Is it possible to store static resources inside the uber jar created with an embedded jetty server project? I created this simple project based on an answer by @JoakimErdfelt Serving static files from alternate path in embedded Jetty. I kept the default-servlet to serve the static content, but I switched the dynamic-servlet for a restful jersey-servlet and it works great as long as the jar is in the same directory as the index.html. I would like to be able to embed the index.html file inside the jar but when I issue "mvn clean install" the webapp directory doesn't appear in the jar that's built. I think the pom.xml needs an entry but I don't know what it is and I think the jetty.java needs to change to find the index.html inside the embedded webapp directory. Here is the current directory structure.

public class Jetty {
public static void main(String[] args) throws Exception {
System.setProperty("org.eclipse.jetty.LEVEL","INFO");
Server server = new Server();
ServerConnector connector = new ServerConnector(server);
connector.setPort(8080);
server.addConnector(connector);
// Setup the basic appliation "context" for this application at "/"
// This is also known as the handler tree (in jetty speak)
ServletContextHandler context = new ServletContextHandler(ServletContextHandler.SESSIONS);
context.setContextPath("/");
server.setHandler(context);
// The filesystem paths we will map
String homePath = System.getProperty("user.home");
String pwdPath = System.getProperty("user.dir");
// add a simple Servlet at "dynamic/*"
ServletHolder holderDynamic = new ServletHolder(
"dynamic", org.glassfish.jersey.servlet.ServletContainer.class);
context.addServlet(holderDynamic, "/dynamic/*");
holderDynamic.setInitOrder(0);
// Tells the Jersey Servlet which REST service/class to load.
holderDynamic.setInitParameter(
"jersey.config.server.provider.classnames",
Rest.class.getCanonicalName());
// add special pathspec of "/home/" content mapped to the homePath
ServletHolder holderHome = new ServletHolder(
"static-home", DefaultServlet.class);
holderHome.setInitParameter("resourceBase",homePath);
holderHome.setInitParameter("dirAllowed","true");
holderHome.setInitParameter("pathInfoOnly","true");
context.addServlet(holderHome,"/home/*");
// Lastly, the default servlet for root content (always needed, to satisfy servlet spec)
// It is important that this is last.
ServletHolder holderPwd = new ServletHolder(
"default", DefaultServlet.class);
holderPwd.setInitParameter("resourceBase",pwdPath);
holderPwd.setInitParameter("dirAllowed","true");
context.addServlet(holderPwd,"/");
try
{
server.start();
server.dump(System.err);
server.join();
}

t.printStackTrace(System.err);
