I think it is the Apache::Session module which allows session
tracking in mod_perl. I have not used it, but I would guess it
uses cookies to track sessions just like Servlets do.
However, I would bet that the cookie name is different, so the
session tracking mechanisms will not talk to each other.
My recommendation would be to let a Servlet establish the session
(must be cookie based) (or you might figure out how to make
URL rewriting work). Then let your Perl scripts look for that
particular named cookie to continue the session.

There are many ways to store state information between calls.
The nice thing about Java Servlets is that you can store state info
in Java Session object. Obviously, this information cannot be
shared with perl scripts.
However, one piece of state information,
the session ID, is stored in a cookie (i.e. sent back the brower,
whereupon the browser sends it back the server every request).
You could store other pieces of state information as cookies
(as long as it was limited in volume). This state information can
be shared between Servlets, Perl, and any other active processing
you may have on your site.
A third way to share state information between Java and Perl is the
ugly "write it to a file" method.

Yes Apache can do both in the same server.
I think your question here is whether java servlets can share sessions
with Perl scripts running in mod_perl.
