急！！！request.getParamter(textbox)时乱码！！！

Question

String s = request.getParamter("textbox");s = new String(s.getbytes("ISO8859-1"),"gb2312");

Answer 1

调用这个函数trans(××)就可以了：
String trans(String chi)
{
String result = null;
               byte temp [];
               try
               {
                       temp=chi.getBytes("ISO-8859-1");
                      result = new String(temp);
                }
                catch(java.io.UnsupportedEncodingException e)
                {
                        System.out.println (e.toString());
                }
return result;
}
String trans(Object chi)
{
   return trans(chi.toString());
  }

引入个标签<%@ taglib uri="http://java.sun.com/jstl/fmt" prefix="fmt" %>
<fmt:requestEncoding  value="gb2312"/>
