You should copy this directory to your document root. 
Do not forget to enable the wsgi/ directory to execute WSGI applications. 


The following structure worked for me:

/var/www/wsgi/webplugin_example.py 
/var/www/tmp/			     # chmod 777 
/var/www/webplugin_example.html
/var/www/jquery-1.4.2.min.js
/var/www/ete.js
/var/www/ete.css

My apache config para el sitio "default":


<VirtualHost *:80>
 ServerAdmin webmaster@localhost

 DocumentRoot /var/www
 <Directory />
        Options +FollowSymLinks
        AllowOverride None
 </Directory>

 ErrorLog /var/log/apache2/error.log

 # Possible values include: debug, info, notice, warn, error, crit,
 # alert, emerg.
 LogLevel warn

 CustomLog /var/log/apache2/access.log combined
