URGENT -java MAil sending pdf as attachment

Question

I have a small java program that sends the pdf as an attachment without using phisical pdf file.
but the problem is i am unable to open the pdf that comes as as attachment in mail.
error while opening pdf : " acrobat cannot open file bcos the file type is not supported or the file is curropted(for example it was sent as email attachment and was not properly decoded)"
here is the code :
import java.util.Properties;
import javax.mail.*;
import javax.mail.internet.*;
import javax.activation.*;
import java.io.*;
import java.util.*;
public class Mailer {
public static void main (String args[]) {
String host = "abc";
String from ="[email protected]";
String to = "[email protected]";
//String fileAttachment = args[0];
// 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
MimeMessage message = new MimeMessage(session);
message.setFrom( new InternetAddress(from));
message.addRecipient(Message.RecipientType.TO, new InternetAddress(to));
message.setSubject("Hello JavaMail Attachment subject");
// create the message part
MimeBodyPart messageBodyPart = new MimeBodyPart();
//fill message
messageBodyPart.setText("Hi hello this is the msg in mail");
Multipart multipart = new MimeMultipart();
multipart.addBodyPart(messageBodyPart);
// Part two is attachment
messageBodyPart = new MimeBodyPart();
String data_to_send = "This msg is sent as an attachment with out using physical file";
String att_type = "application/pdf";
messageBodyPart.setText(data_to_send);
messageBodyPart.setHeader("Content-Type", att_type);
messageBodyPart.setHeader("Content-Transfer-Encoding", "BASE64");
messageBodyPart.setFileName("attachment.pdf");
/* ByteArrayOutputStream byteStream=new ByteArrayOutputStream();
ObjectOutputStream objectStream=new ObjectOutputStream(byteStream);
objectStream.writeObject(data_to_send);
messageBodyPart.setDataHandler(new DataHandler( new ByteArrayDataSource( byteStream.toByteArray(), "application/pdf" )));
     messageBodyPart.setFileName("attachment.pdf");
multipart.addBodyPart(messageBodyPart);
// Put parts in message
message.setContent(multipart);
// Send the message
Transport.send( message );
System.out.println("sent msg");
Thanks

It's "corrupted" because you are sending a text string and not a PDF document.
And that commented-out code that uses an ObjectOutputStream would have corrupted a PDF document anyway, if you had one.
I suggest if this problem is urgent then you hire professional programming help to get it done. You are a long way from a solution.
