Enterprise JavaBeans, Third Edition

The Deployment Descriptor

With a complete definition of the Ship EJB, including the remote interface, home interface, and primary key, we are ready to create a deployment descriptor. XML deployment descriptors for bean-managed entity beans are a little different from the descriptors we created for the container-managed entity beans in Chapter 6, Chapter 7, and Chapter 9. In this deployment descriptor, the <persistence-type> is Bean and there are no <container-managed> or <relationship-field> declarations. We also must declare the DataSource resource factory that we use to query and update the database.

Here is the deployment descriptor for EJB 2.0:
