Hi,
Are you still seeing this problem? Have you tried debugging to see why your
Persistence Provider service might be null?

Subject: KARAF and JPA Bundle issues - Urgent
From: mattmadha...@gmail.com

Hello,I moving couple of my sample applications from pax:provision to Apache
Karaf. Both application run ok on pax:provision inside of a Felix container.
But when I run the same applications (derby/openjpa 2.0, aries) I'm getting a
null pointer exception when I start my persistence bundle. The same bundle
worked fine in pax:provision!
Can some one send me an example or send me the list of Bundles/Features I must
have in order to make this work?
I would greatly appreciate it.
The errors are as follows:
The log says:2011-09-16 17:57:07,578 | INFO | rint Extender: 2 |

Any help will be appreciated.
