[rakesh_n_mehta]

hello friends,

i am making one application. in that i have to forward file to mail through attechment. i have taken one example code but its not working properlly.

code is


import java.util.*; import java.io.*; import javax.mail.*; import javax.mail.internet.*; import javax.activation.*;

public class AttachExample {

public static void main (String args[]) throws Exception {
String host = "smtp.kar.com";
String from = "FromAddre@kar.com";
String to[] = new String[]{"ABC@kar.com","XYZ@kar.com"};
String filename = "AttachFile.txt";
// Get system properties
Properties props = System.getProperties();
props.put("mail.smtp.host", host);

Session session = Session.getInstance(props, null);
System.out.println(session.getProperties());

Message message = new MimeMessage(session);
message.setFrom(new InternetAddress(from));

InternetAddress[] toAddress = new InternetAddress[to.length];
for (int i = 0; i < to.length; i++)
toAddress[i] = new InternetAddress(to[i]);
message.setRecipients(Message.RecipientType.TO, toAddress);
message.setSubject("Hello JavaMail Attachment");
BodyPart messageBodyPart = new MimeBodyPart();
messageBodyPart.setText("Here's the file");
Multipart multipart = new MimeMultipart();
multipart.addBodyPart(messageBodyPart);
messageBodyPart = new MimeBodyPart();
DataSource source = new FileDataSource(filename);
messageBodyPart.setDataHandler(new DataHandler(source));
messageBodyPart.setFileName(filename);
multipart.addBodyPart(messageBodyPart);
message.setContent(multipart);
try{
Transport.send(message);
}
catch(SendFailedException sfe)
{
message.setRecipients(Message.RecipientType.TO, sfe.getValidUnsentAddresses());
Transport.send(message);

}
}

}

Go to GMail's web site and review their documentation. Many SMTP services don't accept connections on port 25, and I think gmail may required SSL/TLS. They seem pretty good about describing their requirements, including ports.

[Eranga]

I don't know about the port, but gmail needs SSL/TLS for connections.

[rakesh_n_mehta]

hello
if anybody knows some other code for that then plz give me ...

[rakesh_n_mehta]

Hello friends,

As you told gmail needs SSL/TLS for connections. i change my coding now its not giving error of port.. but another error

so any suggestion ??




thank for reply..

[Eranga]

In simply for me, authentication fail, as the exceptions shows there. How did you authenticate it?

[Steve11235]

Glancing at your code, it appears you commented out the code where you specify the user name and password in the Properties instance. That would certainly lead to an authentication error ;-)

The real question is, what do you put in these fields?

First, gmail won't let you use their service without creating an account, which seems reasonable. Create a gmail account, and use the user name and password from that.

[Eranga]

And one more thing too, to our thread starter. Please use the code tags when you posting code segments again. Un-formated codes are hard to read lol.

[rakesh_n_mehta]

Hey friend ,

thanks to all.
also i will mention code tags from next time.

[rjuyal]

Rakesh is it working now ?

[rakesh_n_mehta]

yes rjuyal

it working fine ...
having some problem when we r sending pdf file but that is because of its size .. i will solve that problem.. main problem was wth line

props.put("mail.smtp.host","mail.gmail.com");


in that i have to write props.put("mail.smtp.host","smtp.gmail.com");

....and authentication..

Session session = Session.getDefaultInstance(props, new Authenticator(){protected PasswordAuthentication getPasswordAuthentication() {return new PasswordAuthentication(username, password); }});


now code is working...:)
