How to retrieve String on Servlet send as a part of Multipart Post

Question

This may be very simple question but I have been looking around for a while. I am sending two strings to a Java Servlet on Tomcat 7.

multipartContent.addPart("destadd", sb1);
multipartContent.addPart("destfilename", sb2);

I am trying to retrieve these String like this

String destFileName = request.getPart("destfilename").getName();

but in vein. I will appreciate any help.

I was running around for two days almost, fianlly I got the answer

Part destFileNamePart = request.getPart("destfilename");
Scanner s = new Scanner(destFileNamePart.getInputStream());
String destFileName = s.nextLine();

A little bit late but it may help for someone else:

IOUtils.toString( destFileNamePart.getInputStream() );

It works like a charm, thanks, i assume this more optimized than using the scanner ? – Jean T Jan 02 '20 at 08:27

Have you looked at Get form parameters from multipart request without getting the files.

You can also use utility class such as O'Reilly MultipartRequest and more info here

Don't use O'Reilly MultipartRequest. It's older than your grandfather. Use Apache Commons FileUpload. – BalusC Apr 29 '12 at 05:03
