Re: [jetty-users] Jetty 8.1 annotations

[Andreas Schöneck <as.maps@xxxxxxxxx>]

Generally speaking, I bet Jetty won't do the scanning for annotations for you unless you explicitly advise it to.

I came across a class org.eclipse.jetty.annotations.AnnotationConfiguration which might be a good starting point for further research.

I am using Jetty in an embedded fashion and am having difficulties with
the annotations for
Servlet 3.0.

My server code is such:

       WebAppContext context = new WebAppContext();

       context.setConfigurations( new
org.eclipse.jetty.webapp.Configuration[] {
               new AnnotationConfiguration(), new WebXmlConfiguration(),
               new WebInfConfiguration(), new TagLibConfiguration(),
               new PlusConfiguration(), new MetaInfConfiguration(),
               new FragmentConfiguration(), new EnvConfiguration() });

       context.setDescriptor("webapp/WEB-INF/web.xml");
       context.setResourceBase("webapp");
       context.setContextPath("/");
       context.setParentLoaderPriority(true);
       context.setSessionHandler(ServiceManager.getSessionService().getSessionHandler());


       ContextHandlerCollection contexts = new ContextHandlerCollection();
       contexts.setHandlers(new Handler[]{context});

       server.setHandler(contexts);


I have a servlet defined as such:

@WebServlet(name="commandServlet", urlPatterns = {"/commander"},
asyncSupported=true)
public class OCSServlet extends HttpServlet
{

   /**
    *
    */
   private static final long serialVersionUID = 531143127788829466L;

   /* (non-Javadoc)
    * @see
javax.servlet.http.HttpServlet#doPost(javax.servlet.http.HttpServletRequest,
javax.servlet.http.HttpServletResponse)
    */
   @Override

   protected void doGet(HttpServletRequest req, HttpServletResponse resp)
           throws ServletException, IOException
   {
       AsyncContext ctx = req.startAsync(req, resp);
       /** ... do something ... **/
   }

}

Note that I have set a breakpoint on the doGet() method.


I have made sure that the appropriate jar files are in the classpath.
However,
when I go to the http://localhost:8080/commander url, my servlet never gets
invoked, i.e. the debugger never stops at my breakpoint and the browser
returns
HTTP ERROR 404

Problem accessing /commander. Reason:

   Not Found
Powered by Jetty://

Is there anything specific that I must do for the annotated servlet
classes to be
loaded?  Do the class files have to be under the webapp/classes directory?
 If I
I specify the context, like

       ServletContextHandler ctx = new
ServletContextHandler(ServletContextHandler.SESSIONS);
       ctx.addServlet(OCSServlet.class, "/commander");

then things are fine, but of course, this isn't loaded by annotation and
my servlet class
is loaded from my classpath.

Thank you all for the help.

Jeff
