JPA Application fails to start

[lalit.manchanda]

Hi,

I am working on a simple JPA app on Jboss Fuse 6.0, which is using openJPA as a provider, attempts to connect to postgres. It installs, but when starting it fails with the following error. I am attaching the pom.xml, blueprint.xml and persistence.xml being used for the project. I see some similarity of my issue with -http://fusesource.com/issues/browse/ENTESB-320

JBoss Fuse version 60015 is the beta release. The GA release is 60024. I suggest to upgrade and use the GA release.

[lalit.manchanda]

Hi,

I have tried with the GA release, still its the same problem.

[davsclaus]

Have you install camel-jpa feature first?

Also the dependency on the persistence api in your pom.xml should likely be provided scope.

[lalit.manchanda]

Hi Claus,

This was helpful, I could finally solve the problem. Two things which I want to check with you:

a. Why we need persistence api in provided mode?

b. Even if camel-jpa is not installed, and I install it post my FAB, my bundle should pick the dependency.
