I'd concentrate on the bit of code in your action:
> request.setAttribute("serverBean", new Server());
> Server s = (Server)request.getAttribute("serverBean");
> if (s == null) System.out.println(s.getWmId());
> else System.out.println("null");
If this returns null then nothing else is going to work. Try using different
