It did, though, force a blog post out of me, which is not a bad thing! I've updated the post.

Switzer, II Fri, 09 Feb 2007 15:54:40 +0000 http://blogs.sanmathi.org/ashwin/?p=61#comment-161 As Robi's blog stated, I was the one that asked him for the code. The problem I had was that I was trying to use the JavaMail API to send an attachment from a binary object already loaded in to memory. The JavaMail API requires some kind of class derived from the DataSource class in order to generate the attachment in the e-mail. JavaMail v1.3.1 (which is what CFMX uses) only comes with a FileDataSource class--which requires the binary data be written to disk. So, I was trying to find a quick method to search ColdFusion to see what classes I had access to. I could have written a ByteArrayDataSource (which is what most sites recommended for using w/JavaMail and binary data already loaded into memory,) but I didn't want to introduce an outside dependency. So, by searching through the JARs in the CFMX directory, I was able to find the OctetStreamDataSource in the axis.jar which I was able to leverage.

I just tested it on jExcel JAR file and it found it quite well. This will be excellent for debugging. Nice tip! I just tested it on jExcel JAR file and it found it quite well.
