What's the difference between Jetty and Netty?

Question

What is the main difference between Jetty and Netty?

Netty is part of Jboss, but is it the default web server container?

Does Netty support Servlets 3.0?

Answer 1

Jetty is a lightweight servlet container, easy to embed within a java application, there is an easy to use jetty client also.

Netty is an asynchronous event-driven network application framework. You can write your own servlet container or http client app with help of the Netty framework for example.

Edit:

Forgot to mention that Jetty 8 and Apache Tomcat 7 support servlet 3.0 spec, but netty doesn't. Because it's not a servlet container.
