Hi I'm using Jboss cache 3.0.1 under jboss AS 4.2.2. I deploy a WAR with distributable attribute. When the server start, the following exception occurs: Failed to setup clustering, clustering disabled. NoClassDefFoundError: org/jboss/cache/TreeCacheListener" How Can I fix it? Of course if I remove the distributable attribute in my WAR all works fine Thanks Roberto View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4198943#...
