public class Logger

extends java.lang.Object

This class provides a uniform way to produce logging printouts in a device dependent way. More in details if you are running JADE in a Java 2 standard edition environment or in a PersonalJava environment (through the LEAP add-on) a call to Logger.println() simply results in a call to System.out.println(). On the other hand if you are running JADE in a MIDP environment (again through the LEAP add-on) printouts are redirected so that they can be later viewed by means of the jade.util.leap.OutputViewer MIDlet included in the LEAP add-on.
