[求助]怎么输出这个啊 - 编程论坛

我用这个文件
<%@ page contentType="text/html; charset=gb2312" language="java" import="java.sql.*" errorPage="" %>
<%@import="java.util.*;"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312" />
<title>无标题文档</title>
</head>

<body>
<form id="form1" name="form1" method="post" action="file:///C|/Program Files/Apache Software Foundation/Tomcat 5.0/webapps/myjsp/d.jsp">
请输入你的姓名
<label>
<input name="usename" type="text" id="usename" />
</label>
<label>
<input type="submit" name="Submit" value="提交" />
</label>
</form>
<%!
public String zi(String str){
String s=str;
try{
byte [] t=s.getBytes("ISO-8859-1");
s=new String (t);
return s;
}catch(Exception e){
return s;
}
}
%>
<%

out.println("你输入的是："+zi(request.getParameter("usename")));
%>
<% Date dd=new Date();
out.println(dd.toString());
%>

</body>
</html>
结果输出这个：

type Exception report

message
