Cool.
I have been doing lots of things so far using the session level, but never
used the application level.
I will probably get there when I finish my "team5.com" ecommerce sample.
This list has been really useful, and it is expanding a lot my knowledge.
Thanks to all of you
Sio

No. The ServletContext object has application level scope. This means that
all
users of a single web application access the same ServletContext object.
There is a
one-to-one relationship between Web Applications and ServletContext.
