嵌入式jetty 9 classNotFound用于WebAppContext.doStart中的AnnotationConfiguration

我正在尝试设置一个嵌入式jetty 9实例，它从.war文件中获取注释 .

到目前为止它成功运行，例如GeoServer.war（通过将ExtractWars设置为True），但是当它获取包含带注释的servlet的WebChat.war时，我在AnnotationsConfiguration类上获得了一个ClassNotFound .

在示例战争中，我将'metadata-complete= 1515220 '添加到其web.xml中，另外我将下一位添加到jetty服务器

ContextHandlerCollection mHandlers = new ContextHandlerCollection();

  String mWebAppDir = ... ;
  WebAppProvider mAppProvider = new WebAppProvider();
  mAppProvider.setMonitoredDirName( mWebAppDir );
  mAppProvider.setDefaultsDescriptor( null );
  mAppProvider.setScanInterval(0);
  mAppProvider.setExtractWars(true);
  mAppProvider.setConfigurationClasses( new String[]{
    AnnotationConfiguration.class.toString(),
    WebInfConfiguration.class.toString(),
    PlusConfiguration.class.toString(),
    FragmentConfiguration.class.toString(),            
  });

  DeploymentManager mDeployMgr = new DeploymentManager();    
  mDeployMgr.addAppProvider( mAppProvider );
  mDeployMgr.setContexts( mHandlers );    

  /* Setup & Run server */
  mServer.addBean(mDeployMgr);
  mServer.setHandler(mHandlers);
  mServer.start();

我将所有Jetty9 jar（jetty-distribution-9.0.3.v20130506），包括jar 'websocket-core-9.0.0.M2.jar'添加到jetty服务器项目中 . IDE知道AnnotationConfiguration类，但是当jetty处理war文件时，它会带有：

希望得到如何解决类加载问题的线索..
