XA and JBoss Services

[relgames]

Hello!

Our application uses EJB3 SLSB, JmsXA, EJB3 Timers, entity manager is configured for MySql XA Datasource.

I've read at http://wiki.jboss.org/wiki/Wiki.jsp?page=ConfigJBossMQDB that XA is not required for JMS, but is it true for JmsXA? May be we need to configure it too?
And what about EJB3TimerService?

Thanks In Advance!

EJB3TimerService uses the DS for persisting the Timers in the database. The default configuration in the EJB3TimerService uses

<attribute name="PersistencePolicy">jboss.ejb:service=EJBTimerService,persistencePolicy=database</attribute>

I am not sure if the EJB3Service needs XA DS, you can confirm this from the EJB forum
