Select File1 <input type="file" name="file1" />
Select File2 <input type="file" name="file2" />

import javazoom.upload.*;
import java.util.*;
public class UplSrv1 extends HttpServlet {
public void doPost(HttpServletRequest req, HttpServletResponse res)
throws ServletException, IOException {
PrintWriter pw = res.getWriter();
try {
// set location for saving uploded files
UploadBean upb = new UploadBean();
upb.setFolderstore("c:/store");
upb.setOverwrite(false);
MultipartFormDataRequest nreq = new MultipartFormDataRequest(req);
upb.store(nreq); // completes files uploding
// display names of the uploded files
pw.println("The uploded files are ");
Hashtable ht = nreq.getFiles();// gives all uploded files
Enumeration e = ht.elements();
while (e.hasMoreElements()) {
UploadFile file = (UploadFile) e.nextElement();
pw.println(file.getFileName() + " ");
}// while
}// try
catch (Exception e) {
pw.println(e);
}// catch
}// doPost ()
}// class
Jars required in classpath
servlet-api.jar
uploadbean.jar
Jars required in lib Folder
(See the directory structure)
Compile the ServletProgram
c:\JavaZoomUpload\WEB-INF\classes>javac *.java
Running the Application
