Sending an e-mail using java

Question

Hi,
I am sending an e-mail using java. It works fine, but I wanted to know if there is any possibility to attach a document, without using a File object. Because I have to write the File object and then delete it at the end. I would like to know if I can use for example a byte [], or something else.
Thank you very much.
This is my code, if that helps.
public static void sendWithAttach(String p_sender, String p_receiver, String p_subject,
String p_comment, int p_nombrePiecesJoints, HashMap<String, byte[]> p_files) {
Properties props = System.getProperties();
props.put("mail.smtp.host", Solapcore.getCurrent().getServletConfig().getServletContext().getInitParameter("SMTP"));
Session session = Session.getDefaultInstance(props, null);
MimeMessage sender = new MimeMessage(session);
MimeBodyPart mbp1 = new MimeBodyPart();
Multipart mp = new MimeMultipart();
List<File> listeFiles = new ArrayList<File>();
try {
//On assigne to, from, subject, body, priority
sender.setRecipients(javax.mail.Message.RecipientType.TO,
InternetAddress.parse(p_receiver, false));
sender.setFrom(new InternetAddress(p_sender));
sender.setSubject(p_subject);
mbp1.setText(p_comment);
//sender.setPriority(0);
mp.addBodyPart(mbp1);
//On attache les documents
for(Map.Entry<String, byte[]> entry : p_files.entrySet()) {
MimeBodyPart mbp2 = new MimeBodyPart();
String fileName = entry.getKey();
byte [] dataFile = entry.getValue();
File file = new File(fileName);
FileOutputStream fos = new FileOutputStream(file);
fos.write(dataFile);
mbp2.attachFile(file);
mbp2.setFileName(fileName);
mp.addBodyPart(mbp2);
listeFiles.add(file);
sender.setContent(mp);
Transport.send(sender);
}catch(MessagingException mex) {
mex.printStackTrace();
}catch(FileNotFoundException fnf) {
fnf.printStackTrace();
}catch(IOException ioe) {
ioe.printStackTrace();
}finally {
Iterator<File> itListeFiles = listeFiles.iterator();
while(itListeFiles.hasNext()) {
File tempFile = (File)itListeFiles.next();
tempFile.delete();
}
