how to use gtk/pywebkitgtk in jython?

Question

In installed standalone jython on my ubuntu 12.04, run it, but if I try to import gtk, I get no module named gtk when in python console it works.

Update:

I have done

>> sys.path.insert(1,"/usr/lib/python2.7/dist-packages/gtk-2.0")

and

>> sys.path.insert(1,'/usr/lib/python2.7/dist-packages")

and now is is

    from glib._glib import *
ImportError: No module named _glib

when:

argon@vprime:/usr/lib/python2.7$ find | grep _glib
./dist-packages/gi/_glib
./dist-packages/gi/_glib/option.pyc
./dist-packages/gi/_glib/option.py
./dist-packages/gi/_glib/_glib.so
./dist-packages/gi/_glib/__init__.pyc
./dist-packages/gi/_glib/__init__.py
./dist-packages/glib/_glib.so
./dist-packages/twisted/internet/test/test_glibbase.pyc
./dist-packages/twisted/internet/test/test_glibbase.py
./dist-packages/twisted/internet/_glibbase.py
./dist-packages/twisted/internet/_glibbase.pyc
./dist-packages/_dbus_glib_bindings.so

so, glib/_glib is under dist-packages and I have no idea what is wrong...

Not all modules are compatible between Jython and CPython (the standard Python interpreter). In particular, modules that are compiled to native bytecode, generally written in C/++ (or with Cython), cannot be loaded in Java, because it uses its own Virtual Machine (JVM) which cannot understand native bytecode.

Many native/binary modules in CPython will have a name prefixed with an underscore, like _glib above.

You have at least two options:

Use Jython and a Java GTK package.
Use CPython, and if you need to talk to Java, use one of the packages that interface between CPython and the JVM (e.g. jpype, py4j).
