I routinely write web apps where servlets forward to JSPs, and relative references always work fine.

Now that you tell us this rather important bit of news things are much more

Tomcat doesn't allow urls [sic] that request resources inside this directory so my guess is that the
relavie references were failing because of this but it's just a

No wonder your "<%= getContextPath() %>" scriptlet didn't help.

guess. I changed my code so that index.jsp is the default page and I
noticed that this file was not able to load references to css when it
was inside WEB-INF so I move both css/ and images/ out of WEB-INF and
into web and it worked.

The reason you could get your page from WEB-INF/ is that access is through a
servlet forward. The reason that you couldn't get your CSS from WEB-INF/ was
that access was through a URL.

My guess is that if I go back to using my servlet as the default resource it will work now if I forward the
request to index.jsp or some other .jsp file. I'm not sure I want to
go back tho'.

There are a lot of good reasons to use a servlet to mediate view and logic
dispatch. Check out "Model-View-Controller" (MVC) and "Front Controller pattern".
