Our application is deployed in the server as three ear files. So it is creating three sessions per user.
Now we are trying to develop a log out for our application.

Till now we are able to kill only one session during log out which belongs to the same ear file where we have written log out code.

The place where we have written log out belongs to Home.ear
On the bottom portion there is an iframe which will load the jsps based on the tabs we clicked.
These jsps belong to other two ear files.

Is there anyway such that when we click the log out on the top, we can access the sessions in the bottom iframe and can kill that?
