　　-----------------------------------
　　原因：页面有空引用.
　　1.不能够访问外网,导致根本引用不到文件。（检查是否是文件引用问题，若是可将引进的文件下载到应用下,相对路径引用）。
　　2.引用的js/css等文件中获取页面元素，然而页面元素不存在。引起org.apache.jasper.JasperException 可通过F12看是否由文件引起。（去掉文件中多余的代码,或者页面删除多余的js/css等文件。）
　　3.缺少jasper-compiler.jar包(免费下载地址:http://zhidao.baidu.com/share/e57adff426a68646cc2dfde9f428feee.html)
