You can use this code for Achiving Sending of mail,
import java.io.*;
import java.util.*;
import sun.net.smtp.SmtpClient;
public class SMTP extends Thread{
     public String whoto;
     public String username;
     public String whofrom;
/* our constructor */
public SMTP(String whoto, String username, String whofrom){
          this.whoto = whoto;
          this.username = username;
          this.whofrom = whofrom;
/* run method for multithreading */
     public void run(){
          doGet();
     public void doGet( )
     try {
          SmtpClient smtp =
                           new SmtpClient("yourdomain.com");
          smtp.from(whofrom);
          //Pass the email address of the recipient of the
          // message to the next method.
          smtp.to(whoto);
       //Get an output stream for the message
          PrintStream msg = smtp.startMessage();
          //Write the message header in the output stream.
          msg.println("To: "+whoto);
          msg.println("Subject: New Email");
          msg.println();
          //Write the text of the message in the output
          // stream
          msg.println("An event has happened.");
          msg.println("Please do not reply to this automated email.");
       //Close the stream and send the message
          smtp.closeServer();
     }catch( Exception e ) {
       e.printStackTrace();
This method is called by:
IUser loggedOnUser = (IUser) request.getUser().getUser()
SMTP mysmtp = new SMTP(whoto, loggedOnUser.getName(), whofrom);
mysmtp.start(); // starts the thread
Cheers!!
