Replicated Session State problem

[brall]

I am using jboss 3.0.3 with Tomcat 4.x on Linux jdk 1.3.1. I have had good luck with the clustering and load balancing with jboss/tomcat, however I have getting an error when the server tires to replicate the https session information (I think):


11:26:06,710 ERROR [LogInterceptor] EJBException:
javax.ejb.EJBException: java.lang.ClassNotFoundException: election.data.UserSession (no security manager: RMI class loader disab
led)

My application is deployed as a ear file on both the servers. Even though I get this error the application
seems to run. The class in question election.data.UserSession is part of my war and is Serializable. It seems strange that I am getting an EJBException? Any pointers?

Is jbossha-client.jar in your classpath? If not try putting it in the classpath.

Adding jbossha-client.jar to my classpath didn't seem to help. Maybe I need to elaborate on the problem; I am seeing the problem when I access the web interface for my application. It looks like the server is having problems when it tries to replicate the HttpSession state between the clustered servers. The class that it is complaining about is stored in the session.

it seems that the class is not available on the other node. Try to put the JAR containing your shared classes under /lib or /deploy and check if it works.

Was anyone able to figure this out? I have my war file in the deploy directory but it still can't find the class. I even tried putting it in the lib directory but that didn't work either. I do want to keep it in the deploy or farm directory so that I can use hot deployment.

Nevermind, I figured it out. Thanks.

We run into the same problem.
How did you fix it?

Can you please try from a fresch CVS checkout from Branch_3_0: this should have been fixed by now (thanks to Scott). It is a classloader problem between servlet engine(s) and JBoss kernel.

Cheers,
