[T5] Handle post from external application
What is the proper way to handle a form post to a Tapestry page from an
external application? I know how to encode the parameters in the URL and
use the onActivate context, but in this case, the data being passed from the
external application will exceed the URL length limit so I need to use post.
Can anyone advise how to do this?

Inject the PageRenderLinkSource and use its
createPageRenderLinkWithContext() method to generate a Link. In this Link
object, use its addParameter() method to add the query parameters
(?parameter3=3¶meter4=4). Then return this Link in some event handler
method (onSubmit or any other). I have not tested it, though.

Thiago,
I know this thread is old, but I had a related question. If I submit a form
to a response page, what method can be used in the response page to redirect
to a URL like your "use both!" example? i.e. How can I append
"?parameter3=3¶meter4=4..." to the end of the context when redirecting
after POST?
The idea is to keep the Tapestry onPassivate URL context for real objects,
but allow optional, unordered parameters to be defined in a GET-style
parameter list. Is this possible in Tapestry? Thanks!

They're not mutually exclusive. They are just different ways to receive
parameters. Which one to use is all about the URLs.
Suppose the page that will receive the request is named "process":
www.example.com/process/parameter1/parameter2/parameter3: use onActivate
www.example.com/process?parameter1=1¶meter2=2: use Request.getParameter
www.example.com/process/parameter1/parameter2?parameter3=3: use both!
onActivate to get parameters 1 and 2 and Request.getParameter to get
parameter 3.

You can use Request in any method. You use it like you would use
HttpServletRequest. The difference is that your code depends only in
Tapestry, not in the Servlet API.

I was talking about posting from another web application to a Tapestry page,
but it really shouldn't matter where the post is coming from (i.e. Java
application, Perl script, etc).
My goal is to have a page that operates normally for Tapestry requests or
REST URL requests from onActivate contexts, but also have the same page be
able to respond to posts from other applications.
Thiago, can the approach you propose coexist with an onActivate context for
Tapestry requests or are they mutually exclusive? In what page method does
getting the request parameters happen (e.g. onActivate?) ?
Thanks!

We are talking about the client side which is a java app (for example)
that has to post data to the T5 web app for taking advantage of great
processing features provider by T5 you have to deal with the hidden
formadata parameter.
Please correct me if I'm wrong.

Inject the Request and use it to get the parameter values, just like you
would do without Tapestry. Tapestry adds a hidden field with some values
you better not try to deal with them. :)

You have to look at the generated HTML fro your page, grab the
t:formdata form parameter and (hard)code it into your app which will
post to T5, obviously you have to use the appropriate parameter too.
Of course you will tie together with that particular version of T5.
This way it'll do the job. Yep i know it's no more then an hack but is
the only way to do that right now, maybe (i think so) in the future T5
will have more RESTfull "features" to facilitate this but for now you
have to be satisfied.
I would like to see more discussion in this topic since i find T5 a
great framework to build web app for app (B2B or call that the way you
want), non only for browsers.
