I am trying to run the web app framework, the hello world program as
specified in the example but nothing shows up.

Here is the code for helloworld py

from google.appengine.ext import webapp
from google.appengine.ext.webapp.util import run_wsgi_app
class MainPage(webapp.RequestHandler):
    def get(self):
        self.response.headers['Content-Type'] = 'text/plain'
        self.response.out.write('Hello, webapp World!')
        application = webapp.WSGIApplication(
                                 [('/', MainPage)],debug=True)
        def main():
            run_wsgi_app(application)
            if __name__ == "__main__":
                main()

Here is the log when I start the server ..........dev_appserver.py
helloworld
