RE: Forwarding Data For A Form
Jake, Thanks for the tip. I hadn't thought of prepopulating a form and pushing onto the request object before returning the ActionForward. Is the form name (i.e. key) you store the form under in the request object the same as that set in the name property of the action tag in the action mapping? I'll give this a try as nothing else has worked like I want.

RE: Forwarding Data For A Form
Jake, Just to follow-up, this worked exactly as I would have hoped. For anyone interested, this approach is useful to handle situations where information is accumulating across multiple forms and beans each subsequent form needs some of the data from earlier forms. Off the top of my head, it seems like it would be useful to be able to stuff Objects into an ActionForward that are then made available to ActionForms for just this purpose. I don't mind using the request/session objects, but since an ActionForm will be instantiated anyway as part of the forward, it would seem to be more direct just to make Objects available at the time the ActionForward is created. Thanks a lot for the help.

RE: Forwarding Data For A Form
Let's assume your jsp is named login.jsp and that it has a corresponding form bean named LogonForm. In the forwarding Action instantiate an instance of Logon Form and then put it on the request (using setAttribute). i.e. LogonForm logonForm = new LogonForm(); logonForm.setUserName(milton); ... request.setAttribute(logonForm, logonForm); If your struts-config.xml has an action mapping with the bean name defined as logonForm and the form in your login.jsp forwards to this action mapping, then the fields will be prefilled using the form bean created in your calling action.
Re: Forwarding Data For A Form
According to my understanding of the problem, this is really a very typical requirement that the Action class needs to pass some information to its view (jsps). All you have to do is to set the userid as an attribute of request(or session) scope. And then in the login.jsp, you can use bean:write tag to pick up its value. Further, in your case, you may want to use this tag for both displaying and setting the value of a hidden element.
