.htm problem

[Mark Muffett]

I have a web site to which a lot of cross-links have been built up over time.  Inevitably the links are to pages with names like index.htm.  I would like to change these to jsp pages, but of course I can't change the name without breaking the link (and losing traffic).    Any ideas how I can put jsp functionality on a jsp page (I already have Tomcat serving out the .htm pages and I have tried simply using an htm page like a jsp page, but it doesn't work)?   Many thanks for any help.   Mark
