linux jsp utf-8字符错误

将网页从window下迁至redhat下，报错："Page-encoding specified in XML prolog (UTF-8) is different from that specified in page directive (utf-8)"

从字面意思理解，应该是utf-8与UTF-8的区别，于是将所有页面字符都更改为"utf-8"。可错误依然出现。最终调试发现jsp页面代码[code]<%@ page language="java" contentType="text/html; charset=utf-8"
pageEncoding="utf-8"%>”[/code]多了一句pageEncoding="utf-8"，而这句代码是eclipse自动生成的。删除后一切正常。
