- yes, this is really was my problem (as usual :-( , not
Firebird/Jaybird nor jboss
Namely, first mdb, which sends message to the Queue, should to have the
folowing mapping:

* @...-ref res-ref-name="jms/MyQueueConnectionFactory"
* res-type="javax.jms.QueueConnectionFactory"
* res-auth="Container"
*
* @...-ref res-ref-name="jms/MyQueueConnectionFactory"
* jndi-name="java:/JmsXA"

_not "java:/ConnectionFactory"

- Thank you for suggestions again, David...
