form post on external page
I am looking to do something equivalent to a simple html-form like this
with Tapestry:
<form method="post" action="https://www.somewhere.com/somepage.asp">
<input type="hidden" name="var1" value="1"/>
<input type="hidden" name="var2" value="2"/>
<input type="text" name="var2"/>
<input type="submit" value="Submit"/>
</form>
My problem is, that I do not know how to make activate the external page
in the action attribute, and then how to post parameters.
I am sure this is a very basic thing, but I have not been able to find
any documentation on it in my book or on the web.
Could someone please either tell me where to read up on this problem or
how to do it?
Thanks

In this case, there is no need to use a form "component". Simply use
<form>. If you need to make some parameters dynamic, like hidden
fields that pull information from your Tapestry application, use @Any:
<input jwcid="@Any" type="hidden" value="ognl:whatever..."/>

In this case, you are going to have to do a http post
to the other page. Look at the http client project in
jakarta commons. They have some examples of posting
to web pages and retrieving the results. There is
nothing specific to tapestry (or struts, webwork,
whatever) that would do this for you without lots of
work!
Hopefully this answers your question.

I guess I put that wrong, let me try again: What I want to do is NOT
receive parameters from some html page, but have a Form component on my
page that posts parameters to some other page,
"https://www.somewhere.com/somepage.asp" in my example, a page that is
not part of my application.

The trick to posting a form to an IExternalPage from forms not
generated by Tapestry is to add this hidden field:
<input type="hidden" name="service" value="external/Search"/>
In your activateExternalPage method, pull the parameters from the
request like you would in a servlet, for example:
HttpServletRequest request = cycle.getRequestContext().getRequest();
String param = request.getParameter("var2");
This has an un-Tapestry-like feel to it, because it goes directly to
the request, but this is the easiest and most sensible way I've found
to integrate Tapestry into external HTML.
