Keep in mind that python class can't overload a method name. Instead it
can define different numbers of arguments to the same method. Since the
python "showData" method will subclass both java showData methods, you
will have to figure out which invocation that occured. Something like:

	def showData(self, inName, inValue=None):
		if inValue == None:
			# The "inName" arg is actually a Data instance
			Test.Callback.showData(self, inName)
		else:
			print inName
			print inValue

As you can see, implementing an overloaded java method in python is not
a situation where jython shines.
