Category: CatalinaBundle Group: v3.0 Rabbit Hole >Status: Closed >Resolution: Works For Me Priority: 5 Submitted By: Rajagopal Venkataraman (raja05) Assigned to: Scott M Stark (starksm) Summary: AbstractWebContainer Stop not setting contextclassloader Initial Comment: The stop method is not setting the contextclassloader before it calls performUndeploy. this leads to app that use the contextclassloader in the destroy method to fail during undeployment. See this thread for my post http://www.jboss.org/thread.jsp?forum=50&thread=32581 Struts uses the contextclassloader to get some resource in its destroy method. Since the threadcontext classloader is not setup, struts is nto able to find its resource. If i move my struts libraries to the default/lib directory, everything works fine as the appclassloader kicks in and is able to find the resource.

org.jboss.deployment.scanner.AbstractDeploymentScanner$S cannerThread.run(AbstractDeploymentScanner.java:202) I tried the struts-example that comes with Struts 1.1RC1. Im not sure how i can upload it here in this. i can send it to you if you need it. The deployment goes fine, Once you touch and redeploy the file, it throws the above exception. Also, i tried changing the AbstractWebContainer's stop method to get the webcontext classloader using the deploymentinfo and it still gives me the same exception. i will play with it some more, Thanks for the quick response. ---------------------------------------------------------------------- Comment By: Rajagopal Venkataraman (raja05) Date: 2003-05-11 12:01 Message: Logged In: YES user_id=206536

Im not sure how i can upload it here in this. i can send it to you if you need it. The deployment goes fine, Once you touch and redeploy the file, it throws the above exception. Also, i tried changing the AbstractWebContainer's stop method to get the webcontext classloader using the deploymentinfo and it still gives me the same exception. i will play with it some more, Thanks
