I got some weird problem with session handling. Maybe I
misunderstand something about session. Don't the objects
stored in the session belong to the current session only?
Why can other sessions get the objects?
Here, I put a service reference to session:
session.setAttribute(SERVICENAME, ref);
Should I add the session id too to distinguish the key?
session.setAttribute(SERVICENAME+session.getId(), ref);
Could Qing DX give give some light on it?
Thanks!

I am not sure about this.
My understanding is that a session is unique for each conversation between
the browser and the server.
I guess in your case you are actually in one session. I mean, maybe a child
browser window(eg. pop windows) is in the same session as the parent. But if
you start a new browser window manually, you should be in different sessions.

that's what I understand ... the situation is, even different users
with different browsers can get the reference object from the session.
Isn't it weird? BTW, my web server is Tomcat. Is there any bug with it
for the session implementation?

in same session.
