Neither. It's a servlet specification issue -- particularly how mappings
are applied (see Chapter 11 for more on how extension mapping for patterns
like "*.jsp" works in a servlet world).

You can acquire extra path info in a JSP page if you define an exact
match <servlet-mapping> for your page.
Of course, I think you're nuts to even try ... JSP is for the view layer;
you should be processing transactions through a servlet (which would then
forward to a JSP page for display) with something like the Struts
Framework <http://jakarta.apache.org/struts>. Then it wouldn't even be an
issue.
