Struts form submission using POST
How to submit a form to an external web link (not part of the current
web application)?
In struts action, all links are interpreted relative to web context and
therefore "forward" object specified in
struts-config does not work.
e.g.
public ActionForward execute(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response)
{
ActionForward forward =
mapping.findForward("constructionPage");
}
// Strtus-config:
<forward name="constructionPage"
path="http://www.externalformprocessor.com"/>
Web context: myapplication
URL in <forward> tag of the struts-config is evaluated as
"/myapplication/http://www.externalformprocessor.com" which
obviously is not a valid URL.
One approach is to append all form parameters as query string in URL and
use response.sendRedirectTo(...) method of HTTPServeletRequest class
but this is not desirable for security reasons.
Does any one know any alternative approach to submit forms to external
sites using POST?
Any suggestion will be appreciated.

RE: Struts form submission using POST
Posted by Andrew Hill <an...@gridnode.com>.
What are you actually trying to do here?
a.) Have the browser directly submit the form somewhere else
- or -
b.) have the browser submit to *your app* first and then and forward outside
from the action?
if(a)
then your execute code is irrelevant as you wont be going through the action
on submit - What you need is to have the 'action' attribute of the pages
form tag point at the external site. (Not quite sure how you would do this
using the struts tags as Im not familiar enough with their syntax)
if(b)
You cant do this using a server side forward. It would require a client side
forward (redirect). Ive never tried this with a POST rather than a GET, but
Im assuming that since your asking about it it doesnt work?
