Hi David,
Thank you for your help, this example code might be very useful. What
I'm trying to do is centralised login service, to allow a central
authentication service to control acces to different web applications
that can even be in different hosts. I already succesfully implemented
the login part, but now I want to be able to logout from all the
applications at once, and I also want to be able to "trace" in one place
the user movements through the different applications. That's why I
thought about using JMS to implement the communication between the
different applications and the central authorization site. My concern is
now whether JMS, specifically Orion's implementation, is mature enough
as to have all my applications depending from it. Or are JMS
implementations in general as inmature and buggy as Michel J. Cannon
stated?
Thank you again,
D.
