I want to offer to upload multiple files clicking upload button only once. Can I use multipart to send files? If yes, then how?
P.S.: I don't want to use flash or send one file at a time.

In you HTML, you can do the following :
<input accept="image/jpeg,image/gif,image/png" type="file" name="upload[]" multiple/>
adding multiple to the end of your input grants you what you want.

Hope This Helps...
//JSP File
<html>
<head><title>Upload page</title></head></p> <p><body>
<form action="upload_file" method="post" enctype="multipart/form-data" name="form1" id="form1">
<center>
Specify file: <input name="file" type="file" id="file">
Specify file: <input name="file" type="file" id="file">
Specify file:<input name="file" type="file" id="file">
<input type="submit" name="Submit" value="Submit files"/>
<center>
</form>
</body>
</html>
//Servlet Page
import java.util.List;
import java.util.Iterator;
import org.apache.commons.fileupload.servlet.ServletFileUpload;
import org.apache.commons.fileupload.disk.DiskFileItemFactory;
import org.apache.commons.fileupload.*;
boolean isMultipart = ServletFileUpload.isMultipartContent(request);
if (!isMultipart) {
}
else{
FileItemFactory factory = new DiskFileItemFactory();
ServletFileUpload upload = new ServletFileUpload(factory);
List items = null;
try {
items = upload.parseRequest(request);
} catch (FileUploadException e) {
e.printStackTrace();
}
Iterator itr = items.iterator();
while (itr.hasNext()) {
FileItem item = (FileItem) itr.next();
if (item.isFormField()) {
} else {
try {
String itemName = item.getName();
File savedFile = new File(config.getServletContext().getRealPath("/")+"uploadedFiles/"+itemName);
item.write(savedFile);
out.println("<tr><td><b>Your file has been saved at the loaction:</b></td></tr><tr><td><b>"+config.getServletContext().getRealPath("/")+"uploadedFiles"+"\\"+itemName+"</td></tr>");
} catch (Exception e) {
e.printStackTrace();
}
}
}

No, I cannot use apache commons(or any external library), Also I have to monitor progress of ho much file has been uploaded. that I have to handle in JS :)
Yes, you can. Try apache fileupload library, you may refer to this question on stackoverflow: Multiple file upload in Jsp using Apache commons file upload API or this full example. Also you may take use of Spring by referencing this article.
