Synchronize Class List problem when integrating JBoss with eclipseLink

The problem when integrating eclipseLink with JBoss 7.1
the attribute below in persistence.xml is not functioning

the workaround is to list all the entity class in persistence.xml.
but this is troublesome to developers, every time entities changed. the developers need to re-sync the entity classes again.

To avoid this troublesome step, we need to add additional module into JBoss AS7 to handle this eclipseLink integration.

The official document from JBoss is here.
And steps below are the simplified version of the official document.

1. Download the precompile jar from my drive.
2. Extract and copy the jar to JBoss modules folder
3. add the following line into standalone.xml

        <property name="eclipselink.archive.factory"



4. set persistence.xml to exclude classes and remove all synchronized classes.


p/s: the eclipseLink jar must be 2.4.2 or above
