sorry - when I said "instance" in this, I don't mean that at all - I really
mean I want variables that are independent and unique each time you call the
same instance. ie I guess I want:
public class blah extends HttpServlet
{
int x;
public void doGet (...)
{
if (some test)
{
x = 1;
}
else
{
x = 2;
}
evaluate ();
}
private void evaluate ()
{
out.println (x);
}
}
such that you can safely call that lots of times, simultaneously, and the
correct value of x will always be displayed.

Subject: instance variables in servlets
Hi,
I apologize in advance if this seems like a dumb question:
I've recently written my first servlet, and I guess due to a lack of
understanding on my part I gave the class a few member variables which
needed to be unique to each instance of the class.
Am I right in thinking that class member variables really just aren't a good
idea in servlets unless you want to share information between instances?
What I'd like to know is: is there a sensible way of having variables that
act like normal java class member variables (ie they're avaialble to all the
classes non-static functions) but which are safe to use without interfering
with other instances? Do I just need to make my class extend
SingleThreadModel?
Thanks,
Ben
