Jetty: ResourceHandler: Serve static content

ResourceHandler class is used to serve static content. Following example explains you, how to serve static content.

import org.eclipse.jetty.server.Handler;
import org.eclipse.jetty.server.Server;
import org.eclipse.jetty.server.handler.DefaultHandler;
import org.eclipse.jetty.server.handler.HandlerList;
import org.eclipse.jetty.server.handler.ResourceHandler;
import org.eclipse.jetty.server.handler.gzip.GzipHandler;

public class FileServer {
  public static void main(String[] args) throws Exception {
    Server server = new Server(8080);

    ResourceHandler resource_handler = new ResourceHandler();

    resource_handler.setDirectoriesListed(true);
    resource_handler.setResourceBase(".");

    GzipHandler gzip = new GzipHandler();
    HandlerList handlers = new HandlerList();
    handlers.setHandlers(new Handler[] { resource_handler,
        new DefaultHandler() });
    gzip.setHandler(handlers);
    server.setHandler(gzip);

    server.start();
    server.join();
  }
}

Run above application and hit the url ‘http://localhost:8080/’. 

Server server = new Server(8080);

Instantiate server, that listens at port 8080.

ResourceHandler resource_handler = new ResourceHandler();

Initialize ResourceHandler, it is used to serve static content.

GzipHandler gzip = new GzipHandler();

Initialize GzipHandler, used to send compressed responses.

HandlerList handlers = new HandlerList();

handlers.setHandlers(new Handler[] { resource_handler, new DefaultHandler() });

gzip.setHandler(handlers);

Above statements add resource_handler, DefultHandler to GzipHandler. DefaultHandler generates a good 404 response for any requests that do not match a static resource.
