JSP Session Management

I’m having a problem with session management when running jsp pages atop IS via WmTomcat. I have some things in place, but it’s not 100% correct. How do you all get the “proper” session ID when working within JSP pages?

It appears you, as a user, get multiple session ID’s depending on what you’re calling as a service. Can this session ID be isolated withing the WmTomcat package?

Thanks in advance!
