Any persistence manager in jboss has to implement the interface
org.jboss.ejb.EntityPersistenceStore
The JAWS implementation is in
org.jboss.ejb.plugins.jaws.JAWSPersistenceManager
I've just committed a refactored implementation of this to CVS. This
uses a Factory to create Command objects, one for each method in the
EntityPersistenceStore interface.
It should be possible to swap the Factory and Commands to work with a
different persistence mechanism.
The redesign proposal was in:
http://www.kpi.com.au/jawsarchive/0005/0043.html
Things changed a bit as I worked through it. I gave brief details of the
implemented design in:
http://www.kpi.com.au/jawsarchive/0008/0011.html
I shall be catching up on the javadoc comments over the next few days.

Justin
