# A XML Reference for orion-ejb-jar.xml Elements

This appendix describes the elements contained within the `orion-ejb-jar.dtd`– the OC4J-specific EJB deployment descriptor. This appendix covers the structure and briefly describes the elements in this DTD; however, most of these elements are fully described in other sections of this book.

The DTD is located at `http://xmlns.oracle.com/ias/dtds/orion-ejb-jar.dtd`.

The description of this deployment descriptor has been divided into the following sections:

- Overall description of each element section–Each section of elements of this XML file is described in "OC4J-specific Deployment Descriptor for EJB".

- Element description–An alphabetical listing and description for each element is discussed in "Element Description".

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.

You should add your OC4J-specific XML files within the recommended development structure, similar to the one that Figure A-1 shows:
