JavaMail: MIMEMessages from E-mails on disk?

[Ed Beaty]

Hello! I have folders of archived E-mails saved to disk that I need to sort through. I would like to use JavaMail to create MIMEMessages from the saved mails, then get at the headers, recipient, contents and so on. The problem is that I don't know how to create MIMEMessages from an InputStream without having a valid Session and/or Folder, and that appears to require the URL of a valid E-mail server. Is it possible to create a Session that represents a set of locally stored E-mails, and not a live mail server, which I could then use to create my MIMEMessages? Alternately, can anyone recommend a simple way of getting at the MIME information (including attachments) in my files?

As always, any help would be very greatly appreciated.
Thank you,
Ed Beaty

I did some searching, and found a possible solution. It appears to generate a "null session" which does not require a live E-mail server to read mails from an input stream:

 
Session session = Session.getDefaultInstance(new Properties(), null);
InputStream in = new FileInputStream("c:\\test\\spam.eml");
MimeMessage message = new MimeMessage(session , in);
System.out.println(message.getSubject());  //make monkey fast!
System.out.println(message.getFrom()[0]);  //aspammer <[e-mail]>
System.out.println(message.getSentDate()); //Fri Jun 17 17:12:20 CDT 2005

Comments? Is there a better/safer/more efficient way to do this?
Thanks,
Ed
