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,该实例从.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),但是当它选择包含带注释的servlet的WebChat.war时,我在 AnnotationsConfiguration 类上得到 ClassNotFound

在示例战中,我将'metadata-complete =“false”'添加到其web.xml中,同时我将下一位添加到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();

我在Jetty服务器项目中添加了所有Jetty9 jar(jetty-distribution-9.0.3.v20130506),包括jar'websocket-core-9.0.0.M2.jar'。 IDE知道 AnnotationConfiguration 类,但是当jetty处理war文件时,它会附带:

希望得到如何解决类加载问题的线索。

感谢您查看我的问题。

我发现了问题;

我在端口8443上运行jetty服务器 ,而不是在8080上运行。但是使用

初始化了webchat.html文件
$(document).ready(
function() {
      ws = new WebSocket("ws://localhost:8443/WebChat/map");

但它应该是WSS协议,因为它通过8443安全。即

$(document).ready(
function() {
      ws = new WebSocket("wss://localhost:8443/WebChat/map");

原来它无法将 setConfigurationClasses 设置为

  mAppProvider.setConfigurationClasses( new String[]{
    AnnotationConfiguration.class.toString(),
    WebInfConfiguration.class.toString(),
    PlusConfiguration.class.toString(),
    FragmentConfiguration.class.toString(),            
  });

希望有人对此有所帮助。
