Java異步消息傳遞框架，Errai 2.0 發布

Errai是JBoss開發的一個基于GWT的框架，使用下一代WEB技術，用于構建富客戶端應用。該框架構建在ErraiBus基礎上，為客戶端與服務器的異步消息傳遞提供了一個真正統一的消息基礎設施。

經過幾個月的開發，對一些 API 進行了大幅的調整之后，Errai 團隊今天發布了 2.0 的正式版。該版本主要改進內容：

• Errai eliminates the need for boilerplate code and configuration in several areas, including entry points, remote services, UiBinder, and more.
• Errai brings some of parts of Java EE 6 to the browser: CDI (standardized IoC and eventing) and a typesafe JAX-RS client. A JPA 2.0 implementation is on the way in 2.1!
• Errai includes a simpler-to-use and more flexible marshalling and RPC system
• Errai provides a client-server message bus with bidirectional push messaging (much of the above is based on Errai's Bus, and you can choose to use the bus API directly in your code).
• Errai is guided by the belief not only that a uniform programming model across client and server is a big advantage, but that it's also advantageous to share significant parts of your code base between the client tier and the server tier
