Make sure mail.jar is in your classpath. Please post a code snippet that shows how you set up the mail session and send the message. Here's a snippet that works for me. I've doctored it up to indicate where your vars would be inserted:

            Properties props = System.getProperties();
            props.put ("mail.smtp.host", "your.smtp.host");
            Session mailSession = Session.getDefaultInstance (props, null);

            Message msg = new MimeMessage (mailSession);

            InternetAddress[] from = {
                new InternetAddress ("email address of sender", "personal name of sender") };
            msg.setFrom (from[0]);

            msg.addRecipient (Message.RecipientType.TO,
                new InternetAddress ("Recipient's email address", "Recipient's name"));

            msg.setSubject ("the subject");

            msg.setText ("the body of the message");
            
            // You could also use msg.setContent(..., ...);

            msg.setSentDate (new java.util.Date());

            Transport.send (msg);

Use service pack 6 - it now includes mail-related properties files in it's META-INF/
