Notice that the postMessage method returns the string “theend”. You will also call the findAll and create methods that are exposed in the facade. You will now add an EJB annotation to use dependency injection to obtain a reference to the MessageFacade session bean. In the Projects window you will see the following files. When you click Finish, the IDE creates the bean class and opens the class in the editor. In this exercise you will create a simple JSF managed bean that is used to access the session facade. You can use bean names in JSF pages to access methods in the managed bean. You are no longer required to add entries in the faces-config. You can see that the IDE generates some commonly used default query methods that can be used to find entity objects. In this example the name of the persistence unit is declared explicitly, but the name is optional if the application has only one persistence unit. As you can see in the generated code, the annotation Stateless is used to declare MessageFacade. Instead, in this application the bean will be exposed to a local managed bean using a no-interface view. Notice that you did not need to create a business interface for the session bean. In this application where the client accessing the bean is a local client, you have the option to use a local interface or a no-interface view to expose the bean. In this exercise you will use a wizard to create a stateless session facade for the Message entity.
This results in less code because the entity lifecycle is managed by the container and not by the application. This specifies that the responsibility for managing the lifecycle of entities in the persistence context is assigned to the container. In general, local functionality will be enough to almost any Java-developer. The program can also terminate code sections and check its correctness right during the process of writing.
