How to get Subject from within Policy.implies()?

I have to create a dynamic (changeable at runtime) security environment, so I have extended Policy class and overridden implies method. I need to make decisions based onsubject. How can find it from within this method?

Is there already any Policy implementation that can do this(dynamic permission) for me. Or is there any way to manipulate Sun's PolicyFile permissions at runtime?

Regards
