File in multipart format. Filename in octet stream.
MultipartEntityBuilder builder = MultipartEntityBuilder.create();
builder.addTextBody("userMimeType", "application/zip", ContentType.TEXT_PLAIN);

builder.addBinaryBody("file", new FileInputStream(f), ContentType.create("application/zip"), f.getName());

Could anyone please help in finding the solution.
