If you want the calling JSP to continue processing the request after calling
the other JSP, you can use <jsp:include>. If you don't want to continue
processing after the call, you can use <jsp:forward> (assuming the calling
JSP doesn't write anything to the response, explicitly or by just containing
template text).
But if you don't care about the output from the called JSP, maybe you should
consider if the functionality implemented by the called JSP would be better
implemented as a bean or a custom action. I know there are different opinions,
but I prefer to use JSP pages for presentation only (and possibly as face-less
request processing "front components" in fairly simple applications), and
other types of components for everything else (servlets, JavaBeans, utility
classes, EJBs, etc.).
