[jetty-users] Question regarding Embedded Jetty and WebApp Deployment

["Srijith Kochunni" <ksrijith@xxxxxxxxxx>]

Hi All,

 

          I am new to this list and please pardon me, if this question has been previously answered. I did a lot of googling before I decided to post.

 

         I have previously used Jetty 6.1.15 and have recently upgraded to Jetty 9.2.12 and am struggling with the webapp deployment part of it. I have jetty bundles loaded in an OSGi runtime and am trying to start Jetty with a WebAppContext added to it. My code is similar to the examples seen  at http://www.eclipse.org/jetty/documentation/current/embedding-jetty.html#d0e19225. My code is as follows

 

        Server server = new Server(80);
       
        ServletContextHandler context = new ServletContextHandler(ServletContextHandler.SESSIONS);
        context.setContextPath("/");
        context.addServlet(new ServletHolder(new HelloServlet()),"/hello");
       
        ContextHandlerCollection contexts = new ContextHandlerCollection();
               
        WebAppContext webapp = new WebAppContext();
        webapp.setResourceBase(".");
        webapp.setDescriptor("WEB-INF/web.xml");
        webapp.setContextPath("/");
        webapp.setExtractWAR(true);
        webapp.setWar("E:\\jettyTest\\webapps\\testWebApp.war");
        contexts.setHandlers(new Handler[]{context, webapp});
       
        server.setHandler(contexts);
        server.start();

 

The server starts up fine, the servlet handler is also registered fine, but my webapp Context startup always fails with the following exception

I believe it is looking for some kind of default descriptor. I am not sure how to get this started without a default descriptor. Is that mandatory? Am I doing something wrong. Do kindly help.

 

Thanks,

Srijith.
