How to build jCardSim from source?
We would like to say great thanks for everybody who was on our session at JavaOne Russia 2013, for all who help us to develop and maintain this project! It was a pleasure to see great guys who are using our product for study purposes and for enterprise needs. As it turned out, one of the market leaders (STK/DSTK, USSD and (I)CB technologies) in Russia and CIS use jCardSim. We are very satisfied with this result. It was a very hard road and now we understand that all this not for nothing. Thanks again!
