What has this to do with the Design of ESB? Moving to User Forums. Please post these kinds of queries there.
Yes, sorry that was my mistake but I couldn't move it afterwards. I just googled "jboss esb forum" and posted a message, previously google had forwarded me to to the user forum.
This seems to be some kind of class loader issue I presume, but I'm not sure. This exception occurs if I define " -Djboss.messaging.groupname=FESB_MessagingPostOffice" which I tought would help some of the clustering / lost JMS replies issues we're having.
We've two ESB clusters A and B, with two nodes on each cluster (totalling 4 nodes).
They share the same UDDI. This itself seems to be a little problematic.
Cluster A hosts services which are used through webservice from a portal layer.
Cluster B hosts services which are used through JMS (ServiceInvoker) from cluster A.
Now, sometimes reply from a service in Cluster B does not come back to cluster A --> the web services times out. And this is what I'm investigating.
This only occurs when running on IBM JDK 6R3.
