It's been quite some time since I have done something with Java, and with no practice you get out of shape :-)
I would like to make a small program with Java to extract a six-digit number from a pdf document. This number is always present in the same position, for example after the word "test", and in the same row. Eventually, this number would replace the current filename of the pdf document.
I would appreciate any hints on a good pdf extraction package and maybe some other hints that you might offer to help me start off.
