    def ViewI(self):
        return "Hello"
 --

and restart wsgi - server : like this:
 if __name__=='__main__':
    PROJECT_DIR = os.path.dirname(os.path.abspath(__file__))
    print PROJECT_DIR

    sys.path.insert(0, os.path.dirname(PROJECT_DIR))
    PROJECT_NAME = PROJECT_DIR.split('/')[-1]
    print "---"
    print PROJECT_NAME

    os.environ['DJANGO_SETTINGS_MODULE'] = "%s.settings" % PROJECT_NAME

    port = 8000
    application = LadonWSGIApplication(['MYGateway','Calculator'], ['.'])
    server = wsgiref.simple_server.make_server('', port , application)
    server.serve_forever()

and try to use new function

The bug is not in Ladon but the way you use strings. When you ladonize a method to use unicode you must be sure to return that type:

# -*- coding: utf-8 -*-
from ladon.ladonizer import ladonize

class TaleoGateway(object):
        @ladonize(rtype=unicode)
        def ViewI(self):
                return unicode("Hello")

ViewInterview and RequestInterview both should return unicode strings but they don't. The add function should work. It would be nice if you sent the exception that Ladon produces.
