[Jython-dev] jythonc "from blah import stuff, stuff" bug

[Chris M. <ch...@bo...>]

First of all, I love Jython!  I have done some amazing things with it in 
the two days of experience that I have :)

I have an application working in Jython, and I am currently trying to 
get the applet to work, as well.  I am using Jython 2.1a3 with JDK 
1.3.1_01 from Sun.

I did the following:

jythonc --core --deep --jar myapplet.jar myapplet.py

And it produced the appropriate jar file with all of the fixings, as 
expected.

However, when trying to invoke the applet with appletviewer (or in a 
browser plugin), I got the following:

    java.lang.NoClassDefFoundError: org/python/compiler/JavaMaker

I finally isolated it to this line of python code:

    from java.awt import Panel, Font, Button, Panel, Color, Label

Notice that 'Panel' is imported twice in that list.  That was causing 
the problem (but the error was not very helpful at all).  Once I removed 
the spurious Panel import, I stopped getting that particular error.

I am currently struggling with a different error, but the one above is 
clearly (IMHO) a Jython bug, and I figured I should let you guys know.
