Hello,

I was trying to freeze (actually web/servlet-ize, but that's besides the =
point) my Jython application, and failed - I must be doing something =
totally wrong. :-(.

Here's a short failure scenario:

-- module Main.py in root/current package --
# commented -- from amod.A import A
from bmod.B import B

B().bfunc()
-- end Main.py --

-- module A.py in package/directory apkg --
class A:
 def afunc(self):
  return "kermits"
-- end A.py --

-- module B.py in package/directory bpkg --
from apkg.A import A

class B:
 def bfunc(self):
  print A().afunc()
-- end B.py --

I also have 2 empty __init__.py files (one for apkg, the other for =
bpkg).

Now, "jython Main.py" works just fine ("kermits" is printed).
Here's the output from "jythonc --deep" at compile time:

-- start --
E:\projects\jytest\2>jythonc --deep Main.py
processing Main
processing bpkg.B
processing apkg.A
processing bpkg.__init__

-- end --

Next, we go to "./jpywork" and do a "java Main" and get:

ImportError: no module named apkg
-- end --

Taking a look at the ./jpywork directory shows that __init__-s (.java, =
.class and $_PyInner.class) have only been compiled for bpkg, but not =
for apkg.
I tried passing it multiple arguments to compile, but it then compiled =
it to a different "package level".

Now, if we uncomment the first line in Main.py to also "from apkg.A =
import A" it works just fine (but importing all modules from the main =
application seems an ugly hack). Nevertheless, that still seems to fail
"plain" modules that just have "functions" inside, with no classes (will
check once again on that).

Any comments will be very appreciated.

Best regards,
Juris.

P.S. I'm using Jython 2.1a1 and Sun's JDK 1.3.
