Subject Re: OpenJPA problems with multi persistence.xml
Date Thu, 12 Feb 2009 19:43:08 GMT

Hi Kevan

How is the property: 
openjpa.MetaDataFactory default setting. The default setting that comes with
geronimo causes openjpa to detect model from classes in the jar file
regardless of the persistence.xml 

What should I do to make openjpa look in the persistence.xml for classes
assigned to each persistence unit.

Please help

Thank
-B
