Hello,
 
I'm running NetBeans 3.34 with the Sun JDK/SDK version 1.4.1_01b, on a Win 2k box.  I'm trying to integrate Jython 2.1 into my test app.  I created a Frame where originally I tried starting the Jython interpreter when a button was hit.  I got the error dump shown below.  I did some Google searching and checked the Jython users mailing list archives, and saw some posts regarding Jython and multi-threading problems.  So I moved the code that tries to instantiate the jython interpreter into the static main() function that creates and shows the Frame.  Same error dump.  Does anyone know what to do here?
 
thx
