Jython run scripts problem (2.2.0a0 on Mac OSX 10.3.8)

[scott]

I installed darwinports and did a "sudo port install jython"

-------------------------

scott$ which jython
/opt/local/bin/jython

-------------------------

Jython works in interactive mode as shown below:

-------------------------

pyprogs$ cd hotbits/
hotbits$ ls
flips50.py jythoninstall.py randomX randomflip.py
hotbits$ jython
Jython 2.2a0 on java1.4.2_05 (JIT: null)

# Truly random (radioactive decay triggered) coin flip
from randomX import randomHotBits
r = randomHotBits()
if r.nextByte() < 0: .... print 'tails'
.... else:
.... print 'heads'
....
tails

--------------------------

Jython *doesn't* work if I save the above as a script and try to run it.
It refuses to run the script and simply starts up in interactive mode:

---------------------------

hotbits$ jython randomflip.py
Jython 2.2a0 on java1.4.2_05 (JIT: null)

---------------------------

Question:
How can I run scripts as expected (outside interactive mode)?

Thanks in advance.

Looks as if the jython shell script does not pass your scriptname as
argument to the interpreter class.

Mine (on linux) looks like this:

"/usr/lib/j2se/1.4/jre/bin/java" -Dpython.home="/home/deets/lib/jython-2.1"
-classpath "/home/deets/lib/jython-2.1/jython.jar:$CLASSPATH"
"org.python.util.jython" "$@"

Note the "$@" - that passes all additional arguments.
