I usually define my javamail session in the GlobalNamingResources section of tomcat's server.xml file so that my code does not depend on the configuration parameters:

and I get the session via JNDI:

    Context context = new InitialContext();
    Session sess = (Session) context.lookup("java:comp/env/mail/Mail");

    MimeMessage message = new MimeMessage(sess);
    message.setFrom(new InternetAddress(from));
    message.addRecipient(Message.RecipientType.TO, new InternetAddress(to));
    message.setSubject(subject, "UTF-8");
    message.setText(content, "UTF-8");
    Transport.send(message);
