html提交中文表单到servlet，然后servlet输出到浏览器中变成了“？”。
这是html:
<!DOCTYPE html>
<html>
<head>
<title>hello.html</title>
<meta name="keywords" content="keyword1,keyword2,keyword3">
<meta name="description" content="this is my page">
<meta name="content-type" content="text/html; charset=gb2312">
<!--<link rel="stylesheet" type="text/css" href="./styles.css">-->
</head>
<body>
<form action="HelloForm" method="GET">
名字：<input type="text" name="first_name">
<br />
姓氏：<input type="text" name="last_name" />
<input type="submit" value="提交" />
</form>
</body>
</html>
这是servlet中的doget方法：
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
//response.setContentType("text/html;charset=GBK");
response.setContentType("text/html;charset=gb2312");
PrintWriter out = response.getWriter();
String title = "使用 GET 方法读取表单数据";
String docType =
"<!doctype html public \"-//w3c//dtd html 4.0 " +
"transitional//en\">\n";
out.println(docType +
"<html>\n" +
"<head><title>" + title + "</title></head>\n" +
"<body bgcolor=\"#f0f0f0\">\n" +
"<h1 align=\"center\">" + title + "</h1>\n" +
"<ul>\n" +
" <li><b>名字</b>："
+ request.getParameter("first_name") + "\n" +
" <li><b>姓氏</b>："
+ request.getParameter("last_name") + "\n" +
"</ul>\n" +
"</body></html>");
