Since the form you'd need to retrieve is named depending on the main page content, you won't know that information in the header (not easily anyway).
I mean, think of it this way... when your page is converted to a servlet, the header code is included in with the main page, and then the footer, so really you have one big chunk of code representing your page. The problem is that the CODE in the header doesn't know what page it's included in, and therefore doesn't inherently know the name of the form to retrieve. Remember that the includes are not done dynamically per request, they are done once when the JSP is converted to a servlet. (Caveat: I may be wrong about all this :) ) One approach would be that whatever Action your coming from, it should always stick the pages' form in request under some standard name (uhh, "form" strikes me as good?!?). That way, your header.jsp can always retrieve that known element and do whatever it needs to do. Alternatively, you could have a JSP variable in the main page that identifies the name of the actual form, and it's scope you'd probably need, and then be sure to include your header AFTER the point where the variables are declared, then your header should be able to access them since and use the information to retrieve the appropriate form. A third alternative, which I'm not sure will work (although I suspect it would) is to retrieve the ActionMapping of the page in the header. That should give you all the information you need to retrieve the form. -- Frank W.
