Configuring Table and Column Information

The EJB 2.1 specification does not prescribe how the abstract persistence schema of an entity bean should be mapped to a relational (or other) schema of a persistent store, or define how such a mapping is described.

However, using OC4J and the TopLink persistence API, you can do the following:

• Specify the table and column names of the database table associated with an entity bean with container-managed persistence.

• Specify how container-managed persistent fields and container-managed relationship fields should be mapped to your relational schema.

• Automatically create (and, optionally, delete) database tables for your persistent objects.

For more information, see the following:

• "Customizing the TopLink EJB 2.1 Persistence Manager"

• "Understanding Relational Mappings" in the Oracle TopLink Developer's Guide

• "Configuring Associated Tables" in the Oracle TopLink Developer's Guide

• "Configuring Automatic Database Table Creation"

Note:

In this release, orion-ejb-jar.xml file <entity-deployment> subelement <cmp-field-mapping> is not used. For more information, see "<entity-deployment>".
