Re: [jetty-users] jersey to jsp different welcome file served on different platform
Thank you I will check the documentation.

In the meantime I have found that on the heroku website,
following the git commands in the documentation for uploading, 
https://lit-savannah-55019.herokuapp.com/
The contents of the index.html file  is served.

meanwhile   
mvn jetty:run
localhost:8080
the contents of the servlet are served.
That is very strange !

Previously on the heroku website when I served index.jsp
there was an error message saying JSP is not configured.
Could this behaviour be an indication that somehow  two different versions of jetty are running on different platforms. 


<!--  index.html -->
<html><body>
<h2>Jersey RESTful Web Application!</h2>

<p>contents of index.html </p>
</body></html>


@WebServlet(name="indexServlet", urlPatterns={"index.html"})
public class IndexServlet extends HttpServlet {

private static final long serialVersionUID = 1L;
    protected void doGet(HttpServletRequest request, HttpServletResponse response)
                            throws ServletException, IOException {
           
        response.setContentType("text/html");
        PrintWriter out=response.getWriter();            
        out.print("<html><body>");
        out.print("<h2>Jersey RESTful Web Application!</h2>");
        out.print("<p><a href="" resource</a>");
        out.print("<p>Visit <a href="" href="http://jersey.java.net/" style="text-decoration-line:none;color:rgb(66,133,244)">http://jersey.java.net> Project Jersey website</a> </p>");
        out.print("more information on Jersey!");
        out.print("<p> contents of servlet Indexservlet </p>");
        out.print("</body></html>");
    }
}

You're using a servlet to serve a welcome file instead of serving a static file. There is some ambiguity in the servlet spec around serving of welcome files, and jetty's default mode looks for a static resource. There are other configuration modes that will let you serve from the servlet without any associated static resource  - I think it's "exact" mode on the DefaultServlet, but check the jetty doco for the correct setting:

Something rather strange and unexpected just happened.

I put back the index.html file and now the contents of the java servlet class is being published to the browser.

The contents of index.html file is being overridden

Even a completely empty files called index.html does the trick.
