Hi all,
This question has already been asked before, but the solutions found in
the archives don't seem to work properly.
I have a web site running on IIS and Tomcat 4.1.24 under the root
context, let's say http://www.mysite.com
When people access the URL, it automatically redirects to the context's
default page "index.html", making the http://www.mysite.com/index.html
URL to appear in the browser. I'd like to avoid this and only have
http://www.mysite.com in the location bar instead. BUT I only want this
behaviour for the default page only, NOT for other pages (f.ex.
http://www.mysite.com/info/home.htm should remain unchanged in the
location bar).
In the Tomcat list archives, some people mentioned about writing a
servlet which would forward the request to the appropriate page. Here's
what I've done :
1) I've added added this in the web.xml :
<servlet>
<servlet-name>indexredirect</servlet-name>
<servlet-class>test.servlets.IndexRedirect</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>indexredirect</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
2) I've created the IndexRedirect servlet and added it in the
WEB-INF/classes/etc... directory, whose doGet() method looks like this :
public void doGet(HttpServletRequest request, HttpServletResponse
response) throws ServletException, IOException {
response.setContentType(CONTENT_TYPE);
String requestUri = request.getRequestURI(),
contextPath = request.getContextPath(),
requestedPage = "";
requestedPage = requestUri.replaceFirst(contextPath, ""); //
request.getServletPath() seems to do it too, but doesn't always work ?
System.out.println("requestedPage : "+requestedPage);
if (requestedPage.equals("/")) {
System.out.println("DEFAULT Forwarding request to index.html
!");
RequestDispatcher reqDispatcher =
request.getRequestDispatcher(response.encodeURL("index.html"));
reqDispatcher.forward(request, response);
}
// Commented out because redirecting to the requested page starts an
infinite loop !!!
/* else {
System.out.println("Forward request to "+requestedPage+"...");
RequestDispatcher reqDispatcher =
request.getRequestDispatcher(response.encodeURL(requestedPage));
reqDispatcher.forward(request, response);
}*/
}
After testing the http://www.mysite.com/ URL, the page redirects to
index.html the first time, which is fine. But then, I don't know why but
the servlet is called again, detects that the requested URL is
http://www.mysite.com/index.html now, and would go to the "else"
statement (here commented out), and thus forward the request to
index.html again !! Infinite loop...
My questions are :
- I don't understand why the servlet is called whenever the request URI
is, although the <url-pattern> tag in web.xml is defined as "/" (so the
servlet should only be called when the context's root page is requested,
i.e. http://www.mysite.com/ ?).
- How can I have this thing done ? Is there something I've forgotten
here ?
Thanks a lot for your help, this problem is really puzzling me...
Note : I'm not using Apache, so mod_rewrite is not an option for me.
Best regards
Alain Hertenstein
