Javascript 使用Apache Vysper执行WebSocket握手时出现问题

我在成功握手时遇到问题。无论是独立运行Vysper还是嵌入简单Java服务器（我自己制作的，或者是预打包的示例之一），我在尝试从JavaScript客户端（我自己的或者是预打包的示例之一）连接时都会遇到相同的错误情况。返回的错误是HTTP 405响应，在Chrome的控制台中报告为“意外响应代码：405”

独立服务器的配置：

“spring config.xml”添加了以下内容：

    <bean id="websocketEndpoint" class="org.apache.vysper.xmpp.extension.websockets.WebSocketEndpoint"> 
        <property name="port" value="8080" /> 
        <property name="contextPath" value="/ws" /> 
    </bean> 

在客户端的Chrome控制台中：

  Unexpected response code: 405 
  Event {clipboardData: undefined, cancelBubble: false, returnValue: true, srcElement: WebSocket, defaultPrevented: false…} 
  CloseEvent {reason: "", code: 1006, wasClean: false, clipboardData: undefined, cancelBubble: false…} 

对如何进行有什么建议吗
