Subject AW: Access Component tree from a Servlet Filter
Date Thu, 14 Feb 2008 15:44:42 GMT
Thank you a lot.
Thats a very good tip.

I am experimenting to implement the following usecase:

Before a given view is displayed, I want to intercept the rendering, check if
Access is allowed. If its allowed, I want to render the response. If not, I want
to forward the user to a login page.

Currently, I am using a PhaseListener. It is running for the RENDER_RESPNSE phase.
Now, now do I implement the tricky part? I know if a user is allowed the view
a given view, but how do I cancel rendering and forward to another page?

Is there any other good solution available for this usecase?

Thanks a lot
