Rendering a page without a .tml template?
Hi,
In my tapestry app, in some cases, I want the HTML to be entirely generated
without Tapestry's intervention.
For example, hypothetically, I have MyPage.java but a missing or empty
MyPage.tml whose content does not matter. Ideally, MyPage.java would
somehow conjure up the contents and my HTML would not be touched by
bootstrap (or however it's done). I tried multiple things, including
trying to override the rendering steps, but no matter what I do, Tapestry
either complains there's no content (even though there is), or it adds the
<html><head> and all the stuff I really don't need.
Any idea what I should do?
Jonathan

Hello Jonathan,
A page's onActivate() page can return something, for example, a
org.apache.tapestry5.StreamResponse or a java.net.URL. (see
https://tapestry.apache.org/page-navigation.html#PageNavigation-ComponentEventRequests&Responses
for more). That way, you could have a page class that serves a static file.
(I understood serving the static file by just putting it into
src/main/webapp is not the way to go as you need that page class for
something).
I was trying to imagine why you would not want a page to generate output.
Perhaps putting that logic into an event handler is a better way to go?
Cheers,
Volker

As Volker mentioned, your page should have an onActivate() method that
returns a StreamResponse (maybe a TextStreamResponse if the context is
text) instance which wraps the content you want returned. The page wouldn't
have a template at all. That's a completely normal thing to do using this
framework.
