Yes, I believe we can get the Java ClassAd source code to you. I believe 
the only real issue is that no one has packaged it up yet. I will try to do 
this within a couple of days and get it to you. Can you receive large 
attachments in email?

I asked the Java developer (who isn't yet on this email list) about the 
above question, and he wrote:
