> With the jboss cli I can read the proxies info like this:

>
> I looked for the ModClusterListener MBean methods and properties in Tomcat 7. I found this method in ModClusterListener:

> @Override
> public Map<InetSocketAddress, String> getProxyInfo() {

> The problem is that I found no proxyInfo method or attribute at the ModClusterListener MBean.
