It's quite simple, really, although it has nothing to do with a difference between JSP's and servlets (since JSP's are compiled into servlets). The JSP's and servlets both "live" inside a context, here the "demo"-web-application. Paths within scripting-elements in JSP's or servlet-methods are (as a rule) interpreted relative to this contxt, so "/" becomes "/demo/". But when you use a form in a JSP, the following request (after the user hits the submit-button) in fact comes from the client's browser (!), not from within your application. Therefore, the path is interpreted relative to the root-path of your Webserver (i.e. Tomcat or maybe Apache).

Montville [mailto:[EMAIL PROTECTED]] Gesendet: Dienstag, 13. August 2002 08:01 An: [EMAIL PROTECTED] Betreff: JSP vs. Servlet Paths Hi all, I'm new to this list and really need some help. Let me frame the scenario: I have CATALINA_HOME set to C:\jakarta-tomcat-4.0.4\jakarta-tomcat-4.0.4. The rest of the directory structure (and file locations) is as follows: CATALINA_HOME | +-- webapps | +-- demo | +-- jsp | +-- WEB-INF | +-- classes The "classes" directory contains MyServlet.class, WEB-INF contains web.xml, "jsp" contains both SourceJsp.jsp and TargetJsp.jsp. SourceJsp.jsp displays a submit button, which then calls TargetJsp.jsp, i.e., it contains the line "<FORM METHOD="POST" ACTION="/demo/jsp/TargetJsp.jsp">". I then have a Servlet, MyServlet.java that also calls TargetJsp.jsp. MyServlet.java contains the line "this.getServletContext().getRequestDispatcher("/jsp/TargetJsp.jsp").forward (req, resp)". Please pay attention to the path difference between these two calls. SourceJsp.jsp and MyServlet.java both "invoke" the same TargetJsp.jsp, however, the paths are different: SourceJsp.jsp = /demo/jsp/TargetJsp.jsp; MyServlet.java = /jsp/TargetJsp.jsp. I need to understand why this must be the case. What is the difference between a JSP invoking a JSP and a Servlet invoking a JSP with regard to the paths required for such invocation? Thank you for your help! I appreciate it!
