Hello all. I've seen many many posts concerning creating attachments to email messages. I have been able to do this without too much problem.
However, binary attachments always show up corrupted. Plain text attachments are fine. For example, a .doc attachment will be recognized by Word, but if you attempt to open it up, I get a 'Invalid path or filename' error. The primary difference between my situation and one that I have seen posted many times here is that I am not using either a File data source nor a Url data source. I have blobs stored in Oracle and simply have been attempting to create a new MimeBodyPart using the byte[] array I get back from Oracle and a blank InternetHeaders. I initially belived this to be a Content-Type issue, but I have attempted setting the Content-Type for the InternetHeaders object without success.
I know that the byte[] comprising the documents are OK; if I take an intermediate step and write the bytes out to the OS, then use a file data source to create the attachment, I can send it out and the client can read it no problem.
Can anyone help?
Thanks!

Sampe Code below:
for (int z=0;z<attachments.length;z++){
SendMail.Attachment currentAttachment = attachments[z];
InternetHeaders blankHeader = new InternetHeaders();
MimeBodyPart attachmentBodyPart = new MimeBodyPart();
blankHeader.addHeader("Content-Type", currentAttachment.getContentType().toLowerCase());
attachmentBodyPart = new MimeBodyPart(blankHeader, currentAttachment.getByteContents());
MimePartDataSource source = new MimePartDataSource(attachmentBodyPart);
attachmentBodyPart.setDataHandler(new DataHandler(source));
attachmentBodyPart.setFileName(currentAttachment.getFilename());
multipart.addBodyPart(attachmentBodyPart);
}
Again, everything appears to work fine except that I cannot open the files when they arrive.
