Subject [jira] Created: (OPENJPA-1403) OSGi Aware Persistence Provider Implementation
Date Sat, 28 Nov 2009 13:31:20 GMT
OSGi Aware Persistence Provider Implementation
----------------------------------------------

                 Key: OPENJPA-1403
                 URL: https://issues.apache.org/jira/browse/OPENJPA-1403
             Project: OpenJPA
          Issue Type: New Feature
            Reporter: Milinda Lakmal Pathirage


Current OpenJPA trunk implementation doesn't have full support for using OpenJPA in OSGi containers.
For example when OSGi bundle which use OpenJPA deployed, OpenJPA persistence provider cannot
locate the persistence.xml in that bundle due to class loading differences in OSGi environment.
EclipseLink has resolved this by using bundle listeners and JPA specific OSGi bundle header.
Patch provided in this JIRA solve issues in OpenJPA in OSGi environment by following method
used in EclipseLink. But there is a problem with current OpenJPA implementation which caused
me to add Dynamic-Imports header to OpenJPA OSGi bundle to allow loading classes from bundles
that use OpenJPA. I think current OpenJPA implementation doesn't provide support to replace
central class load to support loading classes from bundles which use OpenJPA. If we have that
support we'll be able to remove Dynamic-Imports and make OpenJPA OSGi bundle follow OSGi best
practices .

Please review the path and provide your ideas about this patch.
