Thanks for answering :) I was quite desperate as nobody has answered my=20=

previous posts on jython-users, and it is not the first time it=20
happens.. So I did not found any alternative to direct posting to=20
jython-dev... I mentioned (in PS) that I was using jython-2.1a3, my=20
current JDK is MacOS X JDK 1.3.1- I have now switched to jython 2.0

Yes, but I have not found anything... It's hard to make a query on that.

The files are Java compiled files put in a jar. The sys-package-manager=20=

finds the jar so this should be ok. As I said I can make a dir() on the=20=

package name and it lists me the actual content of the package, but it=20=

tells me this attribute error telling there is no Application attribute=20=

in the package. The class is public, this is not a protection problem.

After some experiment, putting my jar in /Library/Java/Extensions which=20=

is the jre/lib/ext equivalent and starting jython interpreter I was able=20=

to do :

Jython 2.0 on java1.3.1 (JIT: null)
Type "copyright", "credits" or "license" for more information.
 >>> import net.sourceforge.spedit.app
 >>> net.sourceforge.spedit.app.Application()
 >>> ...everything went fine

(note: I switched back to jython 2 to see if the problem was still =
there)

Afterwards I tried another way, removing my package from the Extensions=20=

and starting the jython interpreter with -cp  SPEdit.jar, which is the=20=

package containing my classes. So I made the following:

Jython 2.0 on java1.3.1 (JIT: null)
Type "copyright", "credits" or "license" for more information.
 >>> import net.sourceforge.spedit.app
 >>> net.sourceforge.spedit.app.Application()
Traceback (innermost last):
   File "<console>", line 1, in ?
AttributeError: java package 'net.sourceforge.spedit.app' has no=20
attribute 'Application'

This puzzles me really, because as I said:
 >>> dir(net.sourceforge.spedit.app)
['Application', 'AuthorDisplay', 'DBView', 'NavigationTree', '__name__']

So jython actually knows the package.. Any clues?
