[Engin Okucu]

This exce^tion is thrown because you don't have a correct method main() in your application,even if you don't have a method main you compile whithout problem but it will not guarantee you can run it :

public class abc {
public static void main(String args[]) {
System.out.println("now OK");
}
}
