    java.lang.NoClassDefFoundError: org/jaxen/VariableContext

    Fredrik Newbie

      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

      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!

          Hi,

          I also have the same problem which ends with an OutOfMemoryException.
          I started to get this problem when i started to use Stateful session bean.
          Is this have something to do with ClassLoading issues?

          Best regards,
          Bustanil Arifin

            Hi,

            I am having the same issue. Did you ever solve it? If so, how?

            thanks

              Same kind of problem, using JBoss 4.0.5.GA. Started when I had a new application scoped SFSB in Seam.

              Very long and in a few minutes recurring stack trace begins with

              Seems like it cannot passivate.

              Jaxen is present in JBoss.

                I had this problem and fixed it.

                Before and EJB gets passivated, everything is serialized. Make sure your objects can be fully serialized - especially non-EJB beans that you create within your EJB. Also be sure to close any 'connections to external resources' you have open, if any.

                While you are developing, it's useful to define @PrePassivate, @PostActivate etc. methods w/ simple System.out.println statements so you can monitor the lifecycle events w/out creating a mountain of trace info.

                  My problem apparently has gone away too, yesterday, so far running fine on two servers.

                  I happened to rearrange how two Seam components (both stateful with scope application) were interacting. (For completeness of record: I moved storing of some kind of "unique id" from the one executing on timer to its "manager" for robustness, and made them both inject each other instead of one way because I had to.)

                  Now the problem is gone. I.e. the recurring super long log entries related to passivation and mentioning "java.lang.NoClassDefFoundError: org/jaxen/VariableContext" are gone.

                  It may have been related to a system exception in its method blasting a stateful session bean into non-existence. Not sure.

                  Point is, the problem went away when I cleaned up code.

                  Point is, the log didn't point at the cause, at least not in a way recognizable to me, which might not be anyone's fault or fixable. Just something to remember for next time.

                    Hi,

                    so what did you actually do to solve that problem?

                    Thx!

                      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.

                        Did you solve this problem? I have more or less the same exception in a different problem space (executing Groovy script in a SLSB and providing an invalid Script which causes a groovy exception)...

                        Any hint would be helpful, thanks!
