Hi I've the following code for sending java mail with attachment. Its sending the mail but not attaching the file. Please could someone help. Thanks
/* Bean Properties */

private String to = "mail@xxx.com";
private String from = null;
private String subject = null;
private String message = null;
private File attach =null;
public static Properties props = null;
public static Session session = null;

static {
/*Setting Properties for STMP host */
props = System.getProperties();
props.put("mail.smtp.host", "mail.xxx.com");
session = Session.getDefaultInstance(props, null);
}
/* Setter Methods */
public void setTo(String to) {
this.to = to;
}

public void setFrom(String from) {
this.from = from;
}

public void setSubject(String subject) {
this.subject = subject;
}

public void setMessage(String message) {
this.message = message;
}

public void setAttach(File attach) {
this.attach = attach;
}
/* Sends Email */
public void sendMail() throws Exception {
if(!this.everythingIsSet())
throw new Exception("Could not send email.");
try {
MimeMessage message = new MimeMessage(session);
message.setRecipient(Message.RecipientType.TO,
new InternetAddress(this.to));

message.setFrom(new InternetAddress(this.from));
message.setSubject(this.subject);
message.setText(this.message);
// create and fill the first message part
MimeBodyPart mbp1 = new MimeBodyPart();
mbp1.setText(this.message);

// create the second message part
MimeBodyPart mbp2 = new MimeBodyPart();

// attach the file to the message
javax.activation.DataSource fds = new FileDataSource(attach);
mbp2.setDataHandler(new DataHandler(fds));
mbp2.setFileName(fds.getName());

// create the Multipart and its parts to it
Multipart mp = new MimeMultipart();
mp.addBodyPart(mbp1);
mp.addBodyPart(mbp2);

// add the Multipart to the message
message.setContent(mp);
message.setText(this.message);
Transport.send(message);



}
catch (MessagingException e) {
throw new Exception(e.getMessage());
}
}

You can't use both
message.setContent(mp);
message.setText(this.message);
in the same piece of code!
Use message.setText(...) for emails without attachments and message.setContent(...) for emails with attachments.

Hiya, I got the following error message after taking the setText() out.
Sending failed; nested exception is: javax.mail.MessagingException: IOException while sending message; nested exception is: java.io.FileNotFoundException: C:\j3t\attach.txt (No such file or directory)

The error message is telling you the program is not able to find the file "C:\j3t\attach.txt".

if C:\j3t\attach.txt does exist, then try
C:\\j3t\\attach.txt or even C:/j3t/attach.txt.
Hope that helps.

Are you sure the file exists?
I just took your code posted above, compiled and executed it, and it worked fine. Sent the attachment and everything.

The SMTP server I used was an iMail server, but that shouldn't make any difference. All I did was put your code into a class, insert a few system outs, and add a main method.

Hi Nilesh, thanks for that code, Its sort of working. I didnt use the main method, i hard coded everything in the bean property. Now the test is to take these values from the form.
Thanks xx

Hey Delanthi,
You are welcome. But for the record, the only reason I could help you was because I had already made those errors before.
