Subject RE: Validating in Action?
Date Thu, 01 Jun 2006 15:42:37 GMT
You can use the ActionMessage constructor that takes a string and a
boolean indicating whether or not the string is a key to be looked up in
a resource bundle. By setting this to false, the string is taken as a
literal.

public ActionForward execute(ActionMapping mapping, ActionForm form,
            HttpServletRequest request, HttpServletResponse response){
	...
	  String myMessage = ...; // app logic that returns a string

   	  ActionMessages errors = new ActionMessages();

	  // use GLOBAL_MESSAGE if message does not pertain to a
specific property
        errors.add(ActionMessages.GLOBAL_MESSAGE, new
ActionMessage(myMessage, false));
        saveErrors(request, errors);
}

Subject: Validating in Action?

Hi,

I got a JSP, form and Action.
I want to add 3 values into an database.
This is done in my action.
The problem: I am using a Service to add the stuff to the db, and when
using this service, it throws error messages like "artikel not found" or
"project not found".
Now I want to display these errors to the user -

The problem is I can't do those error validation in my ActionForm,
because only after doing the action I will know wether or not it
succeeded - so how can I then set the appropiate errormessages and
forward to the jsp?


Thanks,

Marcus
