I can confirm that the JNDI entry "XAConnectionFactory" appears only after Jboss failed to deploy our .sar.
Keep looking for a solution.
Thanks for any help
By changing the jboss deployment order, I managed to solve the issue.
But that's really not elegant, I'm sure there is a better way to configure (with a Mbean dependancy ? with a ressource-ref ?)
Anyway, I still wonder why it was working with hssql and why I met such issues with mysql.
<depends>e.g. on the UIL2 Service.
