body: <p>I have a java app that runs jetty:</p>
  
  <pre><code>public class ServerRunner {
  
      private final static org.apache.log4j.Logger logger = LoggingUtils.getLogger();
  
      public static void main(String[] args) throws Exception {
          PromptoConfig.s.initLog();
  
  
          final int port = 8082;
  
          final Server jettyServer = new Server(port);
          final HandlerCollection handlers = new HandlerCollection();
  
          // Creating the first web application context
          final WebAppContext webappContext = new WebAppContext();
  
          System.out.println("===== PromptoConfig.s.RESOURCES_BASE " + PromptoConfig.s.RESOURCES_BASE);
          webappContext.setResourceBase(PromptoConfig.s.RESOURCES_BASE);
          webappContext.setContextPath("/");
  
          System.out.println("===== PromptoConfig.s.WEB_XML_PATH " + PromptoConfig.s.WEB_XML_PATH);
          webappContext.setDefaultsDescriptor(PromptoConfig.s.WEB_XML_PATH);
  //        webappContext.setTempDirectory(new File(temp));
  
  
          DBSQLConfig.s().DB = com.waze.prompto.config.DBSQLConfig.s.DB;
  
  
          webappContext.setExtractWAR(false);
          handlers.addHandler(webappContext);
  
          // Adding the handlers to the server.
          jettyServer.setHandler(handlers);
  
          try {
              jettyServer.start();
              jettyServer.join();
          } catch (Exception ex) {
              logger.error("failed to init jetty server", ex);
          } finally {
              jettyServer.destroy();
          }
      }
  }
