Silverlight analog in Java environment

Is there any analog to Microsoft Silverlight in Java World? The requirement is to use native language and share some already written libraries while hosting in a web browser on client side. Silverlight is a grea开发者_高级运维t technology, but it doesn't work on Linux. Please don't remind me of Moonlight. Please don't suggest ActionScript as it's not Java.

Thanks.

JavaFX springs immediately to mind, which sort of hangs around in the Flash/Silverlight space. It's pretty immature, though, and not heavily used.

For a more general RCP platform, try Eclipse RCP.

You could look at GWT or Echo2
