Uploading multiple files in JSP

Expert:sam
Hi,

I have this code in JSP for Uploading multiple files :

<html>
<%@ page language="java" import="javazoom.upload.*,java.util.*,java.sql.*" %>

<jsp:useBean id="upBean" scope="page" class="javazoom.upload.UploadBean" >
<jsp:setProperty name="upBean" property="folderstore" value="F:/Program Files/CA/Unicenter Service Delivery/view/webapps/upload/Attach_doc"/>
</jsp:useBean>

<head>
<title>Samples : Simple Upload</title>
<style TYPE="text/css">

</style>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
</head>
<body onload="parent.resizeTo('300','500'); moveTo(0,0);" background = 'background.JPG'>
<ul class="style1">

<%
String i1=request.getParameter("req");
out.println(i1);
int i2=Integer.parseInt(request.getParameter("role"));
%>
<%

if (MultipartFormDataRequest.isMultipartFormData(request))
{
// Uses MultipartFormDataRequest to parse the HTTP request.
MultipartFormDataRequest mrequest = new MultipartFormDataRequest(request);
String todo = null;
String userid="";
if (mrequest != null) { todo = mrequest.getParameter("todo"); userid = mrequest.getParameter("Userid");}
if ( (todo != null) && (todo.equalsIgnoreCase("upload")) )
{ try{

String filename="";
Hashtable files = mrequest.getFiles();
if ( (files != null) && (!files.isEmpty()) )
{
UploadFile file = (UploadFile) files.get("uploadfile");
file.setFileName(file.getFileName());
filename=file.getFileName();
if (file != null) out.println("<li>Form field : uploadfile"+"<BR> Uploaded file : "+file.getFileName()+" ("+file.getFileSize()+" bytes)"+"<BR> Content Type : "+file.getContentType());
// Uses the bean now to store specified by jsp:setProperty at the top.
upBean.store(mrequest, "uploadfile");
//out.println(bean.insert());
}
else
{
out.println("<li>No uploaded files");
}

Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver");
//out.println("InitiLIZE");
String url="jdbc:microsoft:sqlserver://e-dhq-sladbdv:1433;databaseName=mdb";
//out.println("Conected");
Connection con1 = DriverManager.getConnection(url,"usmuser","usmuser");
//out.println("con obj");
Statement stmt=con1.createStatement();
String s1="insert into zusm_Attachment (userID,role_id,document) values ('"+request.getParameter("req")+"',"+request.getParameter("role")+",'"+filename+"')";

//out.println(s1);

stmt.executeUpdate(s1);
}catch(Exception e){
out.println(e);
}
}
else out.println("<BR> todo="+todo);
}
%>
</ul>

<form method="post" action="SimpleUpload1.jsp?req=<%=i1%>&role=<%=i2%>" name="upform" enctype="multipart/form-data">
<br><br><center><font size=5><b>Upload Attachment</b></font></center><br>
<table width="95%" border="0" cellspacing="1" cellpadding="1" align="center" class="style1">
<tr>
<td align="left">
<br><br>
<b>User ID:</b>
</td>
<td>
<INPUT TYPE="text" NAME="userID" size="30" value=<%=i1%> readonly>
</td>
<INPUT TYPE="hidden" name="role" value=<%=i2%>>
</tr>
<tr>
<td align="left">
<b>Select a file to upload :</b>
</td>

</tr>
<tr>
<td align="center">
<input type="hidden" name="todo" value="upload">
</td>
<td>
<input type="file" name="uploadfile" id="uploadfile" onchange="document.getElementById('moreUploadsLink').style.display = 'block';" />
<div id="moreUploads"></div>
<div id="moreUploadsLink" style="display:none;"><a href="javascript:addFileInput();">Attach another File</a></div>

<script>
var upload_number = 2;
var test="null";
function addFileInput() {
var d = document.createElement("div");
var file = document.createElement("input");
file.setAttribute("type", "file");
file.setAttribute("name", "uploadfile"+upload_number);
d.appendChild(file);
document.getElementById("moreUploads").appendChild(d);
upload_number++;
var test = upload_number;

}
</script>
<Center><input type="submit" name="Submit"value="Upload">
    
<input type="submit" value="Close" onclick="window.close()"></Center>
</td>
</tr>
</table>
<br>
<br>
<table border="0" cellspacing="1" cellpadding="0" align="center">
<tr>
<td bgcolor="#666666">

</td>
</tr>
</table>
</form>
</body>
</html>

Now when ever I am clicking on the upload button only the first file is getting uploaded. Please tell me what modification I need to do in the code to upload all the files attached.
