Sorry, I should have explained better what I am doing.
My controller Servlet is mapped to /services/*
All requests for JSP pages go through the controller, via action mappings. The actions have paths like:
/usecase/view_edit_page /usecase/save_existing_record /usecase/view_add_page /usecase/add_new_record
So the full links look like:
<context>/services/usecase/view_edit_page
meanhwhile other resources have paths like:
<context>/images/some_image.gif
This keeps other resources out of the scope of the controller (and perhaps into the scope of some other servlet). Also, direct JSP access is prohibited.
So in places where I am building hyperlinks (within JSPs), I need to get "/services" into each link, in front of the action URI, but behind the context. And I want to do this in a portable way (in case the Servlet mapping changes).
So the idea is to put something like <html:rewrite page="${controller_path}<action_URI_here>"> which literally would be "/services" + "/usecase/action" or "/services/usecase/action". Using the "page" attribute to the tag makes it come out right ("/context/services/usecase/action").
(When I say "usecase" here I really should say "collection of usecases" or "function group" to be more accurate).
I would be interested in hearing other mapping strategies. For now I'm making sure the JSP can call a method or access a variable that returns "/services".

Are you mapping the jsp to /services in the web.xml? if you do, getServletPath should return the path you are looking for.
<servlet> <servlet-name>jsp</servlet-name> <jsp-file>/usecase/page.jsp</jsp-file> </servlet>
<servlet-mapping> <servlet-name>jsp</servlet-name> <url-pattern>/services</url-pattern> </servlet-mapping>

Hmm I must be doing something wrong. That's giving me the same value as Erez's example. Strange, I would have expected it to give me "/services". I wonder how I am causing it to give me "/usecase/page.jsp".

Hi Erik,
This one worked for me:
<c:set var="v"> <%= request.getServletPath() %> </c:set>
<c:out value="${v}"/> <bean:write name="v"/>
HTH,

How can I set a variable (I assume with c:set) that will hold the value
of request.getServletPath, so that I can use it in el tags?
Thanks, Erik
