Also, this way, you need to distribute just the client JAR file to the client layer. The client project is already setup as a utility JAR project and the EJB and Web project already has dependency setup to that project. For a small application, it is convenient to create such common classes in the EJB client project.

Both the EJB and client layer need access to this class. The JavaBean is a Data Transfer Object (DTO). We will have a session EJB that will contain the business logic. We will have a JavaBean that will hold the results of the square root operation. In the Confirm Perspective SwitchВ dialog, click on No. Our simple application does not need any additional features. In the Features secreen you can add support for Struts or JSTL. The client JAR file can be freely distributed anywhere.Д¬lick on Next. The EJB JAR file is installed only in the application server machine where the EJB module is deployed. The EJB client layer (the Web project in our case) should build a dependency on the client JAR file only and never to the actual EJB JAR file. Switch on the check box next on the Test_EJBClient.jar file. In the Project ExplorerВ view, right click on Dynamic Web ProjectsВ and select New->Dynamic Web Project. (The concept of a utility JAR project is fairly old and a discussion of this is beyond the scope of this tutorial). The EJB project вЂ“ Test EJB вЂ“ has a Java JAR dependency on the client project. How does the EJB project refer to the home and component interfaces in the EJB client project? The EJB client project is setup in the enterprise application project (Test Application) as a utility JAR project. The project contains minimal classes and interface for a EJB client application to compile and execute. What is a EJB client project? It is a plain Java project that holds the remote/local home and component interfaces, and generated stub classes. Accept the default name of the EJB Client project and JAR file name. As the EAR project, select Test Application.Д¬lick on Next. In the Project ExplorerВ view, right click on EJB ProjectsВ and select New->EJB Project. In RAD v6, a test server is automatically created. The target server determines the J2EE JAR files that are added to the projectвЂ™s class path. Note that the default J2EE level is 1.4 and that the new project will be targeted to WebSphere Application Server v6.0. In the Project ExplorerВ view, right click on Enterprise ApplicationsВ and select New->Enterprise Application Project.Д®nter Test Application as the name of the project. System shows/hides menu items based on the selected roles.Д¬lose the Welcome screen.

Click on the Advanced J2EEВ role as shown above. Click on OK.ДЄt the bottom right hand corner, click on the Enable/Disable rolesВ icon. Start RAD v6 (Start Menu Programs->IBM Rational->IBM Rational Application Developer V6.0->Rational Application Developer).Д®nter a short directory name as the workspace root folder.

If the number is missing or negative, system displays an error page. You will develop a very simple application that calculates the square root of a number.
