我有一个运行在Tomcat7上的Java应用程序，它使用了Atmosphere Framework。大气是一个Websocket框架。我使用Atmosphere Sample Chat的示例应用程序。 我的问题是，我没有得到连接器以及运行我的Websocket Atmosphere应用程序的正确配置。如何配置Tomcat和HAProxy以使用WebSocket Framework大气？
的问题我已经是：
- 我希望如何配置我的HAProxy的？
- 如何配置我的Tomcat服务器？
- 如何为APR和NIO连接器配置Tomcat？
- 我是否必须在我的应用程序（即我的web.xml）中更改某些内容？
- 如何解决下面的错误？
这是我HAProxy的配置：
defaults
mode http
log global
option httplog
option http-server-close
option dontlognull
option redispatch
option contstats
retries 3
backlog 10000
timeout client 25s
timeout connect 5s
timeout server 25s
# timeout tunnel available in ALOHA 5.5 or HAProxy 1.5-dev10 and higher
# timeout tunnel 3600s
timeout http-keep-alive 1s
timeout http-request 15s
timeout queue 30s
timeout tarpit 60s
default-server inter 3s rise 2 fall 3
option forwardfor
frontend ft_web
bind *:80 name http
maxconn 60000
acl host_testhostdev hdr(host) -i www.testhost.com
use_backend apache-8080 if host_testhostdev
default_backend apache-8080
backend apache-8080
balance roundrobin
server websrv1 localhost:8080 maxconn 8000 weight 10 cookie websrv1 check
的的web.xml一部分，我的Servlet的气氛：
<async-supported>true</async-supported>
<init-param>
<param-name>org.atmosphere.useNative</param-name>
<param-value>true</param-value>
</init-param>
<init-param>

</init-param>
<init-param>

<init-param>
<param-name>org.atmosphere.cpr.broadcasterCacheClass</param-name>
<param-value>org.atmosphere.cache.UUIDBroadcasterCache</param-value>
</init-param>
我在Tomcat的server.xml中改变什么
!--
<Connector port="8080" protocol="HTTP/1.1"
connectionTimeout="20000"
redirectPort="8443" />
-->
<Connector port="8080" protocol="org.apache.coyote.http11.Http11NioProtocol" redirectPort="8443"/>
这些都是错误我得到：
和

而这一次，如果我访问我的IE8和IE9应用：
