Redirect All URL to return index.html in App Engine Java servlet

The web application uses Java Restlet in the backend running on Google App Engine.

I want to return index.html for all url (/*).

Here, I don't want to use response.redirect, I mean, client should not aware of redirection.

I used following code in web.xml.

  <servlet>
    <servlet-name>RestletServlet</servlet-name>
    <servlet-class>org.restlet.ext.servlet.ServerServlet</servlet-class>
    <init-param>
        <param-name>org.restlet.application</param-name>
        <param-value>com.post.PostApplication</param-value>
    </init-param>
</servlet>
<servlet-mapping>
    <servlet-name>RestletServlet</servlet-name>
    <url-pattern>/api/v1/*</url-pattern>
</servlet-mapping>

 <servlet>
    <servlet-name>StartPageServlet1</servlet-name>
    <jsp-file>/client/index.html</jsp-file>  
</servlet>
<servlet-mapping>
    <servlet-name>StartPageServlet1</servlet-name>
    <url-pattern>/*</url-pattern>
</servlet-mapping>

It served all /api/v1 request with Restlet. It works fine. But /* should always return index.html. How do I do it?

You can plug in a filter and inspect the Request URI and, based on it, decide whether or not to forward it to your home page:

RequestDispatcher rd = request.getRequestDispatcher("/index.html"); rd.forward(request, response);

You can use interceptor. For each incoming request, you can set the target page as your index.html

You want to serve static files only (no dynamic file, JSP file).

You may try removing all the servlets from your web.xml and use the welcome-file-list feature:

<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE web-app PUBLIC
 "-//Oracle Corporation//DTD Web Application 2.3//EN"
 "http://java.sun.com/dtd/web-app_2_3.dtd">

<web-app xmlns="http://java.sun.com/xml/ns/javaee" version="2.5">

    <welcome-file-list>
        <welcome-file>index.html</welcome-file>
    </welcome-file-list>

</web-app>

Have a try and let me know if this works.
