Re: [Jython-dev] package resolution for jython package and Java package

[Samuele P. <pe...@in...>]

Hi.

It was just a pilot error <wink>.

Your java class is foo.python.Foo2, you can't get at it as foo.Foo2 in any
case.

Let's see and clarify some other points:

>>> dir ('foo')
[]

I think you meant dir(foo), dir('string') returns always [].

Then:

Jython 2.0 on java1.3.0 (JIT: null)
Type "copyright", "credits" or "license" for more information.
>>> from foo import *
>>> dir() # current namespace binding names
['Foo', '__doc__', '__name__']
>>> # dir(foo) will fail
>>> Foo()
<foo.Foo instance at 5691336>
>>> python.Foo2() # fails
Traceback (innermost last):
  File "<console>", line 1, in ?
NameError: python
>>> # but
>>> import foo
>>> dir(foo)
['Foo', '__doc__', '__file__', '__name__', '__path__']
>>> # jython backtracks
>>> foo.python.Foo2()
foo.python.Foo2@5d5681
>>> ^D

Worth to notice: with respect to from import * and dir a python package
behaves the usual way even when it shadows a java package, making it work
differently will mess up jython code without a real gain: in any case, from 
import * and dir nice features with java packages are intended for explorative 
interactive use, not for production time. On the other hand
jython backtracks properly to the java package.
