乱码的问题!
我写了一个非常简单的表单提交页面test3.jsp，可是输入中文提交，显示就是乱码，我在一本书上看到一个解决方法写了一个getStr，可是还是乱码，这个问题该如何解决？
<html>
<head>
<title>test</title>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312">
</head>
<body bgcolor="#FFFFFF" text="#000000">
<center>
<%!
public String getStr(String str)
{
try
{
String temp_p=str;
byte[] temp_t=temp_p.getBytes("ISO8859-1");
String temp=new String(temp_t);
return temp;
}
catch(Exception e)
{
}
return "null";
}
%>
<%!
String username;
%>
<%
username =request.getParameter("username");
username = getStr(username);
out.println (username);
%>
<form name="form1" method="post" action="test3.jsp">
<p>姓名：
<input type="text" name="username">
</p>

<input type="submit" name="Submit" value="Submit">

直接用
username = new String(username.getBytes("ISO-8859-1"),"gb2312");
就行！
username = new String(username.getBytes("ISO-8859-1"),"gb2312");
就行！
