JSF：等待派对，然后重定向

Question

I'm using JSF 2.0 and Glassfish 3.1 and have the following problem:

I've got an application in which two users must participate. The first user should set up the session and then get to a wait page. When the second user joins, the first one should be redirected to the application page. Is this possible in JSF, and if yes, how?

Answer 1

• Create an Ajax polling mechanism
• Invoke an action from Ajax, check if condition met
• If met using JavaScript code redirect the user (Or you can also make it redirect from action)
