Mail attachment

Hi,

I already have the binary content for my attachment - it is a PDF file and it is held in the byte array listed below (called content). But when I try to send the mail using JavaMailSenderImpl I get the exception listed at the bottom.

My problem is, I dont see another interface method call that is appropriate for me ... I really dont want to save the byte[] to disk, just so I can passin a java.io.File instance...

Has anyone else come across this?

byte[] content = someByteArrayWithContent;

ByteArrayInputStream inputStream = new ByteArrayInputStream(content),

InputStreamResource isr = new InputStreamResource(inputStream);

helper.addAttachment(attachmentName, isr);

There was quite a long email thread on this subject recently which may help:
