Configuring the CMP Resource

An EJB module that contains CMP beans requires the JNDI name of a JDBC resource or Persistence Manager resource in the jndi-name subelement of the cmp-resource element in the sun-ejb-jar.xml file. If the JNDI name refers to a JDBC Resource, set PersistenceManagerFactory properties as properties of the cmp-resource element in the sun-ejb-jar.xml file.

In the Administration Console, open the Resources component, then select JDBC or Persistence Managers. Refer to the Sun Java System Application Server Platform Edition 8.1 2005Q2 Update 2 Administration Guide for information on creating a new CMP resource.

For a list of the JDBC drivers currently supported by the Application Server, see the Sun Java System Application Server Platform Edition 8.1 2005Q2 Update 2 Release Notes. For configurations of supported and other drivers, see Configurations for Specific JDBC Drivers.

For example, if the JDBC resource has the JNDI name jdbc/MyDatabase, set the CMP resource in the sun-ejb-jar.xml file as follows:

<cmp-resource>
   <jndi-name>jdbc/MyDatabase</jndi-name>
</cmp-resource>

For another example, if the Persistence Manager has the JNDI name jdo/MyDatabase, set the CMP resource in the sun-ejb-jar.xml file as follows:

<cmp-resource>
   <jndi-name>jdo/MyDatabase</jndi-name>
</cmp-resource>
