines how it is expressed, and finally, the HTTP binding that defines how SOAP messages are exchanged over HTTP falls within the scope listed above. It shows how to develop a collaborative support system and defines a systematic scenario to implement a collaborative support system.

1 illustrates a flow of a typical SOAP message, wherein the server serves as a listening device 120, retrieves a request for SOAP, and an embodiment of the present invention uses one server as an example for convenience of description. For example, the listing server 120 may process a client request in association with another server for execution. In XML-speak, the SOAP message 130 creates a Root element called Envelope, and the root node has a Header element, and consists of a Body element inside the root node. Typically, each of these elements is first put into an XML Namespace, and the SOAP specification uses the Namespace Identifier to create it so that it can be placed in front of the SOAP-ENV. Requisitions are implemented to enable immediate identification of SOAP elements in things such as methods and data content.

2 illustrates a configuration of a SOAP-based collaboration support system according to an exemplary embodiment of the present invention, and illustrates a method for implementing a framework of a SOAP-EJB-based collaboration support system. Referring to FIG. 2, the SOAP-based collaboration support system includes a SOAP client 210, a web server 220, an application SOAP server 230, a data server 250, and an FTP server 240. do.

As shown in FIG. 2, in order to develop a module of a SOAP-based collaboration support system, a web browser 210 and a SOAP may be developed using Java 211 or Win32 programs 212 and 213 regardless of a language and a platform. Second, develop a Web server (220) with a servlet; third, develop an application SOAP server (230) using SOAP and EJB; By developing the base wrapper (233), it develops the system to connect with the existing legacy system and provides the function to flexibly connect the whole system.

In more detail, the communication between the client 212 and the client 213 enables the XML-based SOAP data communication, and also provides an environment to enable the XML-based SOAP data communication between the client and server, server and server. In other words, in the communication between the client and the server, for example, the SOAP client-side program is Visual Basic, the operating system is MS Windows, the server-side program is composed of different operating systems and languages such as Java, and the operating system is Linux. First establishes a communication environment using SOAP communication, a standard data protocol, then generates a SOAP message written in the Visual Basic language with a client-side Visual Basic wrapper on the client's MS Windows operating system, and then runs the server's Linux operation. Written in the Visual Basic language on the system Create a server-side wrapper that translates the language to the Java-language environment. Then, if you want to communicate with the client-side wrapper and the server-side wrapper, the SOAP message on the client side is serialized and passed to the client-side wrapper. The client wrapper makes a request to the server-side wrapper's SOAP object, and the server-side wrapper deserializes the message from the client wrapper and responds to it so that communication between the client and server occurs. Is to convert different SOAP messages according to the environment so that client and server can communicate in different operating system environments. Next, in server-to-server communication, for example, the program on the first server side is C #, operating. The system is MS Windows, and on the other second server side In an environment where RAM is composed of different operating systems and languages such as Java, Linux, etc., a communication environment is first established using SOAP communication, which is a standard data protocol, followed by the C # language in the MS Windows operating system on the first server side. The generated SOAP message is generated as a wrapper on the first server side, and a server side wrapper is generated in the Linux operating system of the second server to convert a language written in the C # language to the Java language environment. If you want to communicate with the wrapper on the second server side, the SOAP message on the first server side is serialized and delivered to the wrapper on the first server side, and the wrapper on the first server side requests it from the SOAP object of the second server side wrapper. The second server-side wrapper responds by deserializing the message from the first server-side wrapper so that communication between the server and the server is performed. do.

FIG. 3 illustrates a processing flow in which a client part is written regardless of a platform and a language and a server part is created as an object composed of an EJB using an XML-based SOAP API in a SOAP-based collaboration support system according to an embodiment of the present invention. will be.

First, when a user requests access by sending his / her user information such as ID and password to the server, the server performs User Access Verification while proceeding with steps S301 to S303. When the user authentication is successful, it is determined whether to update the software information by using the software information provided in the current client. At this time, if the software needs to be updated, the server receives the file through the FTP server 240 and updates the client system environment information.

Subsequently, the server reads the cache information of the logged-on user and checks the changed part in step S304, and if there is changed cache data, the server proceeds to step S306 in response to the changed cache data in step S306. Send data for In operation S307 to S308, the server receives its friends and their log on status messages transmitted from the web server 230 along with the log on, and sends itself to the active user. Register with server

Subsequently, the server sends information indicating that the user has logged on to a friend currently logged on through a messenger in step S309, and then proceeds with steps S310 to S311 for a real-time conference. Schedule and register a schedule. In operation S312, the server prepares and registers a material for the real time conference, and then proceeds to step S313 to select participants to participate in the real time conference. Subsequently, the server finishes the scheduling (Schedule, materials, participants) for the real-time conference in step S314, posts the information on a BBS or a web page or informs the participants through an email, and in step S315 Invite them to the conference.

Accordingly, the invited participants are notified of the participation invitation from the server and join the corresponding real-time conference session. Then, the server proceeds to step S317 in response to the session participation of the participants in step S316. Load the materials needed for the real-time conference to the whiteboard. In operation S318, the server conducts a real-time conference through a text chat, an audio / video conference, a model view, a model markup, and the like on the whiteboard, and in step S319, recording and reporting of the real-time conference are performed. Perform reporting.

Therefore, as described above, the present invention implements a problem of communication between a client and a server in a distributed environment, which is a problem in the related art, by using a collaborative support system using SOAP. Communication can be performed smoothly.

Meanwhile, in the above description of the present invention, specific embodiments have been described, but the present invention is not limited to the above-described embodiments and the accompanying drawings, and various substitutions may be made without departing from the spirit of the present invention. Modifications and variations are apparent to those of ordinary skill in the art. Therefore, the scope of the invention should be determined by the claims rather than by the described embodiments.

As described above, the present invention provides a method for designing and implementing a system regardless of platform and language in a distributed environment. The client side develops a program regardless of the platform and implementation language, and the server side uses an EJB component. We have developed a Java server. In particular, it uses XML-based SOAP protocol for communication between EJB Java server and Windows client, and facilitates data communication between client and server, server and server, and can be applied to all other systems as well as collaboration support system. There is an advantage to this.

In addition, due to the lack of standardized data representation and communication protocols between object-based heterogeneous components using conventional software components, many solutions are platform-integrated with poor integration, and as firewalls in other solutions such as DCOM, CORBA, etc. There is an advantage that can solve the communication problems caused by the client, and in order to maintain EJB-based Java in the server of the collaborative support system, the client program is implemented based on Microsoft. There is an advantage that the source program on the client side can be developed regardless of platform and language without any modification.
