java process PDF into DOC

PDF to DOC

Before someone to share my part of the technical documentation, but it is the PDF. It turned himself wanted DOC files in an editor. Many found online surcharge, I thought it would also need the junk fees. So do yourself a settlement.
I have been pro-test non-toxic, taken directly!
Do not say, on the code!
