Do you have a stack trace or at least a Thread name for this? If so, please post that. This usually happens when the "old" application is shutting-down, and some component tries to load a resource form the ClassLoader. The most likely thing is that you have a thread in the "old" deployment of the application that is either still running, or still trying to shut down when Tomcat has already "stopped" the old deployment and told the WebappClassLoader not to load anything else. The solution is to make sure that you stop all application-started threads before your application stops. Or, equally likely, you need to make sure that driver-created threads are started using Tomcat's ClassLoader and not that of the web application. You might want to check to make sure you have the latest version of your DB2 JDBC driver. Also maybe do a web search for "drivername + classloader" will find information on preventing the problem. Tomcat can be configured to call certain methods to "trick" a class into binding to the server's ClassLoader instead of the web application's ClassLoader on startup. I'm not exactly sure how that would need to be done with your DB2 driver, which is why I suggested the web search. -chris --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
