-------------------------------------------------------------
I tried splitting the inner class and the controller script like this:
runHelloBxml.py
{code}
#!/usr/bin/env jython
from org.apache.pivot.wtk import DesktopApplicationContext
from java.lang import Runnable, Exception as Ex
from javax.swing import SwingUtilities
import sys,subprocess,os,re, traceback
from HelloClasses import HelloBXML
class Task(Runnable):
def __init__(self, argv):
self.argv = argv
def run(self):
DesktopApplicationContext.main(HelloBXML().class, self.argv)
if __name__ == "__main__":
try:
SwingUtilities.invokeAndWait(Task(sys.argv[1:]))
except:
traceback.print_exc(file=sys.stderr)
sys.exit(192)
{code}
And the inner class, now a regular class, module file: HelloClasses.py:
{code}
from org.apache.pivot.beans import BXMLSerializer
from org.apache.pivot.wtk import Application
class HelloBXML(Application):
def __init__(self):
self.window = None
self.bxmlSerializer = BXMLSerializer()
def startup(self, display, properties):
self.window = self.bxmlSerializer.readObject(self.class,
"hello.bxml")
self.window.open(display)
def shutdown(self, optional):
if self.window != null:
window.close()
return False;
def suspend(self):
pass
def resume(self):
pass
{code}
Somehow JYTHON doesn't get the Class:
