I'm running a servicemix cluster using JMSFlow. The app is deployed
as a webapp in Tomcat 5.5.20 running under a java5 jdk. I am using
the servicemix-3.0-release version. When the nodes broadcast to each
other, I'm getting a seriralization error on
javax.xml.namespace.QName on all nodes
It seems as though an unexpected version of this class is being
loaded by one of the nodes, yet I have exhaustively reviewed each jar
that is part of my app, as well as the ones in Tomcat itself - I
cannot find any that contain a different QName implementation, I
*should* only have the jdk1.5 version, which has uid
4418622981026545151.
I am at my wits end, has anyone seen this before? What am I missing?
Here is the stack trace:
