If I understand it correctly, I don't think your modified tag works in all
cases. If, for example, you have a web-application called testApp and a
logon form at;
http://<someHost>/testApp/admin/logon.do
the ActionMapping defined in struts-config.xml must have a path attribute of
"/admin/logon" (I think) for the ActionServlet to find it (assuming you are
using extension mapping). To also find this mapping from your modified
FormTag you would need something like;
<html:form action="admin/logon.do" ...>
so in the output html it would write
<form action="logon.do" ...>
This is ok if your JSP page that contains this form is under the same branch
as the logon page e.g.
http://<someHost>/testApp/admin/changePassword.jsp
but fails if you are under a different branch such as;
http://<someHost>/testApp/cart/checkout.jsp
because it will produce the URL;
http://<someHost>/testApp/cart/logon.do
and not the one you want.
Note: I've not tested this so I may have got it completely wrong :-)
The approach I've taken is slightly different (and may also not work
properly). I do the same thing as you to look up the ActionMapping except I
only add the leading forward-slash if there isn't already one. To build html
form element, however, rather than stripping the path and making the URL
relative I prepend the context path (the name of the web-application) and
make it an absolute URL. In the above example the output html this method
produces would be;
<form action="/testApp/admin/logon.do" ...>
Which always works, I think. This basically copies the way redirecting
ActionForwards are handled in ActionServlet.
