2.5.1 Determining the J2EE applications to be executed

In this step, you determine the J2EE applications to be executed on a system.

You determine the basic components of a system configuration by identifying the application configuration suitable for the purpose of the system. For example, if you use a Web browser for the client, the application that you would use would be a Web application consisting of servlets and JSPs so that the application receives requests from the Web browser. You can also consider an application that will invoke the Enterprise Beans from servlets and JSPs, as and when required. In this case, the system would be a Web client system and you would need to determine the deployment of the Web server and the integration method for invoking Application Server from the Web server.

Also, if you are building a system that forms the basic component of a business system, you could also consider a configuration that uses EJB client applications for the client. You can also determine the usage of CTM depending on the types of Enterprise Bean of the calling destination.

For more details about the relation between the types of components included in an application and the system configuration, see 3.3 Determining the configuration of an application. For details about how to determine the system configuration when executing J2EE applications, see 3. Determining the System Configuration (J2EE Application Execution Platform).

For details about the functions that you can use according to the purpose of the system, see the description about purpose of the system and their corresponding functions in the following manuals:

For details about the application development procedures, see the uCosminexus Application Server Application Development Guide.

Reference note
Server operation mode
Hitachi recommends that you run the server in J2EE server mode (1.4 mode). You can also run the server in the servlet engine mode and the basic mode depending on the application type, but note that the basic mode is a compatibility mode.
