I too have been looking for this exact same solution, ive downloaded this .jar programme it seems to do something but leaves an ampty out.txt file - any ideas? Ive got internet connection and it does the same thing with the test in.txt file so its not the formatting of the in.txt file.
Bc.i changed their API you can either use the source and change it to your needs or use the curl version I wrote a bit later[1] thats working with the blocktrail.com API.

Im also unsure which file in the source code I need to amend or how to build/compile it when I have. I'm guessing its the main.java in the src folder? Do I literally have to change the blockchain.info address to an another address?
Happy to send you a donation if you can get this working for me.
