Assemble the application: Assemble the EJB module

The application assembly tool is used to package the enterprise bean files into an EJB module. The EJB module is used in later steps to assemble an application and deploy it into a WebSphere Application Server instance. The end result of an EJB module is a JAR file that contains enterprise bean files.

  2. The Welcome to the Application Assembly Tool window is displayed. On the New tab, click EJB Module, and click OK.

    The application assembly tool uses a navigation bar to access various parts of the interface. The EJB module file has a default name and directory structure and contains general EJB module information.
