    Which Spring version are you using? I have tested this with Spring 3.1.1.RELEASE, using the following simple application:

    Folder structure

spring-web
    |
     --- src
          |
           --- main
                 |
                  --- webapp
                         |
                          --- page
                         |     |
                         |      --- home.jsp
                         |
                          --- WEB-INF
                               |
                                --- web.xml
                               |
                                --- applicationContext.xml

home.jsp

<mvc:annotation-driven />

    On accessing http://localhost:8080/spring-web/page/home.jsp, the URL is correctly displayed as http://localhost:8080/spring-web/page/home.jsp.

    The best way would be to use EL like this:

    ${requestScope['javax.servlet.forward.request_uri']}

    Maybe you are looking for something like: 

    <%= new UrlPathHelper().getOriginatingRequestUri(request) %>

    This is not that elegant but solved my problem.

    Try this:

    <%@ page import="javax.servlet.http.HttpUtils.*" %>
<%= javax.servlet.http.HttpUtils.getRequestURL(request) %>
