Interactive Session Ended
My source code is :
public class DemoSend implements ActionListener{
public void actionPerformed(ActionEvent evt) {
try {
final Properties props = System.getProperties();
props.put("mail.host", hostField.getText());
final Session mailConnection = Session.getDefaultInstance(props, null);
final MimeMessage msg = new MimeMessage(mailConnection);
final Address to = new InternetAddress(toField.getText());
final Address from = new InternetAddress(fromField.getText());
msg.setContent(message.getText(), "text/plain");
msg.setFrom(from);
msg.setRecipient(Message.RecipientType.TO, to);
msg.setSubject(subjectField.getText());
msg.setSentDate(new java.util.Date());
final MimeBodyPart mbp1 = new MimeBodyPart();
mbp1.setText(message.getText());
final MimeBodyPart mbp2 = new MimeBodyPart();
mbp2.setDisposition(mbp2.ATTACHMENT);
final FileDataSource fds=new FileDataSource(FileName);
mbp2.setDataHandler(new DataHandler(fds));
mbp2.setFileName(fds.getName());
final Multipart mp = new MimeMultipart();
mp.addBodyPart(mbp1);
mp.addBodyPart(mbp2);
msg.setSentDate(new Date());
msg.setContent(mp);
Runnable r = new Runnable() {
public void run() {
try {
Transport.send(msg);
JOptionPane.showMessageDialog(null," Your message has been sent successfuly","G T P Email Client",JOptionPane.INFORMATION_MESSAGE);
catch (Exception e) {
e.printStackTrace();
JOptionPane.showMessageDialog(null," -- E r r o r -- Your message has not been sent!!!!! ","G T P Email Client",JOptionPane.INFORMATION_MESSAGE);
Thread t = new Thread(r);
t.start();
message.setText("");
catch (Exception e) {
e.printStackTrace();
and i define at the beggining the string FileName
public static String FileName = new String();
and thats for the attach button
attachButton.addActionListener(new ActionListener()
public void actionPerformed(ActionEvent e)
if (fc == null) {
fc = new JFileChooser();
fc.addChoosableFileFilter(new ImageFilter());
fc.setAcceptAllFileFilterUsed(true);
fc.setFileView(new ImageFileView());
fc.setAccessory(new ImagePreview(fc));
fc.setMultiSelectionEnabled(true);
int returnVal = fc.showDialog(Send.this,"Attach File");
fc.getSelectedFile();
File file = fc.getSelectedFile();
It would be a great help if you can can help me find an answer to my problem.
Thanks in advance.

Answer 1

I tried to set a specific file for the FileChooser but again the same results.I tried without the preview classes again the same mistake.But when i tried without the JFileChooser it worked, but i must use a JFileChooser in order to choose a file to attach.I used a simple FileChooser and again the same mistakes.I don't know where the mistake is.
I will be grateful if you can help me out,this is an emergency it is for my project and i'm desperate.
I include the whole class.
Thanks again and sorry for the long message.
I hope you have some free time to help me out.
Thanks again
