情人节后的 JSF PrimeFaces2.0 更完美了！
PrimeFaces是最早也最全面的支持JSF2.0的开源库，它显然走在了RichFaces，ICEfaces，MyFaces的前面，2月14日后对JSF2.0的支持更加的完善，增加了几个组件并修补了很多bug，受益于JavaEE6.0的新技术，我们现在可以零配置的在Netbeans6.8或新版本中开发PrimeFaces2.0应用了。
在这里只需要到 http://www.primefaces.org网站上下载其jar包并添加到项目classpath上即可，相当简单，我们看一下官方的一个使用Tree组建事件特性的完整例子(5分钟内搞定)：
1.在Netbeans下新建一JavaWeb工程，一切皆默认，并将primefaces-2.0.0.jar添加到类路径中，index页面代码如下
2.其托管bean代码如下
3.运行就ok了，可以很容易实现左边树导航，中间内容的经典应用。
