With the recent release of Async HTTP Client (AHC) 1.7.0, Ryan has details on how this impacts Grizzly to essentially provide support for WebSocket clients.
Ryan covers the new
grizzly-http-client Maven artifact for AHC and introduces
WebSocket interfaces for WebSocket support with a short but complete working sample.
With this release, Grizzly now provides support for both sides of the WebSocket wire.
Both GlassFish 3.1.2 and of course 4.0 will offer support for the final version of server-side WebSocket. if you're eager to use the technology in your application, then you should try out recent builds of 3.1.2 and let us know how things work for you.
