We are happy to announce the release of jCardSim GP. This is a module for jCardSim that implements Global Platform specification.
Using jCardSim with the commercial module, you access the industy standards: Java Card and Global Platform. Thus, now you can use GP API for working with secure channels, interacting with GP registry and other functions defined in the standard. We would like to note that the latest version of jCardSim implements Java Card 3.0.5 Classic Edition, so you have got the right solution, which makes developing applets for the wide-spread versions of the platforms easy.
