Sun Java System Application Server 9.1 Developer's Guide

Automatic Database Schema Capture

You can configure a CMP bean in Application Server to automatically capture the database metadata and save it in a .dbschema file during deployment. If the sun-cmp-mappings.xml file contains an empty <schema/> entry, the cmp-resource entry in the sun-ejb-jar.xml file is used to get a connection to the database, and automatic generation of the schema is performed.


Note –

Before capturing the database schema automatically, make sure you have a properly configured CMP resource. See Configuring the CMP Resource.
