TO SEND A EMAIL USING FILE IN JSP

JSP
SimpleSender objSendMail = new SimpleSender();
try
    {
      bSent = objSendMail.send(smtpServer, to, from, subject, body, localfile, attachName);
    }
    catch (Exception ex)
    {
      System.out.println("Usage: SimpleSender smtpServer toAddress fromAddress subjectText bodyText");  }
/**

* A simple email sender class.
*/
public class SimpleSender
{

/**
* "send" method to send the message.
*/
public boolean send(String smtpServer, String to, String from, String subject, String body, String localfile, String attachName)
{
boolean bSent = false;
try
{
Properties props = System.getProperties();

// -- Attaching to default Session, or we could start a new one --
props.put("mail.smtp.host", smtpServer);
Session session = Session.getDefaultInstance(props, null);

// -- Create a new message --
Message msg = new MimeMessage(session);

// -- Set the FROM and TO fields --
msg.setFrom(new InternetAddress(from));
msg.setRecipients(Message.RecipientType.TO,InternetAddress.parse(to,
false));

// -- We could include CC recipients too --
// if (cc != null)

// msg.setRecipients(Message.RecipientType.CC,InternetAddress.parse(cc,
false));

// -- Set the subject and body text --
msg.setSubject(subject);

// Uncomment if body text to be sent
//msg.setText(body);

// Create the message part
BodyPart messageBodyPart = new MimeBodyPart();

// Fill the message
messageBodyPart.setText(body);
Multipart multipart = new MimeMultipart();
multipart.addBodyPart(messageBodyPart);

// Part two is attachment
messageBodyPart = new MimeBodyPart();
DataSource source = new FileDataSource(localfile);
messageBodyPart.setDataHandler(new DataHandler(source));
messageBodyPart.setFileName(attachName);
multipart.addBodyPart(messageBodyPart);
msg.setContent(multipart);

// -- Set some other header information --
msg.setHeader("X-Mailer", "LOTONtechEmail");
msg.setSentDate(new Date());

// -- Send the message --
Transport.send(msg);
bSent = true;

//System.out.println("Message sent OK.");
}
catch (Exception ex)

To check if a file exist :

try{

RandomAccessFile acfp = new RandomAccessFile("xyz.txt", "r");

//display the image

}
catch(filenotfoundexception f){
//display the constant image
}
