从浏览器访问 http://localhost:8080/project/faces/
访问到了地index.jsp页面，点击了页面的OK按钮页面有了刷新动作，按faces-config.xml文件的配置，
本该“跳转”到welcome.jsp页面，可却没跳转。
工程里本来应有Bean的（其实也有），可我连Bean这步都没用了，但还是有问题，请大家看看，以后也
给有同样问题的朋友一个参考。
谢谢。
[解决办法]
<h:commandButton value= "ok " action= "login "/>
写得有问题,必须有managed bean,参考
<h:commandButton value= "ok " action= "#{InfoBean.login} "/>
