I think that without being
VERY familiar with
Servlet 2.4,
JSP 2.0, and JSTL 1.1 specifications, you would be at a disadvantage when either taking the
test or working in the field.
However, these documents can be cryptic...much like consulting the "oracle at delphi"...so
you should also install a servlet engine (like
tomcat) and do some experimenting with code.
