j2ee application authentication

[Tim Terry]

What possible methods are there to implement single sign on
authentication to multiple j2ee applications? Can this be done using
realms? At present I have two applications on the same virtual host,
each with their individual login screens. It would be good to allow the
user access to the applications running in all the contexts (same
virtual host) after a successfully login to one of them. I have been
trying to use a session based system, but i think a session is unique to
a context.
I'm running tomcat 5 if that helps.

Thanks in advance,


Tim

If you have both applications in one virtual host you can use the Single
Sign On Valve
