Problem with Sending Mail

[Yurong Chen]

Hello,
I met a problem in sending email. I want to send a email with both body content and attachment content. I try the following code:

 public boolean sendFile(){
 
           try {
InternetAddress from = new InternetAddress(getFromAddress(), getFromName());
InternetAddress to = new InternetAddress(getToAddress(), getToName());
Properties props = new Properties();
props.put("mail.smtp.host", fieldSmtpHost);
// Create a mail session
Session session = Session.getDefaultInstance(props, null);
session.setDebug(true);
mail = new MimeMessage(session);
mail.setFrom(from);
mail.addRecipient(Message.RecipientType.TO, to);
mail.setSubject(getSubject());
//mail.setContent(getBody(), "text/plain");

int n=1;


Multipart mp = new MimeMultipart();

MimeBodyPart mbp1= new MimeBodyPart();
mbp1.setContent(getBody(), "text/plain");
mp.addBodyPart(mbp1,n);
                
                Enumeration efile=fileVector.elements();
                
while(efile.hasMoreElements()){
MimeBodyPart mbp=new MimeBodyPart();
fileName=efile .nextElement().toString();

FileDataSource fds=new FileDataSource(fileName);
mbp.setDataHandler(new DataHandler(fds));
mbp.setFileName(fds.getName());

mp.addBodyPart(mbp,++n);

}
fileVector.removeAllElements();
//new try


mail.setContent(mp);
mail.setSentDate(new Date());
Transport.send(mail);
} 
catch (MessagingException mex) {

mex.printStackTrace();
Exception ex = null;
if ((ex=mex.getNextException())!=null){
ex.printStackTrace();
}
return false;
}
catch (Exception exc) {

        }
return true;
   }
      } 

However, I received the email only with the attachment. I cannot find any body content in my email. Could anybody help me? Thank you in advance!
