[Jython-users] jythonc NullPointerException

[Kieran B. <ki...@br...>]

Can you help? I am getting the following stack trace from some jythonc'd 
jython code. The code works fine in jython, but when I turn it into a 
jar with command:
$ //c/jython-2.1a1/jythonc.bat -C c:/JBuilder4/jdk1.3/bin/javac.exe 
-core -jar TB2.jar TB2.py

I get a stacktrace on my awt actionPerformed:
def actionPerformed(self, e):
    conversation = WebConversation()
    request = GetMethodWebRequest( self.getURL() )
    response = conversation.getResponse( request )
    self.setHTML(response.getText())

The external classes I'm using are from httpunit.sourceforge.net.

If I just have:
def actionPerformed(self, e):
    self.setHTML("hi")

It would appear, just having the line:
conversation = WebConversation()

causes the stack trace. Can you help?
