I tried the symlinks before and then installed the older library
(libstdc++-2-libc6.1-1-2.9.0
In both cases when I try to run the following program:

---
/*
Hello.java
*/
import java.awt.*;

public class Hello extends Frame {
  public static void main(String argv[])
  {
    new Hello();
  }
  Hello() {
    Label hello =
             new Label("Hello World");
    add(hello, "Center");
    setSize(200, 200);
    setVisible(true);
  }
}
---
javac Hello.java
java Hello

Then
the box with Hello World appears but I got the following message:

''
2002-12-10 18:19:48 java.util.prefs.FileSystemPreferences$3 run
WARNING: Could not create system preferences directory. System preferences
are unusable.''

The same message appears when I run 'appletviewer something.html'.

Any clue?
