Netty inside Tomcat (or Jetty) ?

[Trustin Lee (이희승)]

Hi Elemer,

Netty has been designed to run in various environments.  If should
work fine with a web application server, applet, android needless to
say all J2SE environments.  I see no problem with embedding Netty
inside a web application server.
