This is my JSP code index.jsp

<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Sync Data</title>
</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>
<tr><td><input type="submit" value="Sync >>" /></td></tr>
</table>
</form>

</body>

</html>

---------------------------------------------------------------------------

SyncData.java


import java.io.IOException;
import java.io.PrintWriter;
import java.util.ArrayList;
import java.util.Iterator;
import java.util.List;
import java.util.StringTokenizer;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.apache.commons.fileupload.FileItem;
import org.apache.commons.fileupload.disk.DiskFileItemFactory;
import org.apache.commons.fileupload.servlet.ServletFileUpload;

public class SyncData extends HttpServlet {

@Override
public void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

response.setContentType("text/html");
PrintWriter out = response.getWriter();
List userIds = new ArrayList();
try {
if (ServletFileUpload.isMultipartContent(request)) {
ServletFileUpload servletFileUpload = new ServletFileUpload(new DiskFileItemFactory());
List fileItemsList = servletFileUpload.parseRequest(request);
Iterator iterator = fileItemsList.iterator();
while (iterator.hasNext()) {
FileItem item = (FileItem) iterator.next();




if (item.isFormField()) {

if (item.getFieldName().equals("singleUserId")) {
userIds.add(item.getString());
}
} else if (!item.isFormField()) {

StringTokenizer s = new StringTokenizer(item.getString());
while (s.hasMoreTokens()) {
String str = s.nextToken();

if (!str.equalsIgnoreCase("User") && !str.equalsIgnoreCase("ID")) {
userIds.add(str);
}
}
}
}
}
out.println(" userid >>");
} catch (Exception e) {
e.printStackTrace();
}
}
