    Problem with MBean JBoss3.2.3 -> JBoss4.0.0

    Michael Maurer Newbie

      We have writen a MBEAN such as posted in the JBoss3.x docu: A Standard MBean Example page 118. (see code below)
      This worked wounderfull in JBoss3.2.3.
      After adapting the jboss-service.xml I was able to deploy it in JBoss4.0.0.
      Using the jmx-Console I am able to view all the properties stored in the MBean. But when I try to connect to the MBean using JDNI

       Context ctx = new InitialContext();
       serverSettings = (ServerSettings)ctx.lookup("java:/MARSServerSettings");

      from my application (inside Jboss) I am able to invoke the bean and its methods, but the returned properties are null.

      Has anyone an idea whats the problem ?
      It seems to me that the MBean is not a singleton anymore!

      Cheers Michael
