Hi,
It seems we are doing the homework for you; to make you start with something; look at the sample code below and try to understand it first then put the right values
to send an email with an attachement.
import java.awt.BorderLayout;
import java.awt.event.ActionEvent;
import java.util.Date;
import java.util.Properties;
import javax.activation.DataHandler;
import javax.activation.FileDataSource;
import javax.mail.Message;
import javax.mail.MessagingException;
import javax.mail.Multipart;
import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeBodyPart;
import javax.mail.internet.MimeMessage;
import javax.mail.internet.MimeMultipart;
import javax.swing.AbstractAction;
import javax.swing.Action;
import javax.swing.JButton;
import javax.swing.JComponent;
import javax.swing.JFrame;
import javax.swing.JTextField;
public class Main {
      * @param args
     public static void main(String[] args) {
          // Create the frame
          String title = "Frame Title";
          JFrame frame = new JFrame(title);
          // Create a component to add to the frame
          JComponent comp = new JTextField();
          Action action = new AbstractAction("Button Label") {
               // This method is called when the button is pressed
               public void actionPerformed(ActionEvent evt) {
                    System.out.println("sending email with attachment");
                    sendEmail();
          // Create the button
          JButton button = new JButton(action);
          // Add the component to the frame's content pane;
          // by default, the content pane has a border layout
          frame.getContentPane().add(comp, BorderLayout.SOUTH);
          frame.getContentPane().add(button, BorderLayout.NORTH);
          // Show the frame
          int width = 300;
          int height = 300;
          frame.setSize(width, height);
          frame.setVisible(true);
     protected static void sendEmail() {
          String from = "me@localhost";
          String to = "me@localhost";
          String subject = "Important Message";
          String bodyText = "This is a important message with attachment";
          String filename = "c:\\tmp\\message.pdf";
          Properties properties = new Properties();
          properties.put("mail.stmp.host", "localhost");
          properties.put("mail.smtp.port", "25");
          Session session = Session.getDefaultInstance(properties, null);
          try {
               MimeMessage message = new MimeMessage(session);
               message.setFrom(new InternetAddress(from));
               message.setRecipient(Message.RecipientType.TO, new InternetAddress(
                         to));
               message.setSubject(subject);
               message.setSentDate(new Date());
               // Set the email message text.
               MimeBodyPart messagePart = new MimeBodyPart();
               messagePart.setText(bodyText);
               // Set the email attachment file
               MimeBodyPart attachmentPart = new MimeBodyPart();
               FileDataSource fileDataSource = new FileDataSource(filename) {
                    @Override
                    public String getContentType() {
                         return "application/octet-stream";
               attachmentPart.setDataHandler(new DataHandler(fileDataSource));
               attachmentPart.setFileName(filename);
               Multipart multipart = new MimeMultipart();
               multipart.addBodyPart(messagePart);
               multipart.addBodyPart(attachmentPart);
               message.setContent(multipart);
               Transport.send(message);
          } catch (MessagingException e) {
               e.printStackTrace();
}The sample above is not ideal so you need to go through it and start to ask me some questions if you have
Let me know if you miss something
