AttributeError: class 'jnios.os' has no attribute 'fork' ---- what!!??

[shari]

Sorry if this sounds simple, but I've just started using jpython.

I want to call a python script from java.  I thought it would be
simple!

Within my java code I am using: 

  PythonInterpreter pInt = new PythonInterpreter(); 
  pInt.execfile(".\\Test.py");

To call a python script containing:

  self.pid = os.fork()

At first I got the error "os has no attribute pipe", which I solved by
using 'jnios-1.7' to replace Lib\os.py.  My error then mutated into
the following:

  AttributeError: class 'jnios.os' has no attribute 'fork'

So I can't use popen2.py or os.fork().  I'm now at a complete dead
end, has anyone got any clues?

Cheers,
Shari
