Albert Lee commented on OPENJPA-915:
------------------------------------
I am not familiar with Karaf. From just browsing the Karaf home site, it looks
like it is a osgi based runtime but without JPA container-managed persistence
support. Therefore it does not perform runtime enhancement.
Just a guess, I wonder if you can use -javaagent when launching Karaf so that
the enhancer can be tapped into Karaf's runtime.

> PCEnhancer cannot enhance an entity bean in a jar
> -------------------------------------------------
>
> Key: OPENJPA-915
> URL: https://issues.apache.org/jira/browse/OPENJPA-915
> Project: OpenJPA
> Issue Type: Improvement
> Environment: linux, java 1.6.0_12
> Reporter: Adam Hardy
>
> The PCEnhancer fails when trying to enhance an entity bean found in a jar. It
> tries and fails to write the enhanced class output to the jar rather than the
> build directory of the project.
> This means I cannot have my entity bean superclass in a seperate
> framework-centric project for re-use by all JPA-based projects, unless I
> enhance the class when jarring up the framework project. This would prevent
> me from sharing the jar with other JPA-based projects which don't use
> OpenJPA.
> I would recommend that the PCEnhancer checks the file path to write the
> enhanced class to before writing and removes any Jar-prefix if present,
> writing the class to the normal build directory.
