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 NIO framework has been designed to help developers to take advantage of the Java™ NIO API. Grizzly’s goal is to help developers to build scalable and robust servers using NIO as well as offering extended framework components: Web Framework (HTTP/S), WebSocket, Comet, and more!
