Re: external link to a tapestry page
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? Valdemaras Repšys wrote: Thanks for the answer, Aleksej.

Re: external link to a tapestry page
I can access the hivemind registry, i'm sending emails from the same application where the page is (a separate thread). I accessed the externalService on a mailsender thread, thou sometimes i get exceptions when invoking externalService.getLink: tapestry.url.LinkFactory: Error building service tapestry.url.LinkFactory.. Caused by: java.lang.NullPointerException : Property 'webRequest' of OuterProxy for tapestry.globals.RequestGlobals(org.apache.tapestry.services.RequestGlobals) is null.

Re: external link to a tapestry page
The LinkFactory service is completely reliant on the servlet container it is running in. It's really not intended to be used outside of a specific http request. For your use-case friendly urls sure would make a huge difference.

RE: external link to a tapestry page
You're on the right track by using an External link. Make sure your page implements IExternalPage. We do something similar with one page that we wanted to be bookmarkable and the URL Format is quite similar to what you're trying. You'll still have to workaround problems of interdependency between apps if the URL format changes on a different version of Tapestry, and this doesn't account for authentication/security measures, but it's a start. /bd -Original Message- From: Valdemaras Repšys [mailto:[EMAIL PROTECTED] Sent: Tuesday, July 18, 2006 5:27 AM To: Tapestry users Subject: Re: external link to a tapestry page Thanks for the answer, Aleksej.
