It works very well if you have a lot of jsp includes, each providing it's own templating functionality. In that case, you don't want the client to have direct access to those jsp files providing only parts of the overall page. Or maybe you want to be sure a servlet mapping handles the request in MVC style before passing on the request to the view via an internal forward. Either way, it helps protect the webapp from clients calling jsps out of the context they were designed for.
The servlet container probably just uses something like the servlet context's getResourceAsStream() to find the file, then compile it and make it available. I've never needed to do anything special in WEB-INF/web.xml or any other config file to let tomcat know to find them there. Just use the jstl tag <c:import url="/WEB-INF/jsps/myJspFile.jsp" /> and it's done. --David --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
