I fixed this - I had a commons-logging-x.jar in my WEB-INF/lib.
But after removing this, I get another error:
WARN [TreeCache] node /JSESSION/localhost/genloop-demo/8gZM8DrZOd0IGqYY6C3Luw** not found
I have two jboss-4.2.1.GA (./run.sh -c all -b ip_node1/ip_node2) running. After shutting down node1 and submitting a request, I get this error on node2.
What does this "localhost" mean and how can I get a session-string that allows transparent failover?
To add some information, I run a JSF-application with tomahawk and client-side saving (javax.faces.STATE_SAVING_METHOD - client).
Thanks for any help to get this work.
