    try

        InitialContext ctx = new InitialContext();
        String serverName = System.getProperty("weblogic.Name");
        MBeanServer server = (MBeanServer)ctx.lookup("java:comp/env/jmx/runtime");
        ObjectName objName = new ObjectName("com.bea:Name=" + serverName + ",Type=ServerRuntime");
        Integer port = (Integer)server.getAttribute(objName, "ListenPort");
        String ListenAddress = (String)server.getAttribute(objName, "ListenAddress");
        String WeblogicVersion = (String)server.getAttribute(objName, "WeblogicVersion");
        System.out.println("Server Name : " + serverName + "Listen Address : " + ListenAddress + " PORT : " +
                port + " WeblogicVersion : " + WeblogicVersion);
    }
    catch(Exception e)
