vaadin 7 websockets

Question

I am newbie to vaadin. I have few questions:

1. Does Vaadin 7 or later version supports websockets?

2. Does Vaadin has any other features like pushing data from server to client (e.g. websockets)?

Answer 1

Vaadin support Atmosphere, so google to get the plugin that will enable websockets.

Answer 2

Server push is the main feature coming with Vaadin 7.1 in a few weeks time. See the Roadmap for current status and the related blog post.

The most downloaded add-on for server push before Vaadin 7.1 is ICEPush but you can find other alternatives in the add-on directory as well.
