External URL Help

I am tasked to allow the following in our secure tapestry 
app:

1) Generate a URL That a person could mail to a 
perspective client.
2) That client client would click on the URL to sign up.
3) The URL would activate a Page within our system that 
would them look at a parameter in the URL to determine 
which person's URL was used to activate this page.

    I have been reading chapter 10 in TIA for how to use 
the External Link's and pages. It seems fairly 
straightforward.  Where I am getting stumped is that I 
need to give someone a URL like 
"www.signmeup.com/app?Salesman=John Doe" or something of 
that ilk.  This URL that I give needs to activate an 
External Page.  I guess what I need is to send an already 
rendered   external link.

    How do I do that?  I would also need to create the 
URL's on the fly so that I could generate one for a new 
salesman and they could email it to themselves/write it 
down or whatever.

    I am still quite green.  I have a full Tapestry app 
but I have not used alot of bells andn whistles yet.  What 
I am saying is don't assume I know a whole lot of teh 
Tapestry internals.

    Thanks Again in Advance.

    Doug

Hi Douglas.

Time to learn some of those Tapestry internals, or rather, APIs. ;-)
Look at the source for some of the link components to see how they do it.
In particular you need to use ILink - see page 333 of TIA, or do search
for it if you have the eBook edition.

Anyway, but here's a quick example.
Create a helper method in your page class.

     public String getSomeUrl()
     {
         // get the external service
         IEngineService service = getEngine().getService(
             Tapestry.EXTERNAL_SERVICE);

         // prepare the parameters
         Object[] parameters = new Object[]
         {
             "PageName",
             // other paramaters ...
         };

         // get the link
         ILink link = service.getLink(getRequestCycle(), this, parameters);
         return link.getAbsoluteURL();
     }

Check out the other methods in ILink to what it can do for you.

Cheers,
Nick.
