J2EE sessions are stored either as a parameter in the URL or as a cookie.
In this case it sounds like it's in a cookie which on IE for Windows will
automatically be sent back when using the standard URL classes.  For
HttpClient and most other systems you have to manually send the cookie
yourself.  You can retrieve it using javascript with document.cookie and
then pass it in to the applet as a parameter which can then be passed
through to HttpClient.

I believe Matt Drance from Apple has polished up these instructions for me
and posted them as a FAQ somewhere on Apple's site so it's probably worth
doing a bit of a dig around there for more info.  If you can't find it and
need more help I can do up some example code for you.
