    Invalid use of destroyed classloader

    fmaredia Newbie

      Using Apache AXIS, we get the following error after our application has been hot redeployed . There is no problem on the front-end, even as far as functionality, however an error is generated in the log. It seems that the class gets destroyed and does not seem to be rebuilt properly. I am not sure what I really need to do to resolve the problem. If I restart the JBoss server then everything works fine (once again initially until I redeploy then the error occurs again), however I do not want to restart every time I need to redeploy my application.

      The following is the error, once again it only appears after we redeploy the application:
