</head>
<body>
<h1>Sync Data</h1>
<p>Please use the following input box to upload file or enter the user id in input box directly.</p>
<form method="post" action="SyncData" enctype="multipart/form-data">
<table width="600px" cellpadding="5px" cellspacing="10px" valign="middle">
<tr><td>Upload File:</td><td><input type="file" name="userIds" size="32"></td></tr>
<tr><td>Enter UserId:</td><td><input type="text" name="singleUserId"></td></tr>

response.setContentType("text/html");
PrintWriter out = response.getWriter();
List userIds = new ArrayList();
try {

ServletFileUpload servletFileUpload = new ServletFileUpload(new DiskFileItemFactory());
List fileItemsList = servletFileUpload.parseRequest(request);
Iterator iterator = fileItemsList.iterator();
while (iterator.hasNext()) {
FileItem item = (FileItem) iterator.next();
