java.net - Grizzly

Writing scalable server applications in the Java™ programming language has always been difficult. Before the advent of the Java New I/O API (NIO), thread management issues made it impossible for a server to scale to thousands of users. The Grizzly framework has been designed to help developers to take advantage of the Java™ NIO API. Originally developed under the GlassFish umbrella, the framework is now available as a standalone project. Grizzly goals is to help developers to build scalable and robust servers using NIO.

Grizzly is part of the GlassFish community.
