      Jboss 3,2,6 with Tomcat 5.
      Trying to reploy a web app by touching the web.xml and receive the following error:

      Using the default context with redeployable set to true. Using ROOT.war as a sym link to our web app directory. Deploys fine restarting jBoss.

      Any ideas? Any further info needed?

            Still have this issue and finally got around to creating a sample to recreate it:

            Error for the sample shows:

 HttpServletResponse response)

 {
 PrintWriter out = response.getWriter();

 out.println("Hello, betty!");
 out.close();
 }
}


            No context.xml

            Are we missing a necessary setting to get this to work?

            Any direction would be appreciated!

              Just an 'I have this problem too' msg I'm afraid.
              ever found a solution to this problem?
