Here is what I would like to do:
public class RewriteServletDispatcher extends ServletDispatcher {
public void service(HttpServletRequest request, HttpServletResponse response) throws ServletException {
// extract the article id to retreive
String pathInfo = request.getPathInfo();
String articleID = pathInfo.substring(1, pathInfo.length());
// alter the original request so that WW handles it
// the request could be now something like "/showArticle.action?article=<articleID>"
???
}
}
As show above, even though I am able to extract the relevant information (the article ID), I am not able to tell the ServletDispatcher that instead of using the action built from the request path I would like to use my own path (that would be a "regular" WW action name with my article id as a parameter).
So ServletDispatcher does not seem to offer much compared to a custom Servlet (I mean in the use case of course :-)).
If ServletDispatcher was "refactored" a little bit so that the main work would be done in a method independant of the ServletRequest this would probably help. I am thinking about something like this:
public class ServletDispatcher extends HttpServlet {
public void service(HttpServletRequest request, HttpServletResponse response) throws ServletException {
// extract the relevant information from the HttpServletRequest object
handleRequest(extractPath, response);
}
protected void handleRequest(String requestPath, HttpServletResponse response) throws ServletException {
}
// other methods omitted for brief
}
This would allow developers to extend ServletDispatcher and still be able to implement any URL mapping policy they'd like to use.
I would definitely prefer something better than my own servlet with a "copy&paste" from ServletDispatcher's code.
Any suggestion?
BTW, I think this kind of servlet should be included in WW. This would allow pretty URL (this is in fact the main purpose I'm trying to reach).

Subject: [OS-webwork] Advanced URL mapping?
Hi,
I would like to be able to map some URL to some actions where part of the URL is transformed as a parameter to the action.
For example, I would like the URL "http://myhost.com/article/XYZ"; to be rendered as the view of the action "showArticle" with the parameter "articleID" set to "XYZ".
I could possibly do such a thing using Apache (and especially mod_rewrite) as a proxy to the web server, but I would like to handle it at the Servlet level.
I am wondering what is the best way to do it... Should I extend WW default ServletDispatcher?
Thanks in advance,
J�r�me.
