Re: [Jython-users] Calling methods in Java Superclass--Newbie

[Aurelien M. <aur...@fr...>]

You got an error because in your script, obj2 is not an instance of the =20=

java class ImportTester, but a reference to the class; it's a common =20
mistake in python. You must type:

	obj2 =3D ImportTester()

and it should work.

	Aur=E9lien

(not: the error message said you that if you want to call a method of a =20=

non-instanciated class, you must provide at least one argument: a =20
instance of this class)
