Original, off-topic answer

http://www.codejava.net/java-se/networking/upload-files-by-sending-multipart-request-programmatically Here is a good article with code that sends multipart. This worked for me.

MultipartUtility multipart = new MultipartUtility(requestURL, charset);

multipart.addHeaderField("User-Agent", "CodeJava");
multipart.addHeaderField("Test-Header", "Header-Value");

multipart.addFormField("description", "Cool Pictures");
multipart.addFormField("keywords", "Java,upload,Spring");

multipart.addFilePart("fileUpload", uploadFile1);
multipart.addFilePart("fileUpload", uploadFile2);

List<String> response = multipart.finish();

System.out.println("SERVER REPLIED:");

for (String line : response) {
    System.out.println(line);
}
