JBoss宣布JSR-299（Web Beans）的参考实现第一个Alpha 版发布了。参考实现主要是为了说明规范是可以实现和进行实践。她允许人们评估该技术并且研读规范。
为了对Web Beans有一个总体的认识，规范的领导者Gavin 写了一个包含五部分的系列内容：
* Part I - 介绍 Web Beans
* Part II - 注入，绑定注解和组件类型
* Part III - 使用XML声明组件
* Part IV - 范围、上下文、解析方法
* Part V - 拦截器和事件
还有Gavin 和Pete写的参考手册帮助你进行学习。然后你可以下载AS 5.0.0 和 the Web Beans Alpha

JBoss is responsible for producing the Reference Implementation of JSR-299 (aka Web Beans) and Pete Muir(the RI lead) has just announced that the first Alpha release is available. Reference Implementations are useful in that they demonstrate that the specification is practical and can actually be implemented; it also allows people to evaluate the technology (ie. write some code) vs. just read the specification.
For an overview of Web Beans, Gavin (spec. lead) has written a five part series :
* Part I - Introducing Web Beans
* Part II - Injection, binding annotations and component types
* Part III - Declaring components using XML
* Part IV - Scopes, contexts and resolver methods
* Part V - Interceptors and events
There’s also the new Reference Guide written by Gavin and Pete to get you up to speed. Then you’re ready to download AS 5.0.0 and the Web Beans Alpha.
