    ServletContext.getRealPath() does not work in JBOSS 3.2/Tomc

    jodybrownell1 Newbie

      Hello all,

      I have written an application listener to listen the contextInitialized event. At which time I am attempting to find the absolute file path of my
      application context via the following call ...

      String realPath = contextEvent.getServletContext().getRealPath("/");

      The value returned is always null. If I run this same code in tomcat 4.1.24 from jakarta (with no jboss) ... all is well. The path is resolved appropriately.

      Any thoughts? Does anyone know of a work around, or am I missing something obvious ....

      thanks in advance.

          When the servlet container cannot determine a valid file path for the method, such as when the web application is on a remote file system not accesible locally, in an archive or in a database, it will return null. So if your web application is still in a war, you will probably get this problem. In a standalone Tomcat, it normally unpacks the war so you can manifest a file path. Not so with the integrated Tomcat.

          Short version - you have no absolute file path when the application files do not manifest themselves in a real, physical way. Which is fine with the spec.

          I know that doesn't help much. You could try using properties already set but I'm not sure what you are after - for example you could read the jboss.server.home.dir. Or you can set properties in your web.xml for servlet initialisation. The only problem is the dependency inherent in this.

            Get real path only works with unpacked deployments.
            It is part of the servlet spec.

            You need to deploy your application using a directory
            structure that looks like a war file.

            deploy/myapp.war
            deploy/myapp.war/WEB-INF/
            deploy/myapp.war/WEB-INF/web.xml
            deploy/myapp.war/index.jsp

            etc.
