如何将GWT连接到CometD / Bayeux事件？ [英] How can I connect GWT to CometD/Bayeux events?

问题描述

我有一个GWT应用程序，它们定期需要更新屏幕，新的刻录项目进来时。我们还有一个CometD / Bayeux服务器发布的消息（对于不同的AJAX应用程序），我想在我的GWT中消费它们。

当然，我可以放入JavaScript，挂接Dojo，并在JavaScript层接收回调，从那里，通过JSNI将一个调用转换为GWT Java代码 - 但是除了非RESTful RPC之外，GWT中直接使用长推或异步调用似乎没有任何支持。

您如何整合GWT和Bayeux？

解决方案

问题最初发布在那里有一些进展：

• http://code.google.com/p/google-web-toolkit-incubator/wiki/ServerPushFAQ


• http://code.google.com/p/gwteventservice/


• http://code.google.com/p / gwt-comet /

I've got a GWT application, which periodically needs to update the screen with new tick items as they come in. We also have messages published by a CometD/Bayeux server (for a different AJAX application) and I'd like to consume them in my GWT.

Of course, I can drop into JavaScript, hook up Dojo, and receive callbacks in the JavaScript layer - and from there, route a call into GWT Java code via a JSNI - but there doesn't appear to be any support in GWT directly for using long push or async calls other than the non-RESTful RPC.

How have you integrated GWT and Bayeux?
