<script type="text/javascript">
function reload_filepath(path)
{
	document.certForm.de_file_path.value = path;
}
</script>
</head>
<body>
<h1>上传证件</h1>
 <form action="" name="certForm" method="post">
  <table border="1" cellpadding="0" cellspacing="0">
     <tr>
	    <td>
	           保存路径：
	    </td>
	    <td>
			<input name="de_file_path" size="50" maxlength="200" readonly="true" />
	    </td>
	    <td>
	      <a href="#" onClick='JavaScript:window.open("upload.jsp?type=cert_file&agid=00393","","top=200,left=300,width=300,height=130")'>[上传证书]</a>&nbsp;
	    </td>
    </tr> 
   </table>
 </form>
</body>
</html>

2.upload.jsp页面如下：

<%@ page contentType="text/html;charset=GBK"%>
<html>
<head>
<title>文件上传</title>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312">

<body>
获取参数:<%=request.getQueryString() %>
<form action="upload_post.jsp?<%=request.getQueryString()%>" method="post" enctype="multipart/form-data" name="form1">
  <input name="file_data" type="file" id="file_data">
  <input type="submit" name="Submit" value="上传">
</form>
<center><input type=button value="关闭" onclick="javascript:window.close()"></center>

3.upload_post.jsp页面如下：

<%@page import="com.hsp.base.Constants"%>
<%@page import="com.hsp.util.LoggerUtils"%>
<jsp:useBean id="mySmartUpload" scope="page" class="com.jspsmart.upload.SmartUpload" /><!--jsp:useBean标签用于在JSP页面创建bean实例，相当于new-->
