前段时间学习JSF过于激进，所以遇到好多并不是问题的问题，所以决定重头开始学习JSF。
买了本《JavaServer Faces 完全参考手册》巩固知识（讲得很不错，全面详细，翻译的也不错，比JSF in action 更注重基础）。使用的环境是Eclipse Jee版 ＋ JBoss tool，用起来感觉比MyEclipse好用多了（占用资源少，操作反应很快，UI操作很友好，推荐使用）。这些内容来自于以为业内前辈，他写的blog很有启发性，有兴趣的同仁可以阅读一下。地址：http://hi.baidu.com/jsfcn/blog/item/ffbf40fb60875767024f567a.html
现在开始说正题：最好的学习是有个简单的例子，一步一步的教你如何做。《参考手册》开篇的例子简单，不过很基础，也没用IDE。照着操作了一遍，代码当然不成问题，结果一运行就出了问题：
