我用过这个方法但问题依然！我的代码是
<%String s = request.getParameter("myError");
String ss = new String(s.getBytes("ISO8859-1"), "gb2312");
our.println(ss);
%>
是否有误！！！
还望告知！！！谢谢！！
jsp的第一行要加:<%@ page contentType="text/html; charset=GBK" %> String sCourseName = request.getParameter("CourseName");
sCourseName = new String(sCourseName.getBytes("ISO8859_1"),"GBK");
看看这个：
blog.csdn.net/qixiaopackage Beans;
import java.io.Serializable;
public class IsoToGb implements Serializable{
   public IsoToGb(){
   }
   public String Excute(String sIso){
      try{String str=sIso;
      byte[] temp_t=str.getBytes("ISO8859-1");
      String temp=new String(temp_t);
      return temp;
   }
      catch(Exception e){ }
      return "NULL";
   }
}<%@ page contentType="text/html;charset=gb2312"%>
<html>
<head>
<title>Login.jsp</title>
</head>
<body>
<%
   Beans.Login myLogin=new Beans.Login();
   Beans.IsoToGb myIsoToGb=new Beans.IsoToGb();
   Beans.GbToIso myGbToIso=new Beans.GbToIso();
%><%
   Beans.Login myLogin1=new Beans.Login(myGbToIso.Excute("张亮飞"),"pass");
%>
myLogin1 get id is <%= myIsoToGb.Excute(myLogin1.getId()) %><br>
<%
   myLogin.setId(request.getParameter("id"));
   myLogin.setPassword(request.getParameter("password"));
%>
submited id is <%= myIsoToGb.Excute(myLogin.getId()) %><br>
submited password is <%= myIsoToGb.Excute(myLogin.getPassword()) %>
</body>
<html>
request.setCharacterEncoding("gb2312");给你一条，一句话搞定
<%request.setCharacterEncoding("gb2312");%>
<@ page contentType="text/html; charset=GBK" %> <%request.setCharacterEncoding("gb2312");%>String sCourseName = request.getParameter("CourseName");
sCourseName = new String(sCourseName.getBytes(),"GBK");        //getBytes()不要参数
加上它们就ok；
加上 <%@ page contentType="text/html; charset=GB2312" language="java" %>
最好在获得参数前
加一句:
<%request.setCharacterEncoding("gb2312");%>
<%@ page contentType="text/html; charset=GB2312" language="Java"%>
