How to store data in JavaFX 1.2 Mobile with Storage and Resource API

Question

I'm need to store some numbers and strings in an application that will be deployed in a HTC HD2 device with JavaFX 1.2 When run on desktop, everything works perfectly. But after being installed in the device, the application won't store data in files. I thought JavaFX was able to do that, according to its documentation (http://download.oracle.com/docs/cd/E17802_01/javafx/javafx/1.2/docs/api/javafx.io/javafx.io.Storage.html)
I do it like this (just the part that stores integers)
public var availableGifts : Integer[] = [0,0,0];
var highscoresFile = Storage {
source: "AvailableGifts.txt"
public function writeConfiguration() {
try {
var resource : Resource = configurationFile.resource;
var outputStream : DataOutputStream = new DataOutputStream(resource.openOutputStream(true));
outputStream.writeInt(availableGifts[0]);
outputStream.writeInt(availableGifts[1]);
outputStream.writeInt(availableGifts[2]);
outputStream.flush();
outputStream.close();
println("Data stored!");
} catch(ex : IOException) {
ex.printStackTrace();
The application is self-signed, just in case. But it won't store data in the mobile device... I need some help with this!

Agh, the problem is not in how data is stored, because it IS being stored. The problem is that inputstream.available() seems to always return 0 in the mobile device, so the file seems to be empty.
But that's a different problem.
