I have an ear deployment file, and I've added a jar and modify some tld in there. Tried updating the deployment, but the changes didn't take effect. I need to delete the previous instance and creating a new one that points to the same ear file, then the changes took effect. is there anything wrong? what is it should be done if I want the changes to take effect without deleting and creating a new instance, because this approach is not ideal in production environment. thanks
