Jython Question

[Jesper Olsen]

With Jython it is easy to access existing Java classes
- I tried the random number example at
http://www.jython.org/docs/usejava.html´.

But I failed to create an example myself. Is it only packages that
can be imported?

This is a java class that I would like to access 

class World {
    public World() {
        System.out.println("constructing World!");
    }

    public void hi() {
        System.out.println("Hi World!");
    }
}


from jython - however I get an exception when try to instantiate this
class
in jython. Can anyone point out what is wrong in this example?

prompt% jython

Type "copyright", "credits" or "license" for more information.
>>> import World
>>> w=World()
