When does an Applet display a warning dialogue?

Chaps,

I'm running Java 2 on Windows 95.

When does an Applet display a Warning dialogue?

The following Applet code causes a warning dialogue to pop up:

Properties props = null;
Frame f = new Frame("To print");
f.setSize(200, 300);
f.show();
PrintJob job = Toolkit.getDefaultToolkit().getPrintJob(f, "Print1",
props);

The dialogue asks the user's permission to print - which is exactly what
I want.

However the following generates an exception:

BufferedWriter bw = new BufferedWriter(new FileWriter("Foobar.txt"));
bw.write("Good morning Sun\n");

How can I find out which calls will generate exceptions, and which will
raise a warning dialogue?

Is it possible to change this behaviour?

Many thanks in anticipation,
