JPA 2.0 packaging : persistence units referencing other jar files using jar-file in JBoss EAP 6

Solution Unverified - Updated -

Issue

  • I am trying to deploy an EAR with a a layout like the following:
app.ear
        /lib/persistenceUnit.jar
                /META-INF/persistence.xml
        /web.war
                /WEB-INF/lib/web-entities.jar
        /other-entities.jar

The persistence.xml includes the following references:

<jar-file>../other-entities.jar</jar-file>
<jar-file>../web.war/WEB-INF/lib/web-entities.jar</jar-file>

When attempting to persist an entity (e.g. com.example.web.Entity) contained within web-entities.jar, the following error occurs:

Unknown entity: com.example.web.Entity
