Urgent deadline - Please help - Linux serialization problem

Question

Hi -
I have a presentation on Wednesday morning of my program for my dissertation. I developed the whole thing in windows - it all works great... but the demo is on a Linux machine. Fortunately I tested today in Linux. I have a real problem. I want to save out a class instance. This code works fine in Windows:
                    String project_name = f.getAbsolutePath() + "/" + directory_name + ".oll";
                    ObjectOutputStream out = new ObjectOutputStream(new FileOutputStream(project_name));
                    out.writeObject(mainCanvas);
                    out.flush();
                    out.close();The problem is that in Linux I just don't get anything saved. There is nothing there at all. No file is saved. I cannot work this out and am in a panic. Any help really appreciated.
Olly

bufferedwriter = new BufferedWriter(filewriter);
} else
File file1 = new File("/home/usr2/barcwas1" + s2 + s1);
boolean flag1 = file1.createNewFile();
filewriter = new FileWriter("/home/usr2/barcwas1" + s2 + s1, true);
