Most common cause of "java.lang.NullPointerException" when dealing with XMLs?

Question

My strongest lead is that the code who deals with the incoming XMLs is actually receiving an invalid/incomplete file hence failing the DOM parsing. Any suggestions?

Answer 1

Incomplete file is definitely the place to start looking. I'd print out the file right before the point you parse it to see what's getting sent to the parser. If it's incomplete it will be obvious. If it's invalid, you'll have a little searching to do.
