有没有人知道gwt中的服务器推送/共享技术

Question

我需要以任意方式将一些数据从服务器推送到客户端，我的意思是当有数据时它将使用commet技术推送客户端小部件中的数据，任何想法如何以及从何处开始。

Answer 1

There are many libraries for GWT but here are a few:
http://code.google.com/p/gwteventservice/
http://code.google.com/p/gwt-comet/
http://code.google.com/p/rocket-gwt/wiki/Comet
http://www.jboss.org/errai
http://code.google.com/p/dwr4gwt/

Answer 2

I played around with many of these libraries and found that GWTEventService works quite nicely, I have been using it for some time for a web based chat client that I wrote. It is also very easy to get up and running so that might be a good one to start with.

Answer 3

这是一个关于服务器推送技术的好文档。
