A possible cause for the behavior you see is that your servlet and JSP pages are
actually in two different servlet contexts (applications).
Using the default LWS configuration as an example, if you invoke your
servlet with a URL like
/servlet/foo
it's served by the default context. If you then invoke your JSP page
with a URL like
/examples/foo.jsp
it's served by the examples context. The two contexts have separate sessions,
as per the Servlet 2.2 spec.
If this is the case, simple change the way you call the servlet to
/examples/servlet/foo
or define an explicit mapping for the servlet in the examples context, instead
of using the invoked mapped to /servlet/*. You can then invoke the servlet
with a URL like
/examples/foo

Tomcat 3.1 RC1 supports URL rewriting.
<http://jakarta.apache.org/builds/tomcat/release/v3.1_rc1/>
I can't say I've done any extensive testing, but based on a few simple tests
(using only JSP pages) it seems to work. The problems you have with Tomcat may
be
caused by the same thing as I described for LWS above.
