Subject Problem with ActiveMQ to Weblogic route
Date Tue, 12 Jul 2011 11:09:33 GMT
Hi everybody, 

I'm having trouble with a Camel route from ActiveMq to Weblogic. 

The use case is very simple, I have a Tomcat and an ActiveMq instance on the
same server. 
The application in Tomcat is posting in the local ActiveMQ and the Camel
route is forwarding the message to the queue in Weblogic on a different
server. 

Every time a message is posted this exception appears in the log: 

org.springframework.jms.UncategorizedJmsException: Uncategorized exception
occured during JMS processing; nested exception is javax.jms.JMSException:
Could no disambiguate on queue|Topic-name totransform pollymorphic
destination into a ActiveMQ destination: testjmsmodule!ToActiveMq

org.apache.camel.component.jms.JmsProducer.processInOnly(JmsProducer.java:309) 
at org.apache.camel.component.jms.JmsProducer.process(JmsProducer.java:99) 
... 


Despite the exception the message is delivered is the Weblogic ToActiveMq
queue, but as I need to switch now to a transactional delivery, the message
is will be rollbacked. 

Any idea what this error comes from? 


Below is my camel.xml config (using ActiveMQ 5.5.0, Camel 2.7.0 and Weblogic
9.2):

      </route>
  </camelContext>
