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:

<!DOCTYPE ejb-jar PUBLIC "-//Sun Microsystems, Inc.//DTD Enterprise JavaBeans 2.0//EN" "http://java.sun.com/dtd/ejb-jar_2_0.dtd"> <ejb-jar> <enterprise-beans> <entity> <description> This bean represents a cruise ship. </description> <ejb-name>ShipEJB</ejb-name> <home>com.titan.ship.ShipHomeRemote</home> <remote>com.titan.ship.ShipRemote</remote> <ejb-class>com.titan.ship.ShipBean</ejb-class> <persistence-type>Bean</persistence-type> <prim-key-class>java.lang.Integer</prim-key-class> <reentrant>False</reentrant> <security-identity><use-caller-identity/></security-identity> <resource-ref> <description>DataSource for the Titan database</description> <res-ref-name>jdbc/titanDB</res-ref-name> <res-type>javax.sql.DataSource</res-type> <res-auth>Container</res-auth> </resource-ref> </entity> </enterprise-beans> <assembly-descriptor> <security-role> ...
