You are right Robert. The classpath was the problem. Now it works. Thanks a
lot.

Maybe try sys.add_package("javax.naming"), (if you haven't already).

//import this
import org.python.core.PySystemState;

//before trying to import a class in javax.naming, do this
PySystemState sys = Py.getSystemState();
sys.add_package("javax.naming");

//Then...
interp.exec("import javax.naming.NamingException")

The org.python.util.PyServlet.java file that comes with Jython is a good
example of using sys.add_package as well as sys.add_extdir and
sys.add_classdir.  You may be seeing something similar to what required
PyServlet to use the add_package calls.
