Answer 1

Just want to add to the answer. I was trying to figure how to append text fields to the body and created the following function to do it:

private void buildTextPart(DataOutputStream dataOutputStream, String parameterName, String parameterValue) throws IOException {
    dataOutputStream.writeBytes(twoHyphens + boundary + lineEnd);
    dataOutputStream.writeBytes("Content-Disposition: form-data; name=\"" + parameterName + "\"" + lineEnd);
    dataOutputStream.writeBytes("Content-Type: text/plain; charset=UTF-8" + lineEnd);
    dataOutputStream.writeBytes(lineEnd);
    dataOutputStream.writeBytes(parameterValue + lineEnd);
}

It is working pretty well.
