I have a MimeMultiPart object with two MimeBodyParts and I want to POST this MimeMultiPart object to an HTTPS address. One body part is an xml document and the other is a regular text file. Can somebody tell me how to do this?


My code looks something like this:




System.setProperty("java.protocol.handler.pkgs", "com.sun.net.ssl.internal.www.protocol");



java.security.Security.addProvider(new com.sun.net.ssl.internal.ssl.Provider());



URL url = new URL("https://www.sun.com");

HttpURLConnection conn = (HttpURLConnection) url.openConnection();



conn.setDoOutput(true);



conn.setRequestProperty("content-type", "multipart/mixed");



MimeMultipart mimeMultipart = new MimeMultipart();



MimeBodyPart xmlPart = new MimeBodyPart();

xmlPart.setHeader("Content-Type", "text/xml; charset=UTF-8");

xmlPart.setHeader("Content-ID", " <12345678>");



xmlPart.setContent(" <?xml version="1.0" encoding="UTF-8"?> somevalue ");

mimeMultipart.addBodyPart(xmlPart);




MimeBodyPart attachmentPart = new MimeBodyPart();

File file = new File("file.txt");

FileDataSource fds = new FileDataSource(file);

DataHandler dh = new DataHandler(fds);
attachmentPart.setFileName("file.out");


attachmentPart.setHeader("Content-Type", "text/plain; charset=US-ASCII");

attachmentPart.setHeader("Content-ID", "98765432");

attachmentPart.setDisposition(Part.ATTACHMENT);

attachmentPart.setDataHandler(dh);



mimeMultipart.addBodyPart(attachmentPart);



mimeMultipart.writeTo(conn.getOutputStream());
