How does the Java Card simulator work? (Using NetBeans)

Question

Hi,
I'm using NetBeans and am trying to simulate:
Someone powering up the card, saving a value, and powering down... And then they power it up again, get the value, and power down.
When I edit my APDU script to do the second part, the value I entered the first time is never stored, which probably means that when I 'run' my code, my application is loaded and everything is initialized again.
How do I edit NetBeans to not install the application every time I hit 'run'? And not to initialize the values, so that when i power it up again, I can get a value stored in a previous running of a script?
When I use powerup, powerdown and then powerup again, NetBeans doesn't powerup the simulator the second time. So understanding the Java Card Simulator would also help... where it is, how it runs, what options it runs with, etc.

Hi Shane,
I have not read anywhere else that the JC3 cards are not available, thank you so much for that tip! I am not doing it for research, but I am working on this alone and will have to deploy a card later on. I will be getting all the right versions now.
I'll ask the question then, using just the JCDK:
If I want to save a value on the card, and then need it at a later time, how do I go about it. Do I do the following?
(1) Install the application on the card. (I know how to do this)
(2) Run the simulator using -o "eeprom data filename"
(3) Save the value using the APDU calls and Java code on the card + close connection.
Code:
public class MyApp extends Applet {
    private static byte[] data = {0x00, 0x00, 0x00};
    // Install method, method to register, process method that can call saveData or recallData, etc
    public static void saveData()
       // code to change data
       data = {0x01, 0x01, 0x01};
    public static byte[] recallData()
       // code to return data
       return data;
}(4) Run the simulator using -i "eeprom data filename". get the value using recallData().
Will selecting the app not make data initialize to {0x00, 0x00, 0x00} again?
If I know this is the correct way of going about it, then I can work towards it getting done.
From other examples I can see that this is probably the way it should work, but my data array always returns as {0x00, 0x00, 0x00}.
