Multiple Attachment

[jenny soft]

Hi,
I am doing sending mail with attachment,for a single attachment i am using the following code

if(filename!="")
           {
  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);
             }

for multiple attachment any other code is there or could i include any lines
in the above code.
Thanks in advance.
