Hi folks !
I'm trying to setup a JMS bridge beween JBoss Messaging running inside JBoss 5.1.0 and
WebSphere MQ 6.0.2 (WMQ) running as a standalone application.
Our major requirement is to have a Quality of Service (QoS) QOS_ONCE_AND_ONLY_ONCE between
both JMS Providers.
This QoS requires that both connection factories must be XAConnectionFactory
implementations.
The recommended way to integrate a JMS Provider inside a J2EE server is always to use the
available JMS Resource Adapter.
So for WMQ, we must deploy wmq.jmsra.rar in JBoss AS as explained on this wiki page:
http://community.jboss.org/docs/DOC-12535. And the JMS Bridge is working flawlessly when
using QoS QOS_AT_MOST_ONCE and QOS_DUPLICATES_OK. But as soon as we use QoS
QOS_ONCE_AND_ONLY_ONCE, the JMS Bridge doesn't start anymore and the following
Exception is thrown.
17:15:38,302 WARN [Bridge] jboss.messaging:name=JMSBridge,service=Bridge Failed to set up
connections
java.lang.IllegalArgumentException: Connection factory must be XAConnectionFactory

at org.jboss.jms.server.bridge.Bridge$FailureHandler.run(Bridge.java:1569)
at java.lang.Thread.run(Thread.java:619)
As a matter of fact, all JMS Resource Adaptors implement the ConnectionFactory interface
only as described in the J2EE Connector Architecture
Specification (JSR112). That's the case for IBM WMQ Resource Adaptor, Apache Active MQ
Resource Adaptor and JBoss Messaging Resource Adaptor as well.
So how is it possible to use the QoS QOS_ONCE_AND_ONLY_ONCE in a JMS Bridge if it is not
possible to obtain a XAConnectionFactory from a JMS Resource Adaptor ?
Do we have to connect directly to the JMS Provider to obtain a XAConnectionFactory instead
of using the JMS Provider resource Adaptor available ? If so, could you describe the
procedure to follow ?
Thank you very much for your assistance.
Bertrand
