I'm not an expert on hibernate or atomikos, but I don't think hibernate
should ever see the raw PGXADataSource object. Whatever is handling the
connection pool, either Atomikos or JBoss, should get a connection from
the XADataSource object, and wrap that in a DataSource implementation of
it's own. That wrapper object is registered in JNDI, and hibernate gets
it from there.
Where is the connection pool configured? What's in the jboss cache and
how is it modified?
