org.hornetq.jms.client.HornetQTopic cannot be cast to javax.jms.Queue

henrik-wl Jun 10, 2013 8:53 AM

I'm running the HornetQ libraries version 2.1.1-Final in Weblogic 10.3.5, and the above error appears whenever attempting to access the topic on the HornetQ server.

In Weblogic, I've configured the HornetQ server as a foreign JMS server, which is basically just a mapping of local JNDIs to remote JNDIs. There's no explicit way of saying whether a remote destination is a queue or a topic, so I'm a bit perplexed as to why this classcastexception is appearing.

Any ideas?

HornetQTopic is a javax.jms.Topic not a javax.jms.Queue, maybe one of your mappings is wrong but I dont really know enough about how Weblogic does that, probably moreof a question for the Weblogic guys

Well, there's no class configuration at all, it`s just a remote/local JNDI mapping, one for each destination and one for the CF. For some reason, the CF (which resides in the HornetQ library) attempts to cast this Topic object into a Queue object and I don't know why.

sound's like Weblogic is assuming it is a queue, I would ask on their forums.

Yeah, I've created a question there as well, but I'm leaving this open in case anyone comes along and has experience with this.
