If you get the following or similar error:

OC4J – (SEVERE) Failed to set the internal configuration of the OC4J JMS Server with: XMLJMSServerConfig (jms.xml)

You may need to delete all contents within the “persistence” folder:

[text]jdev10.1.3.5.adf\jdev\system\oracle.j2ee.10.1.3.43.6\embedded-oc4j\persistence\[/text]
