Class Not Found Exception when remoting

[green804]

I am getting the following exception in JBoss when remoting. We are running Jboss in a clustered enviroment using JBoss 4.2.1.GA with Java 5. We are using EJB3 and Spring. Is there something I need to configure or set to make sure this class loads?

Well, it looks like the exception occurs on the server when Remoting is reading in an EJB3 invocation. The missing class, org.jboss.aop.util.MarshalledValue, is in $JBOSS_HOME/server/$CONFIG/deploy/jboss-aop-jdk50.deployer/jboss-aop-jdk50.jar, so make sure that jar's still there.

Thanks for your reply. I found the problem. This is a clustered environment, and the sys-admin set up the servers to point to a shared netapp. The tmp directory was part of that shared space. When I started one server everything was fine. Then when I started the next server, the temp files were getting overwritten.

That one took forever to track down. :)

Thanks for getting back to us with the solution!
