public class SendMailUsage {
public static void main(String[] args) {
// SUBSTITUTE YOUR EMAIL ADDRESSES HERE!!!
String to = "[email protected]";
String from = "[email protected]";
// SUBSTITUTE YOUR ISP'S MAIL SERVER HERE!!!
String host = "172.13.2.48";
// Create properties for the Session
Properties props = new Properties();
// If using static Transport.send(),
// need to specify the mail server here
props.put("mail.smtp.host", host);
// To see what is going on behind the scene
props.put("mail.debug", "false");
// Get a session
Session session = Session.getInstance(props);
try {
// Get a Transport object to send e-mail
Transport bus = session.getTransport("smtp");
bus.connect();
Message msg = new MimeMessage(session);
msg.setFrom(new InternetAddress(from));
InternetAddress[] address = {new InternetAddress(to)};
msg.setRecipients(Message.RecipientType.TO, address);

msg.setSentDate(new Date());
// Set message content and send
setTextContent(msg);
msg.saveChanges();
bus.sendMessage(msg, address);
bus.close();
catch (MessagingException mex) {
// Prints all nested (chained) exceptions as well
mex.printStackTrace();
// How to access nested exceptions
while (mex.getNextException() != null) {
// Get next exception in chain
Exception ex = mex.getNextException();
ex.printStackTrace();
if (!(ex instanceof MessagingException)) break;
else mex = (MessagingException)ex;
// A simple, single-part text/plain e-mail.
public static void setTextContent(Message msg) throws MessagingException {
// Set message content
String mytxt = "this mail is generated by java";
msg.setText(mytxt);
// Alternate form
msg.setContent(mytxt, "text/plain");
} //End of class

Turn on session debugging to get the protocol trace. Your mail server
is probably saying more about why the send failed than what you've
included here.
Then read the FAQ for likely problems.
