You create a multipart body and set the file

Expand|Select|Wrap|Line Numbers

  
 BodyPart messageBodyPart = new MimeBodyPart();

 Multipart multipart = new MimeMultipart();

//....

 // Set the normal text part 

 multipart.addBodyPart(messageBodyPart);

 messageBodyPart = new MimeBodyPart();

 DataSource source = new FileDataSource("yourfilePath.txt");

 messageBodyPart.setDataHandler(new DataHandler(source));

 messageBodyPart.setFileName(filename);

 multipart.addBodyPart(messageBodyPart);

You are uploading the file to the server right? You can use a ByteArrayDataSource instead of a FileDatasource if you are getting the file as a byte[].

If you have a the file in a byte[] on the server side then you don't need a file path. You would just use the ByteArrayDataSource which you create from the byte[]. How are you uploading the file to the server?

As I explained in your thread http://bytes.com/topic/java/answers/...variables-null
Read about how to upload files to the server side in java first. Google is your friend.
