[Jython-users] does PythonInterpreter look at the registry?

[John F. <jfa...@mi...>]

Hi guys! I am trying to embed Jython in a large multi-tier Java app. I am 
trying to figure out what I have to do to get it to pick up the python.path
setting from the registry. What I have done so far is:

 * change the registry to say:
python.path = f:\\jython-2.1a1\\lib    
 * the registry is f:\jython-2.1a1\registry
 * pass -Dpython.home=f:\jython-2.1a1 as a command line arg to the app
 * instantiate a PythonInterpreter
 * put my library, "minestar_admin.py" into f:\jython-2.1a1\lib.

Now, my theory on how it should work is that when I instantiate
PythonInterpreter it looks in the system properties for the python.home
setting. Then it looks in that directory for the file 'registry'. Then it
loads that file, giving it a value for python.path. Then it looks along
that path to resolve things. However, when I exec the line

import minestar_admin

I get:

Traceback (innermost last):
  File "<string>", line 1, in ?
NameError: minestar_admin

        at org.python.core.__builtin__.eval(__builtin__.java:245)
        at org.python.util.PythonInterpreter.eval(PythonInterpreter.java:102)

which suggests to me that PythonInterpreter can't find the file. Could
someone please tell me what is wrong with my hypothesis above? I read
the Javadoc for PythonInterpreter, and it said:

>public class PythonInterpreter extends java.lang.Object 
>
>The PythonInterpreter class is a standard wrapper for a JPython interpreter for use embedding in a Java >application.

Thanks for any help.
