Thanks Ikai.
It did NOT work before because I set the dataHandler before I set the
FileName.
Just have to set the FileName and then set the DataHandler.
attachment.setFileName("ticker.png");
attachment.setDataHandler(new DataHandler(mimePartDataSource));
Is this behaviour intentional?
Many thanks
Don
