錯誤使用與就餐simphony

我想用java的WebSocket與就餐simphony，但它不工作，碼頭，當我得到以下錯誤：錯誤使用與就餐simphony

 
    java.lang.NoSuchMethodError: javax.servlet.http.HttpServletRequest.getServletContext()Ljavax/servlet/ServletContext;

     at java.lang.Thread.run(Thread.java:745)

有人能解釋我如何解決這個問題？謝謝

我測試了從互聯網上所採取的代碼，如果我不就餐simphony

我的服務器上運行它

 
    package webSocketTest; 

    import org.eclipse.jetty.server.Server; 
    import org.eclipse.jetty.websocket.server.WebSocketHandler; 
    import org.eclipse.jetty.websocket.servlet.WebSocketServletFactory; 

    public class WebSocketTest { 

     public static void main(String[] args) throws Exception { 
      Server server = new Server(8080); 
      WebSocketHandler wsHandler = new WebSocketHandler() { 
       @Override 
       public void configure(WebSocketServletFactory factory) { 
        factory.register(MyWebSocketHandler.class); 
       } 
      }; 
      server.setHandler(wsHandler); 
      server.start(); 
      server.join(); 
     } 
    }

 

    package webSocketTest; 

    import java.io.IOException; 
    import org.eclipse.jetty.websocket.api.Session; 
    import org.eclipse.jetty.websocket.api.annotations.OnWebSocketClose; 
    import org.eclipse.jetty.websocket.api.annotations.OnWebSocketConnect; 
    import org.eclipse.jetty.websocket.api.annotations.OnWebSocketError; 
    import org.eclipse.jetty.websocket.api.annotations.OnWebSocketMessage; 
    import org.eclipse.jetty.websocket.api.annotations.WebSocket; 

    @WebSocket 
    public class MyWebSocketHandler { 

     @OnWebSocketClose 
     public void onClose(int statusCode, String reason) { 
      System.out.println("Close: statusCode=" + statusCode + ", reason=" + reason); 
     } 

     @OnWebSocketError 
     public void onError(Throwable t) { 
      System.out.println("Error: " + t.getMessage()); 
     } 

     @OnWebSocketConnect 
     public void onConnect(Session session) { 
      System.out.println("Connect: " + session.getRemoteAddress().getAddress()); 
      try { 
       session.getRemote().sendString("Hello Webbrowser"); 
      } catch (IOException e) { 
       e.printStackTrace(); 
      } 
     } 

     @OnWebSocketMessage 
     public void onMessage(String message) { 
      System.out.println("Message: " + message); 
     } 
    }

另一個替代常規罐子的去除：事實上就餐Simphony 2.2使用servlet的API 2.4。不含有javax.servlet.http.HttpServletRequest.getServletContext（）方法。另一種解決方案是然後通過最近的javax servlet的API來替換由就餐Simphony默認使用的servlet的API JAR

我終於找到了解決方案它的工作原理。我刪除了所有的常規罐子它們是由存在於項目構建路徑默認情況下，它的工作原理。
