Redeploy fails for struts application on JBoss-3.2.3
I have built a struts application and deployed it to JBoss 3.2.3. I have redeployed this application many times but recently, after making a minor change, I receive an error on redeployment. If I recycle JBoss the application works fine. Can someone suggest how I might debug this error? Below is the error log from the JBoss concole:
