J2EE Registration Project (03) – Developing Enterprise Java Beans (EJBs)

We create the Enterprise Java Beans in the Business Tier of the project.

We right click on the RegistrationProject-ejb and create a new – other – Persistence - Entity Classes from Database. This will create our java file with the queries to select the data from the database as well as the constraint annotations and the getter and setter methods.

Then we again right click on the RegistrationProject-ejb module and select new – other – Enterprise JavaBeans – Session Bean for Entity Classes. We will create a local interface for this bean. This will create three more java files the abstractfacade, the facade, and the facadelocal.

The facadelocal program will be the interface program we will connect to from our servlets to send and receive data on the database.
