Nope.  Python added rich comparison methods(__eq__, __gt__, __le__ and
so on) in 2.1, and Jython's str uses those in 2.2 instead of __cmp__.
CPython exhibits the same behavior.  You can get equivalent
functionality to __cmp__ with the builtin cmp function: cmp('a', 'b')

Thanks Charlie

cmp() works ok.  :-)
