Problem to send out attachment

Question

Hi all,
This is urgent. Any advice is appreciated. I have java class to send out attachement. The program was working fine without any issues until last Friday. Suddenly, it could not send any attachment email out. I was able to send out a simple email without attachment. I did not know what changed. I ran out of resources for troubleshooting it.
Here is my code:
import java.util.Properties;
import javax.mail.*;
import javax.mail.internet.*;
import javax.activation.*;
public class SendAttachment {
public void Send (String MailHost, String AddFrom, String AddTo, String FileAttName)
throws Exception {
String host = MailHost;
String from = AddFrom;
String to = AddTo;
String fileAttachment = FileAttName;
// Get system properties
Properties props = System.getProperties();
// Setup mail server
props.put("mail.smtp.host", host);
// Get session
Session session =
Session.getInstance(props, null);
// Define message
Message message =
new MimeMessage(session);
message.setFrom(
new InternetAddress(from));
message.addRecipient(
Message.RecipientType.TO,
new InternetAddress(to));
message.setSubject(
"Hello JavaMail Attachment");
// create the message part
BodyPart messageBodyPart =
new MimeBodyPart();
//fill message
messageBodyPart.setText("Hi");
Multipart multipart = new MimeMultipart();
multipart.addBodyPart(messageBodyPart);
// Part two is attachment
messageBodyPart = new MimeBodyPart();
DataSource source =
new FileDataSource(fileAttachment);
messageBodyPart.setDataHandler(
new DataHandler(source));
messageBodyPart.setFileName(fileAttachment);
multipart.addBodyPart(messageBodyPart);
// Put parts in message
message.setContent(multipart);
// Send the message
Transport.send( message );
my test program:
import java.io.File;
import java.io.IOException;
import java.io.OutputStream;
public class TestJavaMail {
public static void main(String[] args) {
String myhost =args[0];
String from =args[1];
String to = args[2];
String filename = args[3];
try {
System.out.println("Start .....");
System.out.println("Preparing...");
SendAttachment app = new SendAttachment();
app.Send(myhost, from, to, filename);
System.out.println("Success!");
} catch (Exception e) {
//System.err.println(ExceptionUtil.printStackTrace(e));
System.exit(-1);
After successful compilation, here is how I ran the class:
java TestJavaMail mymaihost.com [email protected] [email protected] /tmp/test.txt
It stops just before it calls Transport.send( message );
Any ideas are greatly appreciated.
