This will depend. I've used the following technique to upload a multi-part file to a server before, based on providing a series of form key/name pairs.

This will be depended on you own requirements and what the servlet is actually expecting...

MultipartEntity entity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE);

String name = file.getName();

entity.addPart(new FormBodyPart("someFormParameter", new StringBody("someFormName")));
/*...*/
entity.addPart("formFileNameParameter", new FileBody(file, mimeType));

HttpClient client = /*...*/

HttpPost post = new HttpPost(url.toURI());
post.setEntity(entity);
HttpResponse response = client.execute(post);

// Process response
