[Jython-dev] dependency problem with jythonc

[Kexx <ke...@in...>]

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__

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).


Any comments will be very appreciated.


Best regards,
Juris.

P.S. I hope this is on-topic for this list, since it _might_ be a =
jythonc bug. If not - let me know and forgive me this time :-).
