[jboss-user] [Clustering/JBoss] - Re: ERROR [[jsp]] Servlet.service() for servlet jsp threw ex

[bstansberry@jboss.com]

This error happens when somehow your app is trying to load a class, and the classloader being asked to do it is a stale one left around from an earlier deployment of the webapp. Perhaps you redeployed the app but something is holding a ref to a class loaded from the previous deployment.

A quick solution is probably to restart the server.

Sorry I can't provide more details than this, e.g. how to find exactly what the cause is.  Suggest you post on the tomcat forum here at JBoss, or on the tomcat-user mailing list.  Be sure to mention what release you are running, as that *could be* very relevant.
