Also, if you have been running your site with jsessionids for awhile
then the spiders have your jsessionid urls on their link frontier.
So the spiders will continue to crawl your site for jsession funky
urls even once you've prevented your tomcat from generating
them.  Tomcat strips the jsession part of the url before you get 
to test them so this can be hassle.

Try a apache mod_rewrite rule:
  <IfModule mod_rewrite.c>
        RewriteEngine On
        RewriteRule ^(.*)jsession(.*)$  - [R=404]
