Serialisation problem

Hi,
I'm making a 2D Minecraft clone, and yes, that's very original.
I'm trying to serialise the blocks now, but I get an exception.
This is the code I'm using to serialise the blocks:
(part of the Chunk class)
- void saveBlocks() {
- try {
- for (int x = 0; x < Width; x++) {
- for (int y = 0; y < Height; y++) {
- File f = new File(+0+"_"+0+".bl");
- if (f.canWrite()) {
- FileOutputStream fileOut = new FileOutputStream(f.getAbsolutePath());
- ObjectOutputStream out = new ObjectOutputStream(fileOut);
- out.writeObject(blocks[x][y]);
- out.flush();
- out.close();
- fileOut.flush();
- fileOut.close();
- println("XXX SUCCES XXX");
- }
- else {print(".");}
- }
- }
- }
- catch(Exception i){
- i.printStackTrace();
- }
- }
And this is the exception:

What am I doing wrong here? I didn't even know my class implemented "com.jogamp.nativewindow.awt.AWTGraphicsConfiguration".
