[jboss-user] [EJB 3.0] - java.lang.NoClassDefFoundError: org/jaxen/VariableContext

When I upgraded from 4.0.4GA to 4.0.5GA I started to get problems with passivation, see below: 19:50:35,960 ERROR [SimpleStatefulCache] problem passivation thread javax.ejb.EJBException: Could not passivate; failed to save state at org.jboss.ejb3.cache.simple.StatefulSessionFilePersistenceManager.passivateSession(StatefulSessionFilePersist enceManager.java:363) at org.jboss.ejb3.cache.simple.SimpleStatefulCache.passivate(SimpleStatefulCache.java:196) at org.jboss.ejb3.cache.simple.SimpleStatefulCache$SessionTimeoutTask.run(SimpleStatefulCache.java:129) Caused by: java.io.IOException .... Caused by: java.lang.NoClassDefFoundError: org/jaxen/VariableContext I do not have any clustering turned on and should not have any caching but I still get this problem. The class org/jaxen/VariableContext is in the jar jaxen.jar in jboss_home/server/default/lib so why can Jboss not find his class and why is it needed. Any help is very much appreciated! /Fredrik View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3995539#...
