//如果此处不使用try catch块，那么派发前的错误将直接显示在屏幕上

//把自己定义的类文件都放到library目录的Pw目录下，然后在配置文件中写入autoloadernamespaces.Pw = "Pw_"就可以自动加载了
//这里没有namespace前缀，所以要使用如下方法完成自动加载：
//$application->getAutoloader()->setFallbackAutoloader(true);
//Zend_Application_Module_Autoloader有一定的局限性，默认情况下他只能加载models, forms等系统定义的文件夹，自定义的不可以。
//所以此处application下只有controllers以及views文件夹，models下的DatabaseObject全部移至library
