How to make file attchment in java?

Question

hi
Here is the code i am using for mail attachment without attachment it is working fine
package com.nihon.login;
import java.util.Properties;
import java.util.ResourceBundle;
import javax.activation.DataHandler;
import javax.activation.DataSource;
import javax.activation.FileDataSource;
import javax.mail.BodyPart;
import javax.mail.Message;
import javax.mail.Multipart;
import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeBodyPart;
import javax.mail.internet.MimeMessage;
import javax.mail.internet.MimeMultipart;
import javax.mail.util.ByteArrayDataSource;
public class Mail {
* @param args
private static String host = null;
private static String from = null;
private static String to = null;
private static String subject = null;
private static String content = null;
private static String filename = "D:\\Users
entry.pdf";
public static void send(String fromAddress,String toAddress,String subject, String mailContent) throws Exception{
send(fromAddress,toAddress,null,subject,mailContent);
public static void send(String fromAddress,String toAddress, String ccAddress,String subject, String mailContent) throws Exception {
ResourceBundle rb = ResourceBundle.getBundle("com.nihon.login.Application");
MailInfo mail = new MailInfo();
mail.setMailServer(rb.getString("nihon.mail.server"));
if(fromAddress!=null){
mail.setFromAddress(fromAddress);
}else{
mail.setFromAddress(rb.getString("nihon.mail.fromID"));
host = mail.getMailServer();
// Get system properties
Properties props = System.getProperties();
// Setup mail server
props.put("mail.smtp.host", host);
// Get session
Session session = Session.getDefaultInstance(props, null);
// Define message
MimeMessage message = new MimeMessage(session);
// Set the from address
message.setFrom(new InternetAddress(mail.getFromAddress()));
// Set the to address
if(toAddress!=null)
message.addRecipient(Message.RecipientType.TO, new InternetAddress(toAddress));
if(ccAddress!=null){
message.addRecipient(Message.RecipientType.CC, new InternetAddress(ccAddress));
// Set the subject
message.setSubject(subject);
// Set the content
message.setText(mailContent);
For attachment
BodyPart messageBodyPart = new MimeBodyPart();
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);
// Send message
Transport.send(message);
// Method to instantiate once
public static Mail getInstance() {
if (instance == null) {
instance = new Mail();
return new Mail();
// Construtctor
protected Mail() {
private static Mail instance = null;
But now i add some code for attachment after that i got the exception in below
javax.mail.MessagingException: IOException while sending message;
nested exception is:
java.io.IOException: No content
