Save the state of an Simulator

[frankmorgner]

I'd like to save the state of a Simulator with its loaded/initialized applets persistently to load them later. Unfortunately, the simulator is not serializable by ObjectOutputStream so that the following does not work on Android:

FileOutputStream fileOut = this.openFileOutput(filename, Activity.MODE_PRIVATE);
objectOut = new ObjectOutputStream(fileOut);
objectOut.writeObject(object);

I also tried Google's Gson without success:

FileOutputStream fileOut = this.openFileOutput(filename, Activity.MODE_PRIVATE);
fileOut.write(new Gson().toJson(object).getBytes());

Do you have any idea how to do this? Is there a built-in mechanism?

We are working on the implementation of the transactional EEPROM in jCardSim, that will meet JavaCard standard. Unfortunately, the serialisation mechanism is not suitable for saving jCardSim’s state, not only from technical point of view, but also because of the architectural principles. We will definitely let you know once it is ready

Thanks for looking into it!

In the meantime, a solution as described in this pdf (pages 32 and following) and implemented in this file might work for you.

unfortunately re-personalizing is not generally applicable

@licel, I just realize it's been one year this is open. Did you make any progress or do you need more details?
