No. JServ is a servlet engine for Apache. It doesn't support JSP alone,
and
it's not compliant with last version of servlet API. Tomcat, a part of
Jakarta
project, is its successor : it's both a servlet (2.2 compliant) engine
and a
JSP (1.1) engine.

It's Java Server-Side Include, the java equivalent of traditionnal SSI.

You'll need PostgreSQL for storing the data, JDBC driver to access them,
Tomcat
to process your servlets and JSP pages, Apache eventually if you also
have
plain HTML, as Tomcat is stand-alone capable. I don't know for JSSI, but
for
accessing data, this already largely enough.
