如何在tomcat 6上启用NIO/amosphere

Question

我正在tomcat 6上试用氛围，但只有长轮询才有效，而不是websocket。我在控制台输出中收到的消息是

 Tomcat failed to detect this is a Comet application because context.xml is missing or the Http11NioProtocol Connector is not enabled.

任何关于这方面的信息都将不胜感激，感谢

更新：修改web.xml和server.xml后，会出现错误消息，但聊天应用程序总是回到长轮询-我已经尝试了几种不同的.war部署websocket演示，它们的行为都是一样的。

我也试过Tomcat7，但它仍然使用长轮询。

当聊天客户端连接时

27/08/2012 10:47:57 AM org.apache.tomcat.util.net.NioSelectorPool getSharedSelector

信息：使用servlet写/读的共享选择器

当发送消息时

10:48:09.256 [http-8080-exec-2] DEBUG o.a.cpr.AsynchronousProcessor - Cancelling the connection for request AtmosphereRequest{ contextPath=/atmosphere-rest-chat servletPath=/chat pathInfo=null requestURI=/atmosphere-rest-chat/chat requestURL=http://mogwai:8080/atmosphere-rest-chat/chat destroyable=true}

在context.xml:中

<？xml版本="1.0"编码="UTF-8"？><上下文><Loader delegate="true"/><上下文>

在server.xml中：

<Connector connectionTimeout="20000" port="8080" 
           protocol="org.apache.coyote.http11.Http11NioProtocol" 
           redirectPort="8443"/>

确保在类路径中只定义了一个CometProcessor实现。如果catalina.jar已绑定，您可能需要将其从webpass中删除。有关更多信息，请参阅此线程：
