[Jython-dev] JPython in a Java Applet with java PlugIn

[Thomas R. <t.r...@co...>]

Hello,

I've a java applet that runs with the Java PlugIn (JDK1.3). The applet is
(RSA-)signed an has all permissions. Within the applet I tried to execute a
jpython command (print "hello") with the exec-method of PythonInterpreter.
The exec-method causes an java.lang.NoClassDefFoundError:
org/python/core/PyFunctionTable. I delivered the python.jar with the applet
and I'm able to intstantiate the PytonInterpreter and any class of
org/python/core in the applet without problems.

Could somebody help me??

with kind regards
Thomas
