Date Thu, 09 May 2013 15:17:53 GMT
Hi Rick,

Thanks for looking into this, the persistence.xml file we are using is:


https://github.com/apache/oozie/blob/trunk/core/src/main/resources/META-INF/persistence.xml

The EMF is instatiated here:


https://github.com/apache/oozie/blob/trunk/core/src/main/java/org/apache/oozie/service/JPAService.java#L156


Thanks again.

Alejandro
