    DeploymentException: Web mapping already exists for deployme

    Greg Ernst Newbie

      I am brand new to JBoss and am evaluating version 5.0.0 for a new development environment that is urgently needed.

      I have started with the simple example documented below and deployed the resulting war file to
      "C:/MyStuff/jboss-5.0.0/server/default/deploy/hello.war".

      Upon starting JBoss, I get the following exception:

      org.jboss.deployers.spi.DeploymentException: Web mapping already exists for deployment URL file:/C:/MyStuff/jboss-5.0.0.
      GA/server/default/tmp/deploy/hello56098-exp.war/

      I'll get an "HTTP Status 404 error . . . The requested resource (/hello.jsp) is not available" when trying to access the URL: http://localhost:8080/hello.jsp.

      Any help is most appreciated,

      Greg

          org.jboss.deployers.spi.DeploymentException: Web mapping already exists for deployment URL file:/C:/MyStuff/jboss-5.0.0.
          GA/server/default/tmp/deploy/hello56098-exp.war/


          By default. there is a ROOT.war in the deploy folder of JBoss which gets bound to / context. Earlier versions of JBoss did not throw an exception when some other application too tried binding its context to /. But looks like JBoss-5GA is stricter (which i believe is good) in this. So i would recommend you either remove the ROOT.war from the deploy folder or change the context-root in your jboss-web.xml to something else, like:

          <context-root>myApp</context-root>


          Then you can access the jsp through http://localhost:8080/myApp/hello.jsp

            jaikiran,

            Thank you very much! Your solution worked without a hitch. New versions can be challenging until documentation becomes mainstream.

              jaikiran,

              I had same problem and it's still.
              I changed "context-root" in jboss-web.xml but whenver i deploy WAR file again , this message "Web mapping already exists for deployment URL file" will occure.

              Please help me to solve problem , Thanks you

                As noted in my previous reply:

                You will have to remove the ROOT.war folder or rename ROOT.war to something else (ex: JBossRoot.war)

                  I removed the ROOT.war folder before run JBoss and re-deploy myApp.war but not work.

                  Please see output:

                    Notice that it is trying to install the war at /myApp context and is failing. Which means that there is some other application which is already deployed at /myApp context. You will have to check the logs to see which one it is.
