QtJambi and Jython

Question

I'm trying to get QtJambi and Jython to play nice together. Here's what I'm doing as a test:

>jython -Dpython.path=./qtjambi-4.5.2_01.jar:./qtjambi-linux64-gcc-4.5.2_01.jar:.
Jython 2.2.1 on java1.6.0_18
Type "copyright", "credits" or "license" for more information.
>>> from com.trolltech.qt.gui import *
>>> dir(QApplication)

>>> QApplication.initialize([])

java.lang.NoClassDefFoundError: java.lang.NoClassDefFoundError: Could not initialize class com.trolltech.qt.gui.QApplication

I tried compiling and running a simple "Hello World" QtJambi example and it runs fine.

Any ideas of what I'm doing wrong?

Thanks

Answer 1

native libs !

i think there are some shared-libs, and maybe the java vm couldn't find them.

ist there a bin dir ? it should be on the path /not the classpath !

have a look at how-to-add-native-library-to-java-library-path
