Serving a GWT Application with an Embedded Jetty Server

Posted Saturday, March 27, 2010

For a new project I am interested in starting, I want to serve a GWT application with an embedded Jetty server. I wasn’t sure how to go about doing so, but it turns out it’s easier than I could ever have expected! Check it out below.

package net.binarymuse.EmbeddedGwt; 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(); } }View Gist for EmbeddedGwt.java on GitHub

You do, of course, need the Jetty jars (I used the ones from the ‘lib’ folder in the Jetty distribution) in your classpath.
