In your persistence.xml
> <jta-data-source>jdbc:/wineappDS</jta-data-source>
its jdbc[b]:[/b]/wineappDS
and
your JNDI Name is
JNDI Name: jdbc/wineappDS
without colon(:) after jdbc. Could that be a problem ?
If not, try setting log levels of ejb-container, cmp-container, connector to FINEST and attach the server.log.
