奇怪的文件编码引起的问题
我的Tomcat6.0是不是出错了哦?我新建了一个默认的MyJsp.jsp文件,文件中的代码为
<%@   page   language= "java "   import= "java.util.* "   pageEncoding= "utf-8 "%>
<%
String   path   =   request.getContextPath();
String   basePath   =   request.getScheme()+ ":// "+request.getServerName()+ ": "+request.getServerPort()+path+ "/ ";
%>

<!DOCTYPE   HTML   PUBLIC   "-//W3C//DTD   HTML   4.01   Transitional//EN ">
<html>
    <head>
        <base   href= " <%=basePath%> ">
       
        <title> My   JSP   'MyJsp.jsp '   starting   page </title>
       
<meta   http-equiv= "pragma "   content= "no-cache ">
<meta   http-equiv= "cache-control "   content= "no-cache ">
<meta   http-equiv= "expires "   content= "0 ">        
<meta   http-equiv= "keywords "   content= "keyword1,keyword2,keyword3 ">
<meta   http-equiv= "description "   content= "This   is   my   page ">
<!--
<link   rel= "stylesheet "   type= "text/css "   href= "styles.css ">
-->

    </head>
   
    <body>
        This   is   my   JSP   page.   <br>
    </body>
</html>

运行它不出错..         大家注意MyJsp.jsps头部的pageEncoding= "utf-8 "%> 哦


可是当我运行我的另一个jsp文件,Tomcat就出错说:
/admin/admin_login.jsp(1,2)   Page-encoding   specified   in   XML   prolog   (UTF-8)   is   different   from   that   specified   in   page   directive   (utf-8)
这意思大家都明白吧,就是说文件编码写错了一点.

我的admin_login.jsp文件的代码如下:
<%@   page   language= "java "   import= "java.util.* "   pageEncoding= "utf-8 "%>
<%@   taglib   uri= "http://jakarta.apache.org/struts/tags-bean "   prefix= "bean "%>  
<%@   taglib   uri= "http://jakarta.apache.org/struts/tags-html "   prefix= "html "%>
 
<html>  
<head>
<title> JSP   for   ManagerLoginForm   form </title>
</head>
<body>
<html:form   action= "/managerLogin ">
用户名称   :   <html:text   property= "username "/> <html:errors   property= "username "/> <br/>
用户密码   :   <html:password   property= "password "/> <html:errors   property= "password "/> <br/>
<html:submit/> <html:cancel/>
</html:form> <%=request.getAttribute( "loginError ")%>
</body>
</html>

你们仔细地看一下,MyJsp.jsp和admin_login.jsp头部代码,也就是文件的第一行代码一模一样,可是我运行MyJsp.jsp就是不出错,而运行admin_login.jsp就是出错.

注:我的xml配置文件中的编码是 <?xml   version= "1.0 "   encoding= "UTF-8 "?>
是UTF-8,不是utf-8 &nbs
