Maybe I didn't understand something. You want to send email from the
same webapp or from totally
different application? In other words, can you access and work Hivemind
registry of webapp where
your targeted page is?

Thanks for the answer, Aleksej.
The problem is, this URL must be generated on a java thread (or class)
that
is not an instance of BasePage and is not a tapestry page. That means
i have
no access to ExternalService, right?
Also, I can't use @Any component because this url will be sent as an
email
to the user (as a simple text).

Do not form links manually, use "tapestry.services.External" service (
in your case ).
First inject it into your page with something like:
<inject property="externalService"
object="service:tapestry.services.External" /> in your page file.
Be sure that you have a externalService property getter like:
public abstract IEngineService getExternalService();
Then, when you need to generate link, just use
"org.apache.tapestry.engine.ExternalServiceParameter"
to generate your page parameters ( name and Object[] ) and call
getExternalService().getLink( your parameter object ).
This will return ILink object and you will be able to call
getAbsoluteURL on it, which will return required Link as a string.
On the page you can probably put it using @Any component, like:
<a jwcid="@Any" href="yourLink">go go go</a>
