Jython + propertyChangeListener?!?!

[Matt Newcomb]

G'day,

Hi. I'm new to jython/python and am trying to interface a jython
script with some java code that produces property change events.
Here's the jython code:

import sys;
from javax import swing;
from java.beans import PropertyChangeListener;
from gov.nasa.gsfc.irc.instrument import InstrumentModelProvider;

class irchooks(PropertyChangeListener):

def propertyChange(self, e):
print "Property Change:";
print e;
print self;

def __init__(self):

self.modelProvider = InstrumentModelProvider.getInstance()
self.model = self.modelProvider.getInstrument("Detector")

print "Sample Rate: "
print self.model.getFramePeriod();

self.model.addPropertyChangeListener(self);

print "Generate a property change event"
self.model.setFramePeriod(0.215);

Then when I try running this code from the application ( via the bean
scripting framework ), I keep getting these errors:

Sample Rate:
0.001
Traceback (innermost last):
File "<string>", line 37, in ?
File "<string>", line 33, in __init__
TypeError: propertyChange() too many arguments; expected 1 got 2
Exception in backgrounded command procedure: PropertChangeTest
exception from JPython: Traceback (innermost last):
File "<string>", line 37, in ?
File "<string>", line 33, in __init__
TypeError: propertyChange() too many arguments; expected 1 got 2
: Traceback (innermost last):
File "<string>", line 37, in ?
File "<string>", line 33, in __init__
TypeError: propertyChange() too many arguments; expected 1 got 2

Huh? Any ideas?

Thanks.
