Libraries in a WAR containing JSPs?

I've got a framework that is a mix of Java code and supporting jsp
files. Is there a way to jar this up and place it in the WEB-INF/lib
directory of another web application and still be able to address the
jsp files?

I don't necessarily need to directly address the .jsp files from the
outside, but would need to use things like RequestForwarded to access
them?

How do libraries typically include presentation layer capabilities like
this without using native servlets.

I don't know of any such thing and don't see how it could work if you did.

Check out the Model-View-Controller architecture and, possibly, Struts.

Why not code your servlets as servlets?

To answer your stated question, WARs aren't like JARs that go into WARs. A WAR
packages a Web _application_, not a library like JARs in a WEB-INF/lib/.
Cooperating Web apps can be packaged into an EAR (Enterprise Archive).
