Conversion from com.fsck.k9.mail.internet.MimeMessage to javax.mail.internet.MimeMessage

[hauke...@gmail.com]

Hi,

is there any way to convert the mail content, including attachments, from the com.fsck.k9.mail.internet.MimeMessage class to the javax.mail.internet.MimeMessage class? They seem to be similar. I tried it with piped streams, but without success. Here is what I did:

com.fsck.k9.mail.internet.MimeMessage message;
PipedInputStream in = new PipedInputStream(1024);
PipedOutputStream out = new PipedOutputStream(in);
javax.mail.internet.MimeMessage mm = new javax.mail.internet.MimeMessage(session, in);
message.getBody().writeTo(out);

Has anyone any clues what is wrong about this code, or is there a better solution for my problem?

Regards

I solved the problem the following way:

com.fsck.k9.mail.internet.MimeMessage message;

javax.mail.internet.MimeMessage mm = null;
Properties prop = System.getProperties();
Session sess = Session.getDefaultInstance(prop, null);
try {
    ByteArrayOutputStream out = new ByteArrayOutputStream();
    message.writeTo(out);
    byte[] ba = out.toByteArray();
    ByteArrayInputStream in = new ByteArrayInputStream(ba);
    mm = new javax.mail.internet.MimeMessage(sess, in);
    out.close();
    in.close();
} catch (IOException ex) {
    ex.printStackTrace();
} catch (MessagingException e) {
    e.printStackTrace();
} catch (javax.mail.MessagingException e) {
    e.printStackTrace();
}

Regards
