i need to backup the emails contained in a PST file (outlook storage). i'm using libpst which is the only free library i found on the web ( http://code.google.com/p/java-libpst/ )
so i can access all the information in each single email (subject, body, sender ecc..), but i need to put them on a file
here someone said you can create an EML file from a "javax.mail.Message" object: Create a .eml (email) file in Java
the problem is: how do i create this Message object? i don't have a server or an email session, just the information contained in the email
p.s. creating a .msg file would be fine too
Here's the code to create a valid eml file with java mail api. works fine with thunderbird and probably other email clients:
public static void createMessage(String to, String from, String subject, String body, List<File> attachments) {
try {
Message message = new MimeMessage(Session.getInstance(System.getProperties()));
message.setFrom(new InternetAddress(from));
message.setRecipients(Message.RecipientType.TO, InternetAddress.parse(to));
message.setSubject(subject);
// create the message part
MimeBodyPart content = new MimeBodyPart();
// fill message
content.setText(body);
Multipart multipart = new MimeMultipart();
multipart.addBodyPart(content);
// add attachments
for(File file : attachments) {
MimeBodyPart attachment = new MimeBodyPart();
DataSource source = new FileDataSource(file);
attachment.setDataHandler(new DataHandler(source));
attachment.setFileName(file.getName());
multipart.addBodyPart(attachment);
}
// integration
message.setContent(multipart);
// store file
message.writeTo(new FileOutputStream(new File("c:/mail.eml")));
} catch (MessagingException ex) {
Logger.getLogger(Mailkit.class.getName()).log(Level.SEVERE, null, ex);
} catch (IOException ex) {
Logger.getLogger(Mailkit.class.getName()).log(Level.SEVERE, null, ex);
}
}
