In the jython script.

If "foo.py" is a module that have been compiled with jythonc:

import java
class foo(java.lang.Object):
    def toString(self):
        return "foo.toString"
    def bar(self, arg):
        """@sig int bar(int arg)"""
        return arg + 1


then this jythonc compiled module can be used from a jython script by
importing it like this:

#import foo
import foo as fooClass
import new
foo = new.module("foo")
fooClass.moduleDictInit(foo.__dict__)

f = foo.foo()
print f.toString()
print f.bar(43)


The thing to notice is that a bare "import foo" will not import foo as a
module but it will import the java class. The 4 lines at the beginning
will wrap this java class in a module called "foo".

If you use this, keep in mind that it is a hack. You may be forced to
remove the hack when you upgrade to a later version of jython.
