how to get current external URL *on forwarded page*
Joined: Mar 06, 2009
I am seeing something, maybe you can explain this. I think it has
something to do with "external" context..
When I enter my JSF web app, the browser address bar says
"http://myserver.com/jsfapp/index.jsf" for example. I click around in
it, and the address bar doesn't change, even though I am on a
different page, say http://myserver.com/jsfapp/newpage.jsp. (like in
When I am at this newpage.jsp, it has a header tag, and inside the
header tag java class I do this:
then s is "http://myserver.com/jsfapp/index.jsf"
If I do this:
then s is "http://myserver.com/jsfapp/newpage.jsp"
but I want s to be "http://myserver.com/jsfapp/newpage.jsf"
JSF is different from other webapp frameworks. The URL isn't so much a direct path to functionality as it is a handle to an ongoing conversation. That's why it doesn't change when you'd like it to.
That can be really irritating, however, when you want something you can bookmark or email to a friend.
A good solution is to use the PrettyFaces package to give you the ability to use direct URLs. It's quite easy to install and configure.
That's half the battle. The other half isn't as obvious - your problem. How do you get the bookmarkable URL presented in the user's browser?
Answer: a little magic in the faces-config file:
The magic is the "redirect" element. That basically causes the request to get routed out and back in again under the external URL you want, unlike the usual action, where the system just does a direct internal transfer to the destination.
It also confers another benefit. The J2EE container security framework doesn't understand the peculiarities of JSF - it maps security against the URL. By using the <redirect> element, the request gets resubmitted under the "proper" URL and the container security screen will be properly applied.
