Send Email Attachement using byte[] with Java-Mail

Question

I have a byte array wich i wish to add as an attachement to an email i am sending.

Unfortunally i can't find how to attach it as a byte array, the solution i have uses disk files (which i dont want since i dont want to write the byte array just so i can attach it).

I've found one solution that involves creating an object that extends DataSource and use this as a wrapper for the byte array and then feed that to the MimeBodyPart.

Anyone know of a better solution?

Answer 1

Creating a DataSource is the right approach. You don't have to write your own, though. Just use the ByteArrayDataSource from JavaMail.
