NIO connecter does not work after startup normally

?Hi there,

First here is the output of the startup:

Notice that the Http11NioProtocol started on port 8080. Now when I try to write my own @WebServlet, 
OR run cometd demo from cometd.org, the same errors happened:

Sorry.
I don't know about the asynchronous mechanism the servlet 3.0 introduces.
You may can read servlet 3.0 spec?

?JDK 1.6 update 22. Tomcat 7.0.4. Windows 7 Ultimate 64. I have downloaded 
the native lib and therefore the nio connecter info seems correct. Anything 
else missing? Thank you.
