So that I can compare the persistence.xml file. Currently I just copy pasted the very same org.apache.openjpa.PersistenceProviderImpl code and only changed the class name and checked. Still the same result. So I believe it is not something in the provider class I added. I have the openjpa code with me and appreciate any clue where I should debug ? > > Thanks > > > On Tue, Apr 30, 2013 at 8:09 PM, Subash Chaturanga <subash...@gmail.com>wrote: > >> Opps I made the error log to view so sloppy.
