Creating a session bean
In this section, we create a Stateless session bean façade for the entity beans. Select the Model project node in Application navigator and select File | New. In the New Gallery window, select Business Tier | EJB and Session Bean in Items. Click on OK. In the Create Session Bean window, specify the session bean EJB Name, and select Session Type as Stateless and Transaction Type as Container. Specify a Mapped Name, which will be used to lookup the session bean from a client. Select a Persistence Unit and click on Next. Select the default session façade methods to generate and click on Next. Specify the Bean Class and click on Next. Specify the EJB interfaces to implement. Implement only one of the interfaces—local or remote. Select the Implement a Remote Interface checkbox, specify an interface name, and click on Next. In the Summary page, click on Finish. A session bean and a remote interface get created.
