Hi I try to run websocket on jetty-distribution-9.2.5.v20141112.

here the code :

+-----------------------

package com.kiwi;

import java.io.IOException;

import javax.websocket.OnMessage;

import javax.websocket.Session;

import javax.websocket.server.ServerEndpoint;

@ServerEndpoint("/echo")

public class EchoEndPoint 

{

@OnMessage

public void onMessage(Session session, String message)

{

try {

for (Session sess : session.getOpenSessions()) {

           if (sess.isOpen())

              sess.getBasicRemote().sendText(message);

        }

} catch (IOException e) {

e.printStackTrace();

}

}

}

+---------------------------------

what i really do is, package it as war file, and put in the webapps, then run with 

java -jar C:\jetty-distribution-9.2.5.v20141112\start.jar jetty.base=C:\jetty jetty.home=C:\jetty-distribution-9.2.5.v20141112 --a

dd-to-start=deploy,http,jvm,websocket

then 

java -jar C:\jetty-distribution-9.2.5.v20141112\start.jar

however, i get the exception with start the server: 

2014-11-15 02:27:04.113:WARN:oejut.QueuedThreadPool:qtp300837073-16:

        at org.eclipse.jetty.annotations.AnnotationParser.scanClass(AnnotationPa

rser.java:974)

......

my --list-config contain this :

Jetty Active XMLs:

------------------

 ${jetty.home}\etc\jetty.xml

 ${jetty.home}\etc\jetty-http.xml

 ${jetty.home}\etc\jetty-deploy.xml

 ${jetty.home}\etc\jetty-plus.xml

 ${jetty.home}\etc\jetty-annotations.xml

I can run in tomcat 8,0.14 with no issue, do I forget to configure something ?
