Hi Saleem Mohammad.
           Thank a lot for your post. I got this idea from your link. The below code work fine.
          try {               
               InitialContext ctx=new InitialContext();
               Object obj= ctx.lookup("localejbs/sap.com/HelloMan_EAR/HelloManBean");
                ClassLoader homeCl = obj.getClass().getClassLoader();
                Class<?> localHome = homeCl.loadClass(HelloManBeanLocalHome.class.getCanonicalName());
                java.lang.reflect.Method method = localHome.getMethod("create");               
                Object homeObj = (Object)method.invoke(obj);
                ClassLoader localCl=homeObj.getClass().getClassLoader();
                Class<?> local = localCl.loadClass(HelloManBeanLocal.class.getCanonicalName());
                Class  args[] = {String.class};
                java.lang.reflect.Method localMethod=local.getMethod("helloMan",args);               
                Object params[]={"Thongie"};
                Object localObj = (Object)localMethod.invoke(homeObj,params);
                lookupText=(String)localObj;               
          } catch (Exception e) {
               // TODO: handle exception
               e.printStackTrace(out);
