[Jython-users] help with jython and creating an applet

[Scott H. <sl...@ho...>]

I am trying to create a jython applet.  I am running Windows 2000 pro =
with Sun's JDK 1.3.1 and I have tried both Jython 2.0 and 2.1a3.  My =
code runs fine when I execute it with Jython, but when comiling it into =
the applet with (I have only one .py file named dlClient.py):

jython --compiler javac --all --jar downloadClient.jar *.py

The .jar is created, but it gives a warning about using a deprecated =
API.  Then when I try to execute it with the appletviewer, I get an =
error that says:

java.lang.ClassCastException:  dlClient

Can anyone tell me what I am doing wrong?  Below, I have posted the code =
for the .py file as well.

from java import applet
from java.awt import Color,Label,Button,GridLayout,Label
from urllib import urlretrieve
import time

class downloadClient(applet.Applet):
    def init(self):
 try:
  self.setLayout(GridLayout(0,1))
  self.title =3D self.add(Label('Download Test', Label.CENTER))
  self.title.setBackground(Color.blue)
  self.title.setForeground(Color.white)
  self.add(Label('Beginning Download ...'))
  # this file is 45.7k in size
  self.startTime =3D time.time()
  rValue =3D urlretrieve("http://localhost/reports/detail.pdf")
  rValue =3D urlretrieve("http://localhost/reports/detail.pdf")
  rValue =3D urlretrieve("http://localhost/reports/detail.pdf")
  self.endTime =3D time.time()
  self.elapsedTime =3D int(self.endTime - self.startTime)
  self.kPerSec =3D int(137.1/self.elapsedTime)
  self.add(Label('Download Complete'))
  self.add(Label('Amount Downloaded:  137.1 KB'))
  self.add(Label('Time Elapsed:  ' + str(self.elapsedTime) + ' =
seconds'))
  self.totalSpeed =3D self.add(Label('Total Speed:  ' + =
str(self.kPerSec) + ' KB/Sec'))
  self.totalSpeed.setBackground(Color.yellow)
  #self.totalSpeed.setForeground(Color.blue)
 except:
  pass

if __name__ =3D=3D '__main__':=20
    import pawt
    pawt.test(downloadClient())
