Resending... The original message never showed up in the archives so I'm
assuming it didn't get through.

A couple of additional notes

1) I found Guillaume Nodet's patch for the null username/password
problem in Generic RA on one of the Generic RA mailing lists.

2) The SessionAdapter class has a whole bunch of methods that should
probably be patched similarly to my change below -- I only changed the
one that affected me (for queues).

Cheers,
Raman

The generic RA outbound messaging works! Note that it is not yet heavily
tested. The following Spring config was sufficient (I am using WebSphere
MQ as the underlying JMS provider, I don't need XA so I turned it off):

  <bean id="jencksMq" class="org.jencks.JCAContainer">
    <property name="bootstrapContext">
      <bean class="org.jencks.factory.BootstrapContextFactoryBean">
        <property name="threadPoolSize" value="10"/>
      </bean>
    </property>
    <property name="resourceAdapter" ref="mqResourceAdapter"/>
  </bean>
  <bean id="mqResourceAdapter" class="com.sun.genericra.GenericJMSRA">
    <property name="queueConnectionFactoryClassName"
              value="com.ibm.mq.jms.MQQueueConnectionFactory"/>
    <property name="queueClassName" value="com.ibm.mq.jms.MQQueue"/>
    <property name="supportsXA" value="false"/>
    <property name="providerIntegrationMode" value="javabean"/>
  </bean>
  <bean id="mqConnectionFactory"
class="org.springframework.jca.support.LocalConnectionFactoryBean">
    <property name="managedConnectionFactory">
      <bean
        class="com.sun.genericra.outbound.ManagedJMSConnectionFactory">
        <property name="resourceAdapter">
          <ref local="mqResourceAdapter"/>
        </property>
        <property name="connectionFactoryClassName"
          value="com.ibm.mq.jms.MQConnectionFactory"/>
        <property name="connectionFactoryProperties"
value="TransportType=1,QueueManager=QM,HostName=HOST,Channel=CHNL" />
        <property name="queueClassName" value="com.ibm.mq.jms.MQQueue"/>
        <property name="supportsXA" value="false"/>
        <property name="providerIntegrationMode" value="javabean"/>
      </bean>
    </property>
  </bean>

  <bean id="genericMqTemplate"
        class="org.springframework.jms.core.JmsTemplate">
    <property name="connectionFactory" ref="mqConnectionFactory"/>
  </bean>

In order to get this working, I had to make two minor modifications to
the genericra code:

1) Guillaume's patch to handle null username/passwords.

2) The SessionAdapter.getWrappedDestination() method was attempting to
cast a javax.jms.Queue implementation incorrectly. So I modified the
method to be:

if (dest instanceof com.sun.genericra.outbound.DestinationAdapter) {
    return
(javax.jms.Destination)(((com.sun.genericra.outbound.DestinationAdapter)dest)._getPhysicalDestination());
} else {
   return dest;
}
