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

using Seam2.0.0.GA and JBoss4.2.1.GA

I'm getting the same exception with a session-scope SFSB.  Not sure why the ejb container is trying to prematurely passivate this SFSB.  When it happens, my use case persistence fails and I must restart the browser and start a new session as a workaround.

I'd like to know if there is an official fix or best practice design to avoid this.   I will try the above poster's advice of using the @PrePassivate callback method to cleanup resources as required.

Again the root cause exception seems to be the following and is confusing as most likely it's in the jboss classpath.
