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

[Chris W. <cw...@am...>]

I have python.path set to ~/lib/python and my CLASSPATH set to . and I
 cd to src before I start up jython.

Here is what I got in my path.

src/foo/python/Foo2.class
src/foo/python/Foo2.java
lib/python/foo/__init__.py
lib/python/foo/__init__$py.class
(See attach tar for the source code.)

__init__.py contains one jython class called Foo

Here is what I did.

~/src% export CLASSPATH=.
~/src% jython
Jython 2.0 on java1.3.1 (JIT: null)
Type "copyright", "credits" or "license" for more information.
>>> from foo import *
>>> dir ('foo')
[]
>>> Foo()
<foo.Foo instance at 7127716>
>>> Foo2()
Traceback (innermost last):
  File "<console>", line 1, in ?
NameError: Foo2
>>> import foo
>>> foo.Foo2()
Traceback (innermost last):
  File "<console>", line 1, in ?
AttributeError: module 'foo' has no attribute 'Foo2'
>>>

As you can see, Foo was created correctly, but when I try to create Foo2,
it said module 'foo' has no attribute 'Foo2'.  It looks like that it's not
backtracking in this case.  Is this normal?

Thanks for any help.
