public class SendEmail
     public static void main(String[] args)
System.out.println(args.length);
          if (args.length != 6)
               System.out.println("usage: sendmessage <to> <from> <smtphost> <true|false> <subject> <text>");
               System.exit(1);System.out.println("jj"+args.length);
     SendEmail m=new SendEmail();
     m.SendMessage(args[0],args[1], args[2], args[3], args[4], args[5]);
public static String SendMessage(String emailto, String emailfrom, String smtphost, String emailmultipart, String msgSubject, String msgText)
boolean debug = false; // change to get more information
String msgText2 = "multipart message";
boolean sendmultipart = Boolean.valueOf(emailmultipart).booleanValue();
// set the host
Properties props = new Properties();

     props.put("mail.smtp.starttls.enable","true");

props.put("mail.smtp.sendpartial", "true");
Authenticator loAuthenticator = new SMTPAuthenticator();
System.out.println("f");
// create some properties and get the default Session
Session session = Session.getDefaultInstance(props, loAuthenticator );
session.setDebug(debug);
try
// create a message
Message msg = new MimeMessage(session);
// set the from
InternetAddress from = new InternetAddress(emailfrom);
msg.setFrom(from);
InternetAddress[] address =
new InternetAddress(emailto)
//InternetAddress ad=new InternetAddress(session);
msg.setRecipients(Message.RecipientType.TO, address);
System.out.println("fc");
msg.setSubject(msgSubject);
System.out.println("fvf");
if(!sendmultipart)
// send a plain text message
msg.setContent(msgText, "text/plain");
System.out.println("fif");
else
System.out.println("felsd");
// send a multipart message// create and fill the first message part
MimeBodyPart mbp1 = new MimeBodyPart();
mbp1.setContent(msgText, "text/plain");
// create and fill the second message part
MimeBodyPart mbp2 = new MimeBodyPart();
mbp2.setContent(msgText2, "text/plain");
// create the Multipart and its parts to it
Multipart mp = new MimeMultipart();
mp.addBodyPart(mbp1);
mp.addBodyPart(mbp2);
// add the Multipart to the message
msg.setContent(mp);
Transport transport = session.getTransport("smtp");
     transport.connect(smtphost,"[email protected]","xyz");
msg.saveChanges();
System.out.println("fconn");
          //transport.sendMessage(msg,msg.getAllRecipients());
transport.sendMessage(msg,msg.getAllRecipients());
transport.close();     
//Transport.send(msg);
catch(MessagingException mex)
mex.printStackTrace();
return "Email sent to " + emailto;
class SMTPAuthenticator extends Authenticator
public PasswordAuthentication getPasswordAuthentication()
String username = "[email protected]";
String password = "xyz";
return new PasswordAuthentication(username, password);
i dont understand what the problem is..inspite of having the right code..
