      when the client app try to instantiate the stateless session bean of the Interest sample, the follow error trigger:

      java.lang.NullPointerException
      at sun.rmi.transport.StreamRemoteCall.exceptionReceivedFromServer(StreamRemoteCall.java:245)
      at sun.rmi.transport.StreamRemoteCall.executeCall(StreamRemoteCall.java:220)

      Interest on 1000 units, at 10% per period, compounded over 2 periods is:

      at mio.InterestClient.main(InterestClient.java:62)


      what's wrong ????

      the client class are using this properties of JNDI:

      System.setProperty("java.naming.factory.initial",
      "org.jnp.interfaces.NamingContextFactory");
      System.setProperty("java.naming.provider.url",
      "localhost:1099");
      System.setProperty("java.naming.factory.url.pkgs",
      "org.jboss.naming:org.jnp.interfaces");



      thanks a lot !!!
