Jetty and GWT (Google Web Toolkit) - gwt

Question

As I understand it, GWT uses an embedded Jetty server. Can
anyone please tell me where I can find the Jetty .xml configuration files
used by GWT? I have a webapp which makes uses of Jetty's
ContinuationFilter and ProxyServlet. The app works fine under GWT but
fails when run in a separate Jetty instance outside of GWT. If I can
replicate the GWT Jetty config then I think I'll be okay.
Edit for more info:
My webapp's web.xml reads as follows:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE web-app
PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
"http://java.sun.com/dtd/web-app_2_3.dtd">

<url-pattern>/bugzilla/*</url-pattern>
</filter-mapping>
<!-- Servlets -->

</servlet-mapping>
<!-- Default page to serve -->
<welcome-file-list>

</welcome-file-list>
</web-app>
and the link to my Bugzilla installation is in this form:
com.google.gwt.user.client.ui.Frame bugFrame = new Frame("/bugzilla/");
Running under Jetty 6.1.26, I get this output:

Answer 1

there is no jetty.xml. GWT sets up the Server programmatically.
You can find the setup in
com.google.gwt.dev.shell.jetty.JettyLauncher
contained in the gwt-dev.jar

Answer 2

See: Serving a GWT Application with an Embedded Jetty Server by Brandon Tilley (code extract shown below). He seems to have achieved it quite seamlessly, a process which I will be confirming myself tomorrow.
import org.eclipse.jetty.server.Server;
import org.eclipse.jetty.util.thread.QueuedThreadPool;
import org.eclipse.jetty.webapp.WebAppContext;
public class EmbeddedGwt {
public static void main(String[] args) throws Throwable {
// Create an embedded Jetty server on port 8080
Server server = new Server(8080);
// Create a handler for processing our GWT app
WebAppContext handler = new WebAppContext();
handler.setContextPath("/");
handler.setWar("./apps/GwtApplication.war");
// If your app isn't packaged into a WAR, you can do this instead
WebAppContext altHandler = new WebAppContext();
altHandler.setResourceBase("./apps/GwtApplication");
altHandler.setDescriptor("./apps/GwtApplication/WEB-INF/web.xml");
altHandler.setContextPath("/");
altHandler.setParentLoaderPriority(true);
// Add it to the server
server.setHandler(handler);
// Other misc. options
server.setThreadPool(new QueuedThreadPool(20));
// And start it up
server.start();
server.join();
}
}
