Embodiment 1 FIG.
FIG. 1 is an overall configuration diagram of a program startup system 200 and a functional block diagram of a client terminal 100 according to the present embodiment. FIG. 2 is a functional block diagram of the Web application server 110 according to the present embodiment. The overall configuration of the program activation system 200 according to the present embodiment, the functional block configuration of the client terminal 100, and the functional block configuration of the Web application server 110 will be described with reference to FIGS.

  A program activation system 200 according to the present embodiment is a system in which a Web application server 110 (server) and a plurality of client terminals 100 (client terminal 100a, client terminal 100b) communicate via a packet communication network. Although FIG. 1 shows an example in which two client terminals 100 are connected, the program startup system 200 may have more than two client terminals connected or only one connected. This embodiment can be applied regardless of how many client terminals are connected.

  The client terminal 100 (100a, 100b) includes a terminal storage device 105 (105a, 105b). Hereinafter, the subscript a is attached to the component provided in the client terminal 100a, and the subscript b is attached to the component provided in the client terminal 100b. When there is no suffix in the reference numerals, all client terminals (components) of a plurality of client terminals or some client terminals (components) are shown.

  The client terminal 100 stores an execution file of a plurality of client applications 103 (in FIG. 1, the business R client application 103r and the business S client application 103s) in the terminal storage device 105. The client application 103 is an example of an application program and application software.

  The Web application server 110 is a server having a Web function for transmitting and receiving information in a WWW (World Wide Web) system. The Web application server 110 includes a server storage device 117. In response to a request from the client terminal 100, the Web application server 110 activates and executes a Web application (Web application 118). In FIG. 1, it is assumed that the Web application server 110 starts (executes) the business P Web application 118p and the business Q Web application 118q as the Web application 118. The business P Web application 118p and the business Q Web application 118q are Web applications that can be activated by a link operation from the client terminal 100.

  Normally, when the user executes the client application 103 stored in the client terminal 100, the user clicks a shortcut of the execution file of the client application 103 to be executed on the client terminal or selects a menu from the start menu. To perform an operation for starting the client application 103 to be executed. That is, for the user, the operation for activation differs for each type of client application 103. Further, for the user, the client application 103 and the Web application 118 are also started up differently.

  In the program activation system 200 of this embodiment, regardless of whether the Web application 118 is activated or the client application 103 is activated, the user can distinguish between the Web application 118 and the client application 103 or activate the client application 103 according to the type. It is a system that can be activated by the same operation without being aware of the difference in method.

  The client terminal 100 (an example of a terminal device) communicates with the Web application server 110 via a packet communication network (for example, the Internet network). The client terminal 100 includes a Web browser 101, an information reading unit 102 (an example of a program starting unit), and a terminal storage device 105.

  The client terminal 100 and the Web application server 110 are configured to perform data communication via a packet communication network. The terminal storage device 105a of the client terminal 100a stores a business R client application 103ra and a business S client application 103sa. The terminal storage device 105b of the client terminal 100b stores a business R client application 103rb and a business S client application 103sb. That is, the business R client application 103ra and the business S client application 103sa are installed on the client terminal 100a, and the business R client application 103rb and the business S client application 103sb are installed on the client terminal 100b.

  The business R client application 103ra and the business R client application 103rb have the same type of client application (executable files of the same business R application program). However, the business R client application 103ra is installed in the client terminal 100a, and the business R client application 103rb is installed in the client terminal 100b. Since the client terminal 103 stores the client application 103 in different locations, the business R client application 103ra and the business R client application 103rb have different stored locations (locations) in the client terminal 100 in which they are stored. . For example, the business R client application 103ra is a file indicated by the full path “C: ¥ business R ¥ RR.EXE” in the client terminal 100a. Also, for example, the business R client application 103rb is a file indicated by the full path “C: ¥ HOGE ¥ business R ¥ RR.EXE” in the client terminal 100b.

  The client terminal 100 requests the Web application server 110 to display a list of application programs (also referred to as applications) that can be started using the Web browser 101. The client terminal 100 uses the Web browser 101 to send to the Web application server 110 the application names (“business P”, “business Q”, “business name”) of the Web application 118 (118p, 118q) and the client application 103 (103r, 103s). By requesting the list display HTML data 111 that displays a list of “business R” and “business S”), the application list designation screen 104 that displays a list of business application names using the received list display HTML data 111 is displayed. Display on the device. The application list designation screen 104 is a screen on which a link operation such as a user clicking with a mouse can be performed. The web browser 101 is an example of a display request transmission unit.

  The Web browser 101 designates a specific application (specific program, for example, business PWeb application 118p, business QWeb application 118q, business R client application 103r, or business S client application 103s) from a plurality of applications (an example of a plurality of programs). An application list designation screen 104 (an example of a program designation screen) that accepts an operation to be performed is displayed on the display device. For example, the Web browser 101 displays an application list designation screen 104 that displays a list of application names (an example of program identifiers) of applications that can be activated in the program activation system 200. The application list designation screen 104 is a screen for selecting a specific application by clicking (designating) an application name to be activated from a list of application names displayed by the user. The web browser 101 is an example of a screen display unit.

  When a specific application name is clicked (specified) on the displayed application list specifying screen 104 (program specifying screen), the Web browser 101 starts the application indicated by the specified specific application name (an example of a program identifier). The requested start request information is transmitted to the Web application server 110. For example, the Web browser 101 transmits activation request information including an application name (program identifier) of a specified specific application to the Web application server 110. The web browser 101 is an example of an activation request transmission unit.

  The information reading unit 102 receives activation-related information that is information for starting a specific application transmitted from the Web application server 110, and starts the specific application based on the received activation-related information. The information reading unit 102 is an example of a program starting unit. The specific application is an application to be started designated by the user on the application list designation screen 104. Details of the function of the information reading unit 102 will be described later.

  As shown in FIG. 2, the web application server 110 includes a web function execution unit 113, a screen display information storage unit 114, and an activation information database 115. The screen display information storage unit 114 and the activation information database 115 are stored in the server storage device 117 included in the Web application server 110.

  The screen display information storage unit 114 stores the above-described list display HTML data 111 in the server storage device 117. The list display HTML data 111 is used to display an application list designation screen 104 that displays a list of application names of the business PWeb application 118p, business QWeb application 118q, business R client application 103r, and business S client application 103s on the display device of the client terminal. It is data of. As shown in FIG. 1, “application P”, “application Q”, “application R”, and “application S” are listed as application names on the application list designation screen 104. The application name is an example of a program identifier that identifies application software (application program).

  The list display HTML data 111 includes URL link data for starting a general Web application 118 in association with each application name displayed in a list, and a definition described later for starting the client application 103. Link data to the file 112 is embedded (stored).

  In the list display HTML data 111, URLs for starting the respective Web applications correspond to the application names “business P” and “business Q” of the business P Web application 118 p and the business Q Web application 118 q which are Web applications 118. It is attached.

  Further, in the list display HTML data 111, the client application 103 (103r, 103r, 103) is associated with the application names “business R” and “business S” of the business R client application 103r and the business S client application 103s which are the client applications 103. 103s) is associated with the file name of the definition file 112 (112r, 112s). As shown in FIG. 2, the file name “01.SCU” of the definition file 112r is associated with “business R”, and the file name “02.SCU” of the definition file 112s is associated with “business S”. Are associated.

  The activation information database 115 stores activation related information for activating the client application 103 installed in the client terminal 100 in association with the application name of the client application 103. In the activation information database 115, activation-related information corresponding to the client application 103 is collectively stored in the definition file 112 (112r, 112s) for each type of the client application 103 (that is, for each 103r and 103s).

  In FIG. 2, the activation information database 115 stores a definition file 112r as activation related information corresponding to the business R client application 103r, and stores a definition file 112s as activation related information corresponding to the business S client application 103s. That is, the activation information database 115 stores the definition file 112 (112r, 112s) in association with each of the client applications 103 (business R client application 103r, business S client application 103s).

  The activation related information corresponding to the client application 103 is program location information indicating the location of the client application 103 in the client terminal 100 in which the client application 103 is stored. The program location information is, for example, a full path in the client terminal 100 in which the client application 103 is stored.

  For example, as shown in FIG. 1, it is assumed that the business R client application 103r is installed in two terminals, a client terminal 100a and a client terminal 100b. In this case, the program location information that is the location information of the business R client application 103r includes the full path 112ra “C: ¥ business R ¥ RR.EXE” in the client terminal 100a and the full path 112rb “C: ¥ HOGE” in the client terminal 100b. There are two full paths to “¥ Service R ¥ RR.EXE”. These two full paths 112ra and 112rb are stored in the definition file 112r indicated by the file name “01.SCU” corresponding to the application name “business R” of the business R client application 103r in the list display HTML data 111.

  That is, there are as many definition files 112 as there are arbitrary client applications 103 handled by the program activation system 200. The definition file 112 stores the full path 1121 (1121ra, 1121rb) in all client terminals (100a and 100b) in which the client application 103 (eg, 103r) corresponding to the definition file 112 (eg, 112r) is stored. ing.

  The definition file 112 is set, for example, when the system administrator or the like inputs manually or automatically from the input device of the Web application server 110 when the system of the program activation system 200 is set. In addition, for example, the definition file 112 is input to the Web by the Web browser 101 (an example of the program activation information transmission unit) of the client terminal 100 when the user inputs the full path 1121 (an example of the program activation information) from the input device of the client terminal 100. It is set by being uploaded to the application server 110. For example, when the user installs the client application 103 in the client terminal 100, the full path 1121 (program activation information) is automatically uploaded to the web application server 110 by the web browser 101 (an example of a program activation information transmission unit). It is good.

  The web function execution unit 113 executes various general web functions. The Web function execution unit 113 includes a display information transmission unit 1131 and an activation information transmission unit 1132.

  When the display information transmission unit 1131 receives a display request (an example of a display request signal) for the application list designation screen 104 transmitted from the Web browser 101 (display request transmission unit) of the client terminal 100, the display information transmission unit 1131 responds to the display request. Then, list display HTML data 111 (screen display information) for displaying the application list designation screen 104 is transmitted to the client terminal 100.

  The activation information transmission unit 1132 receives activation request information for requesting activation of a specific client application 103 transmitted from the Web browser 101 (activation request transmission unit) of the client terminal 100, and an application included in the received activation request information The definition file 112 (activation related information) corresponding to the name is extracted from the activation information database 115 by the processing device, and the extracted definition file 112 is transmitted to the client terminal 100.

  5, 6 and 7 are flowcharts showing the flow of the program activation method (communication method) of the program activation system 200 (communication system) in the present embodiment. A program activation method (communication method) of the program activation system 200 (communication system) will be described with reference to FIGS.

  In the program activation method of the program activation system 200, a terminal program installed in the client terminal 100, which is a computer, and a server program installed in the Web application server 110, which is a computer, are read by the respective processing devices. This is realized by being executed by each processing device.

  In the program activation system 200, the definition file 112 is stored in advance in the activation information database 115 of the Web application server 110. As described above, the definition file 112 is set by manual input or automatic input from the Web application server 110 or the full path (startup related information) manually input or automatically input by the client terminal 100 as the Web application server 110. There are settings by uploading to.

  For example, in the Web application server 110, it is assumed that link data of business P, business Q, business R, and business S is defined in the list display HTML data 111. The business P and Q (Web application) define a URL for starting a general Web application. The business R and S are defined so that the definition file 112 for starting the client application can be downloaded. In the definition file 112, the full path of the execution file of the client application 103 that is activated on the client terminal 100 is specified. Here, when there are a plurality of client terminals 100 and the full path of the execution file of the client application 103 is different for each client terminal 100, a plurality of full paths are designated.

<Display request transmission step: S201 to S202>
In step S <b> 201, the web browser 101 is activated by a user operation on the client terminal 100. In S202, the Web browser 101 transmits a screen display request for requesting display of the application list designation screen 104 (see FIG. 1) by the processing device. Specifically, the web browser 101 requests display of the application list designation screen 104 by transmitting a URL for displaying the application list designation screen 104 designated by the user to the web application server 110.

<Screen display information transmission step (display information transmission step): S203 to S204>
In step S <b> 203, the web function execution unit 113 receives a screen display request for the application list designation screen 104 transmitted from the client terminal 100. In S204, the display information transmission unit 1131 of the Web application server 110 acquires the list display HTML data 111, which is data for displaying the application list designation screen 104, from the screen display information storage unit 114 by the processing device. The display information transmission unit 1131 transmits the acquired list display HTML data 111 to the client terminal 100 that has requested the screen display request.

<Application list designation screen display step: S205 to S206>
In S205, the client terminal 100 receives the list display HTML data 111. In S206, the Web browser 101 of the client terminal 100 causes the processing device to display the application list designation screen 104 on the display device using the received list display HTML data 111. As shown in FIG. 1, the application list designation screen 104 displays a list of application names of application programs set in advance in the program activation system 200.

<Startup request information transmission step: S207 to S208>
In S <b> 207, the Web browser 101 receives an operation for selecting a specific application from the user using the application list designation screen 104 displayed on the display device. On the application list designation screen 104, the user does not need to be aware of whether the application program indicated by the displayed application name is a Web application or a client application. The application list designation screen 104 accepts an operation for selecting an application (specific application) to be activated from a list of application names from the user. The application list designation screen 104 accepts an operation for selecting a specific application by a selection operation by a click operation, a touch operation, a cursor movement from the keyboard, or the like from the user.

  The web browser 101 transmits activation request information for requesting activation of a specific application designated by the user to the web application server 110 by the processing device. The Web browser 101 transmits the application name of a specific application designated by the user to the Web application server 110 as activation request information.

<Activation-related information transmission step (activation information transmission step): S209 to S211>
The Web application server 110 receives the activation request information (application name) of a specific application transmitted from the client terminal 100 (S209). The activation information transmission unit 1132 of the Web application server 110 acquires the file name of the definition file 112 corresponding to the application name included in the activation request information from the screen display information storage unit 114 by the processing device. The activation information transmission unit 1132 acquires the definition file 112 corresponding to the file name of the acquired definition file from the activation information database 115 by the processing device (S210). The activation information transmission unit 1132 transmits the acquired definition file 112 to the client terminal 100 by the processing device (S211).

<Activation-related information receiving step: S212>
The web browser 101 of the client terminal 100 receives the definition file 112 transmitted from the web application server 110. For example, the web browser 101 downloads a definition file 112 corresponding to a specific application transmitted from the web application server 110 and stores the definition file 112 in the terminal storage device 105 of the client terminal.

  Here, the process of S201-S212 can be paraphrased as follows.

  The user activates the Web browser 101 on the client terminal 100 (S201), and requests the list display HTML data 111 from the Web application server 110 (S202). The Web application server 110 transmits the list display HTML data 111 to the client terminal 100 (S203, S204). In the list display HTML data 111, there is a description in which operations P, Q, R, and S can be linked. The list display HTML data 111 is displayed on the display device as the application list designation screen 104 by the Web browser 101 of the client terminal 100 (S205, S206).

  For example, when the user designates the business R by clicking with the mouse on the web browser 101 (application list designation screen 104) (S207), the web application server 110 links to the business R of the list display HTML data 111. The data (definition file 112) is transmitted to the client terminal 100, and the user can download the link data (definition file 112) defined in the business R (S208 to S212).

  For example, it is assumed that the user requests activation of the business R client application 103r (103rb) from the client terminal 100b. At this time, the definition file 112r downloaded in the client terminal 100a stores the full path 1121ra of the business R client application 103ra in the client terminal 100a and the full path 1121rb of the business R client application 103rb in the client terminal 100b (FIG. 2). reference). Therefore, in the client terminal 100a, it is necessary to execute a process of selecting the full path 1121ra for starting the business R client application 103ra in the client terminal 100a from a plurality of full paths stored in the definition file 112r.

<Application start step (program start step): S213 to S214>
When the client terminal 100 receives the definition file 112 from the Web application server 110, the processing terminal activates the information reading unit 102.

  For example, in the program activation system 200, a unique file extension (SCU or the like) is set in advance in the definition file 112 downloaded to the client terminal 100. In the client terminal 100, a unique file extension and an information reading program for executing the information reading unit 102 are associated in advance using an OS (operating system) function. When the definition file 112 with a unique file extension (SCU or the like) is downloaded, the client terminal 100 recognizes the unique extension of the definition file 112 by the Web browser 101 and automatically starts an information reading program (S213).

  The information reading unit 102 (information reading program) activates a specific application using the downloaded definition file 112 (S214).

  FIG. 8 is a flowchart showing the flow of information reading processing of the information reading unit 102 in the present embodiment. The information reading process is realized by an information reading program stored in the storage device of the client terminal 100 being read by the processing device of the client terminal and executed by the processing device.

  In S301, the information reading unit 102 reads the definition file 112 stored in the terminal storage device 105 by the processing device.

  The information reading unit 102 reads the first activation related information (full path 1121) from the definition file 112 (S302). The information reading unit 102 determines whether or not there is an executable file at the position indicated by the read full path 1121 by the processing device. That is, the information reading unit 102 determines whether or not the path passes by the processing device (S303).

  If the information reading unit 102 determines that the executable file exists at the position indicated by the full path 1121 by the processing device (YES in S303), the information reading unit 102 executes the executable file (eg, “.. exe file "). Then, the information reading unit 102 ends the process.

  If the processing unit determines that there is no executable file at the position indicated by the full path (NO in S303), the information reading unit 102 determines whether there is an unprocessed full path. If there is an unprocessed full path, the information reading unit 102 reads the next full path and repeats the process (S302).

  When there is no unprocessed full path, the information reading unit 102 indicates that all of the full paths stored in the definition file 112 are information that cannot be used to start the application. (S305), and the process ends. At this time, the information reading unit 102 outputs an error message such as “Application cannot be started”, for example.

  For example, as described above, it is assumed that the user requests activation of the business R client application 103r (103rb) from the client terminal 100b. At this time, the definition file 112r downloaded in the client terminal 100b stores the full path 1121ra of the business R client application 103ra in the client terminal 100a and the full path 1121rb of the business R client application 103 in the client terminal 100b as activation related information. (See FIG. 2). It is assumed that the business R client application 103rb does not exist in the full path 1121ra in the client terminal 100b (the location “C: ¥ business R ¥ RR.EXE” of the business R client application 103ra in the client terminal 100a).

  In the client terminal 100b, the business R client application 103rb (execution file thereof) does not exist at the position corresponding to the first full path 1121ra. Therefore, the information reading unit 102 determines that the path does not pass and reads the next full path 1121rb. The information reading unit 102 determines that the full path 1121rb passes, and starts the business R client application 103rb.

  That is, the automatically activated information reading program reads the definition file 112 and repeats the execution file existence check in the full path for the number of full paths specified (stored) in the definition file 112. If the execution file exists, the information reading program can start the business application in the client terminal 100.

  Thus, the information reading process in the program activation method of the program activation system 200 ends. Then, returning to FIG. 7, the program activation method of the program activation system 200 ends.

  In the present embodiment, the following program activation system 200 has been described. The program startup system 200 is premised on the configuration of the client terminal 100 and the Web application server 110. In the Web application server 110, a “definition file” that describes the full path 1121 of the execution file of the client application 103 that is to be started on the client terminal 100 is described. 112 "is prepared (set) in advance. In the client terminal 100, the web browser 101 requests download of the “definition file 112” stored in the web application server 110. The client terminal 100 automatically activates (executes) the “information reading unit 102 (information reading program)” that reads the information of the “definition file 112”, and reads the full path indicated in the “definition file 112”, whereby the client terminal 100 100 applications are started.

  As described above, according to the program activation system 200 of this embodiment, the activation of the client application 103 on the client terminal 100 can be activated from the Web browser 101 in the same manner as the Web application 118.

  Further, according to the program activation system 200 of the present embodiment, not only a specific client application but also a plurality of arbitrary client applications can be activated. That is, according to the program activation system 200 of the present embodiment, by preparing the number of definition files in advance for a plurality of applications, not only a single client application but also a plurality of arbitrary client applications can be activated. .

  Further, according to the program activation system 200 of this embodiment, even in a system that is packaged with a plurality of applications and provided to the user, the user can activate the application with the same interface without being aware of the configuration of the application. Is possible.

Embodiment 2. FIG.
FIG. 9 is a functional block diagram of the Web application server 110 according to the present embodiment. 9, the same components as those in FIG. 2 of the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

  In this embodiment, the login user account and login password (login information 300) of the client application 103 corresponding to the self definition file 112 are stored in the definition file 112 stored in the startup information database 115 of the Web application server 110. (Description) For example, the definition file 112r corresponding to the business R client application 103r stores a login user account and a login password (login information 300r) for authenticating that the business R client application 103r can be activated.

  A description will be given of a mode of automatically logging in to the client application 103 using the login information 300 stored in the definition file 112 when starting the client application 103 in the client terminal 100. With the above function, the user can omit the login operation.

  In FIG. 9, the startup information database 115 of the Web application server 110 is associated with the application name of the client application 103 that requires login processing, and login information 300 used for login processing to the client application 103 indicated by the application name. Remember. The activation information database 115 stores login information 300 for logging in to the client application 103 in the definition file 112 corresponding to the client application 103 that requires login processing.

  In FIG. 9, the activation information database 115 stores the login information 300 of the client application 103 corresponding to the definition file 112 in the definition file 112, but the configuration may not be such.

  For example, the activation information database 115 may include a login information file separately from the definition file 112. In this case, login information 300 associated with the client application 103 (application name) that requires login processing is stored in the login information file. When the activation information transmission unit 1132 receives activation request information (application name) for requesting activation of a specific application from the client terminal 100, the login information corresponding to the application name included in the received activation request information is stored in the activation information database. It is determined by the processing device whether or not it is stored in the login information file. When the activation information transmission unit 1132 determines that the login information is stored in the login information file of the activation information database, the activation information transmission unit 1132 extracts the login information from the login information file and extracts the login information extracted together with the activation related information corresponding to the application name. Information is transmitted to the terminal device. The client terminal 100 receives the login information (and activation related information) transmitted by the activation information transmitting unit 1132 and logs in to a specific application using the received login information (and activation related information).

  As shown in FIG. 9, the definition file 112 stores a login user account “USR1” and a login password “PASS1” as login information 300 in advance. For example, the login information 300 is manually input by the user using the input device of the Web application server 110. Alternatively, the user may input login information from the input device of the client terminal 100 and upload the login information input using the Web browser 101 of the client terminal 100 to the Web application server 110.

  In FIG. 9, the definition file 112r corresponding to the business R client application 103r stores in advance login information 300r including a login user account “USR1” and a login password “PASS1”. Also, in the definition file 112s corresponding to the business S client application 103s, login information 300s including a login user account “USR2” and a login password “PASS2” is stored in advance.

  In the present embodiment, the processes from S201 to S213 (see FIGS. 5 to 7) in the program activation process of the program activation system 200 are the same as those in the first embodiment. In the present embodiment, the information reading process of the information reading unit 102 is different from that in the first embodiment.

  FIG. 10 is a flowchart showing the flow of the information reading process according to the present embodiment.

  10, S501 to S503 are the same as S301 to S303 in FIG. 8 of the first embodiment. In S503, when the information reading unit 102 determines that a path passes through the full path 1121 to be processed (YES in S503), the information reading unit 102 proceeds to S5031.

  In step S5031, the information reading unit 102 determines whether or not the login information 300 is stored (set) in the definition file 112 to be processed by the processing device. If the information reading unit 102 determines that the login information 300 is not stored (set) in the definition file 112 to be processed (NO in S5031), the information reading unit 102 proceeds to S504, starts the client application 103, and ends the process. To do. If the information reading unit 102 determines that the login information 300 is stored (set) in the definition file 112 to be processed (YES in S5031), the information reading unit 102 proceeds to S5032.

  In S5032, the information reading unit 102 executes the keyboard simulation process of the client terminal 100 by the processing device, and automatically inputs the login user account and the login password of the login information 300. Then, the information reading unit 102 advances the process to S504, starts the client application 103, and ends the process. As a result, the information reading unit 102 can start the client application in an executable manner without requiring a login operation by the user.

  In the present embodiment, the following program activation system 200 has been described. The program startup system 200 is premised on the configuration of the client terminal 100 and the Web application server 110. In the Web application server 110, a “definition file” that describes the full path 1121 of the execution file of the client application 103 that is to be started on the client terminal 100 is described. 112 "is prepared (set) in advance. In the client terminal 100, the web browser 101 requests download of the “definition file 112” stored in the web application server 110. The client terminal 100 automatically activates (executes) the “information reading unit 102 (information reading program)” that reads the information of the “definition file 112”, and reads the full path indicated in the “definition file 112”, whereby the client terminal 100 100 applications are started. If the login information 300 is entered (stored) in the “definition file 112” in advance, an automatic login process can be executed when the client terminal 100 starts up the application.

  As described above, according to the program activation system 200 according to the present embodiment, even when it is desired to activate the client application 103 that requires login processing, the user only specifies the application name from the application list designation screen 104. You can log in and start automatically.
