Redirect from ROOT

Question

I am trying to redirect to the welcome page from ROOT. When www.mydomain.com is called from a browser, the servlet inside ROOT should redirect to another web page in webapps/welcome/index.jsp
What I did:
com.index.Redirect
public class Redirect extends HttpServlet
     private final String url = "welcome/index.jsp";
     public void doGet(HttpServletRequest request, HttpServletResponse response) throws IOException, ServletException
          response.sendRedirect(url);
}web.xml:
<servlet>
    <servlet-name>Index</servlet-name>
    <servlet-class>com.index.Redirect</servlet-class>
  </servlet>
  <servlet-mapping>
    <servlet-name>Index</servlet-name>
    <url-pattern>/index</url-pattern>
  </servlet-mapping>What I got: The requested resource (/) is not available
What am I missing? Thanks

Answer 1

"/" is not the same as "/index". The mapping from / to /index is done on the server side, not the client, so you can't assume that every hit will start with at least /index. Also if I recall correctly / has a special meaning in servlet environment configurations and may not behave as expected.
Generally (or always?) web servers and I believe servlet containers have a special configuration option to identify a home page, so be careful that you're not reinventing the wheel here.
