Strange, simple Jython problem

[Oliver Rutherfurd]

Hi Chris,

Just a stab, but are you trying to call instance methods of classes without
creating an instance of the class?

    Jython 2.1 on java1.4.1 (JIT: null)
    Type "copyright", "credits" or "license" for more information.
    >>> from java.lang import Math
    >>> print Math.random()
    0.4088084432947816
    >>> from java.util import Vector
    >>> print Vector.size()
    Traceback (innermost last):

      File "<console>", line 1, in ?

    TypeError: size(): expected 1 args; got 0

    >>> v = Vector()
    >>> print v.size()
    0

-Ollie
