[Jython-users] Multi-module embed, how to import sibling modules?

[Brad C. <bk...@mu...>]

I have 3 python modules

a.py, b.py and c.py

b.py has

from c import C

I use jythonc with --package com.MurkWorks.FTPD

The Java app can instantiate com.MurkWorks.FTPD.b okay.

But when b tries to import class C from module c, it fails with

importerror: cannot import name c

--

So then I tried changing b.py to use

from com.MurkWorks.FTPD.c import C

This also fails with a similar import error.

What's the proper method for multiple modules to load each other when 
compiled with the --package option?

I couldn't find an example of this in Demos.

There isn't any at the moment. The --package option is currectly most
usefull when using the --deep option. That way the compiler knows that
module "c" is in fact found as com.MurkWorks.FTPD.c. When you try to use

  from com.MurkWorks.FTPD.c import C

you are hit by the problem that python modules can't be found as java
classes in simple directories, only as modules in python packages (a
directory with an __init__ module).
