A "forward" change the current request processing from one servlet to another, but stay on server side, and the request object is the same.
A redirect send a response to the client (the browser), instructing it to send another request to the specified URL. The request object change because another request is issue.
Building a page with Tiles require that you keep the same request object until you complete the page. So, you can only use forward, and not redirect.

But when I want to tiles:put the output of the LoginState action into theI answer to me:
loginBox :

<tiles:put name="title" value="/pages/Title.jsp"/>
<tiles:put name="loginBox" value="/LoginState.do"/>
</tiles:insert>
, nothing appears.
My question:
is it possible to have tiles:put to display the output of an action, instead
of just the output of a (statically-referenced) jsp.
yes you can reference to a Struts action from a tile.
But this action must not forward to a result page via a redirection
(: <forward ... redirect="true"> will make the tile to display nothing.)
So my question is: why?
Having redirect="true" in the <forward> of an action is quite
good. But it is incompatible with tiles, which are also quite good.
Is it a feature?
