Extract nested .msg attachment using javamail api

Question

I've outlook email data in the firm of EML files. There are various levels of nesting of attachments.

Is there a generic way to extract the attached .msg and its attachments recursively?

A full piece of code or relevant code snippet would be much more helpful than plain approach.

The JavaMail sample program msgshow.java should help.

So is it an EML file or an MSG file?

You might consider using a library called msgparser.

They list some very basic usage examples:

MsgParser msgp = new MsgParser();
Message msg = msgp.parseMsg("mail.msg");

String fromEmail = msg.getFromEmail();
String fromName = msg.getFromName();
String subject = msg.getSubject();

List<Attachment> atts = msg.getAttachments();
for (Attachment att : atts) {
  // do something with attachment
}

the function List<Attachment> atts = msg.getAttachments(); for (Attachment att : atts) { // do something with attachment } is returning file name like abc.pdf, now how can I get this abc.pdf or how can I open it, its returning only attachment name
