OC4J and the orion-ejb-jar.xml File

Whenever you deploy an application, OC4J automatically generates the OC4J-specific XML file with the default elements. If you want to change these defaults, you must copy the orion-ejb-jar.xml file to where your original ejb-jar.xml file is located and change it in this location. If you change the XML file within the deployed location, OC4J overwrites these changes when the application is deployed again. The changes only stay constant when changed in the development directories.

Oracle recommends that you add your OC4J-specific XML files within the recommended development structure as shown in Figure A-1.
