While deploying CMP entity beans, which fields in the bean are container-managed and how are they identified?

Tim Rohaly

Container-managed fields may be specified in the bean's deployment descriptor. An entity bean, for example, has an XML deployment descriptor containing elements similar to the following:<br/>

    <description>This entity bean models an audio compact disc.</description>

In the above deployment descriptor, the container-managed fields are specified to be upc, title, artist, type, and price.

While the deployment descriptor provides information about the container-managed fields for use during deployment, the details of how these fields are mapped into the database (or other persistent storage mechanism) are controlled by the container-specific deployment process itself. To learn more about the container-specific deployment process, you will need to consult your container vendor's documentation.
