You might try using the following JSP fragment (compliments of James Mitchell) on your page -- it will show you objects in the request, etc.

Here is how I prepare action messages in Action:

ActionMessages messages = new ActionMessages();
messages.add(ActionMessages.GLOBAL_MESSAGE, new
ActionMaessage ("something here"));
saveMessages(request, messages);

anything wrong ?
