[Jython-users] TypeError on Macs?

[Peter B. <bri...@ma...>]

Hi!
I've got a number of java .class files that I compiled from jython source
code. Everything works fine under Linux and Solaris, but when I tried to
run the same code on a Mac G3 (with the latest version of MRJ/SDK), I got
the following error message:
> Java Traceback:

It appears that the line that caused the error looks like this:
	b=java.awt.Button('Label',actionPerformed=self.someMethod)

I also installed jython on the Mac, and when I run the jython code via
jython (without compiling it to .class files first), I don't get an error
message, but nothing happens when I click on the buttons. Very confusing... 

Does anyone have any idea what's going on here?
Thanks,
