Description Tom Ware CLA 2010-05-06 10:50:27 EDT 
Updates in bug 311234 allow a persistence.xml file location and name to be specified through the eclipselink.persistencexml property.

Update our code so persistence units specified this way can be weaved.

proposed changes

These updates allow you to use the eclipselink.persistencexml property to specify the location of persitence.xml and enable weaving.

For Dynamic weaving with the java agent this must be specified as a system property since we will not be able to find the persistence.xml without the property.  (i.e. you are still required to have a single location and name for persistence.xml within all your persistence units.)

Checked in fix.

Tested manually.
Comment 3 Tom Ware CLA 2010-05-06 13:53:10 EDT 
eclipselink.persistence.xml property must be provided to enable this to work

Limitations:

1. When using with agent-based dynamic weaving this property may only define a single location and therefore all persistence units must use that location

2. Java EE servers will still follow the specification (and look for META-INF/persistence.xml), so when using an alternate persistence.xml location, you will not be able to use injection, and you will not get dynamic weaving

3. You will have to specify the location of the persistence.xml file using the -persistencexml argument when using the static weaver (or ther persistencexml attribute in the ant tast)
Comment 4 Tom Ware CLA 2010-05-07 15:23:36 EDT 
Additional Limitation. persistencexml must be a location contained within the base persistence unit location. i.e. don't use ".." in the persitence unit location.
