Hi,
See any servlet-related book (see Jason Hunter's message-footers), but hey,
even Sun's servlet docs and apidoc might help (they helped me, I hope ;-)
Or seek "Resources:" string at bottom of any message from this list!
You can keep Objects within same session, using HttpSession.getValue(String)
.putValue(String,Object), .removeValue(String) calls.
In JSDK 2.1 you can share Objects betwen all sessions and servlets using
similar calls within ServletContext - .getAttribute(),
.setAttribute(), .removeAttribute()
If you run a previous version of JSDK you can use public static methods or
variables, to share global Objects betwen all servlets and sessions
(except for few distributed, multiple JVM, servlet-engines).
