is there only static objects in Tomcat?

[Ray Letts <rl...@etc.bc.ca>]

I read a previous thread where someone stated that: "you know that 
Tomcat creates all objects as static?"

So then, if user A contacts a servlet via Tomcat that creates a person 
object and stuffs some personal info in it

and user B later contacts the same servlet via Tomcat that creates a 
person object and stuffs some personal info in it

that the person object is only created ONCE
and
that the personal info from user A is overwritten by user B's request?

that is my understanding of STATIC. Is this how Tomcat implements object 
creation? I guess it makes sense in the stateless web ....

thanks in advance

There is no such thing as "creating an object as static".  You might be
confusing this with creating a single instance of a servlet, which is
shared across all requests to that servlet.

Fundamentally, this means you cannot use static or instance variables in
our servlet class to maintain per-request state information.  Use local
variables in our methods, or pass things around as request attributes, in
order to deal with this.
