PDF File corrupted when being sent by email by tomcat... what's wrong?

Question

Hi,
I have been a little frustrated trying tomcat to send a pdf file by email after it have been uploaded to the server.
First case:
If i run the same code in windows, it works.
Second case:
If i run the same code manually in java in the tomcat linux server it works.
Third case:
The problem is when the code is running by tomcat in a jsp page.
In every situation the email goes to the sender, but in the last one, the reported size of the pdf file is not the same as the first and second case resulting in a pdf corruption. It cannot be opened.
I am running Tomcat 5.5.17 with jdk 1.5.0.10 in a Redhat Enterprise Linux 4 Server.
This is the code called by a jsp page.
package eor;
import java.util.Date;
import java.util.Properties;
import javax.activation.DataHandler;
import javax.activation.FileDataSource;
import javax.mail.Authenticator;
import javax.mail.Message;

public class SendMailUsingAuthentication {
private static final String SMTP_AUTH_USER = "user";
private static final String SMTP_AUTH_PWD = "pass";
public void sendEmail() {
String from = "[email protected]";
String to = "[email protected]";
String subject = "Sendit from linux ";
String bodyText = "This is a important message with attachment";
String filename = "//home//test//HON-SOLMANT28AGO08.pdf";
Properties properties = new Properties();
properties.put("mail.smtp.host", "Testmailhost");
properties.put("mail.smtp.auth", "true");
properties.put("mail.smtp.port", "25");
Authenticator auth = new SMTPAuthenticator();
Session session = Session.getInstance(properties, auth);
session.setDebug(true);
try {
MimeMessage message = new MimeMessage(session);
message.setFrom(new InternetAddress(from));
message.setRecipient(Message.RecipientType.TO, new InternetAddress(to));
message.setSubject(subject);
message.setSentDate(new Date());
// Set the email message text.
MimeBodyPart messagePart = new MimeBodyPart();
messagePart.setText(bodyText);
// Set the email attachment file
MimeBodyPart attachmentPart = new MimeBodyPart();
FileDataSource fileDataSource = new FileDataSource(filename) {
@Override
public String getContentType() {
return "application/octet-stream";
attachmentPart.setDataHandler(new DataHandler(fileDataSource));
attachmentPart.setFileName(filename);
Multipart multipart = new MimeMultipart();
multipart.addBodyPart(messagePart);
multipart.addBodyPart(attachmentPart);
message.setContent(multipart);
Transport.send(message);
} catch (MessagingException e) {
e.printStackTrace();
private class SMTPAuthenticator extends javax.mail.Authenticator {
@Override
public PasswordAuthentication getPasswordAuthentication() {
String username = SMTP_AUTH_USER;
String password = SMTP_AUTH_PWD;
return new PasswordAuthentication(username, password);
}I will appreciate your help to solve this situation.
Regards,

Are you sure you're using the Sun implementation of JavaMail on RedHat? Some versions of
Linux come with the Gnu version of JavaMail included, which might behave differently.
If you turn on session debugging, what does the protocol trace show?
Are you sure you're sending the same file in all cases?

Yes I am using JavaMail 1.4 from SUN.

Yes. Below you will find the protocol trace.

Yes I am sure.

Good point. I will check it out!
