      Hi Guys,

                   I'm a beginner with Java/EJB. I'm trying to setup a basic session bean program. I went through many online materials and finally made a simple program.  I'm getting the following error when i run my client. i'm using jboss 7 and eclipse (kepler)

      My Bean Class is like this

      @Stateless

      @Remote(AllyRemote.class)

              // TODO Auto-generated constructor stub

          }

          public String callAlly(){

             return "Alucard";

          }

      }

       

       

       

       

      Remote Interface:

      ********************

      package test.psp.gdc.SEB;

        final Hashtable jp = new Hashtable();

        jp.put(Context.URL_PKG_PREFIXES, "org.jboss.ejb.client.naming");

        Context context = new InitialContext(jp);

        //App Name

        final String appName="";

      //Module Name

        final String modName="Lightning";

      //Distinct Name

        final String disName="";

        //EJB Name

        final String ejbName=Ally.class.getSimpleName();

      //view Class Name
