Hi Paul Stevens:
Thanks for your responses first.
the Test.java is very simple.
public class Test{
public static void main(String[] args){
System.out.println("hello,world");
}
}

Hi Dragon,
I'm going to move this over to Other Java API. This forum is only for questions directly relating to the SCJP exam.
