uwsgi error python application not found
===

I've configured my nginx server with uwsgi and python and when I try to run my python application by hitting the url in my browser, the browser returns the message, uwsgi error python application not found. 

This is what my uwsgi log looks like:

    *** Starting uWSGI 1.0.4 (32bit) on [Tue Jul 31 15:25:04 2012] ***

uwsgi and nginx is invoked from my virtualenv root using

    bin/uwsgi -p 2 --socket  127.0.0.1:8807 --module index --pythonpath ironjob/ai -d log/uwsgi_ai.log
    bin/nginx -p ./ -c ironjob/etcs/production/nginx.conf
~                                                                 

this is my nginx.conf file
    
    server {
        listen      8090;
        server_name example.com;
        charset     utf-8;

        # Django admin media.
        location /media/admin/ {
          alias lib/python2.6/site-packages/django/contrib/admin/media/;
        }
        # Your project's static media.
        location /media/ {
          alias PROJECT_ROOT/media/;
        }

        # Finally, send all non-media requests to the Django server.
       location /ai {
          uwsgi_pass  127.0.0.1:8807;
          include     uwsgi_params;
        }
      }

and the $VIRTUVAL_ENV/ironjob/ai/index.py file that contains the callable application:

    import os
    import sys
    from webob import Response
    from cgi import parse_qs, escape
    import urllib

    from ironMainManager import MainManager

    os.environ['PYTHONJ_EGG_CACHE'] = '$VIRTUAL_ENV/bin/.python-egg'

    def application(environ , start_response):
        mManager = MainManager()
        parameters = parse_qs(environ.get('QUERY_STRING', ''))
        returnval ="<Root></Root>"

        if 'api' in parameters:
            api = parameters['api'][0]
            if 'platform' in parameters:
                    platform = parameters['platform'][0]
                    if platform == 'browser':
                           api = urllib.unquote(str(parameters['api'][0]))
            print api
            returnval = mManager.process(api)
            output = 'success'
        else:
            output = 'error'

        res = Response()
        res.content_type = 'text/plain'
        res.body=str(returnval)
        return res(environ, start_response)
