      prop.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory");
      prop.put(Context.PROVIDER_URL, "localhost:1099");

      Context initial;
      try {
      initial = new InitialContext(prop);
      Calculator beanRemote = (Calculator)initial.lookup("EJB3Sample/EntityCalculator");
      beanRemote.addFund("abc",0.1);
      beanRemote.addFund("Blaze",0.2);
      beanRemote.addFund("Apocalips",0.05);
      beanRemote.addInvestor("El DeCarcia",25,55);
      beanRemote.addInvestor("Marlon Brandes",20,60);

      for (int i = 1; i < 4; i++) {
      beanRemote.calculate(i,4-i,i*100*0.8);
      }

      beanRemote.getRecords();
      } catch (NamingException e) {
      // TODO Auto-generated catch block
      e.printStackTrace();
      }
