There are two APIs related to your requirements, the method JCSystem.getAID and JCSystem.lookupAID.
As far as I remember JCSystem.getAID can get the AID of applet inside one instance.
The method JCSystem.lookupAID get the AID from another applet.
Any detail descriptions please refer to Specification Doc, Application Programming Interface.
