to run fastagi you will need to startup up a thread during application 
context initialization to act as the fast agi server.

To do this implement a /*/ServletContextListener/ 
<http://java.sun.com/products/servlet/2.3/javadoc/javax/servlet/ServletContextListener.html> 
and during the 'contextInitialized' method call create a the thread 
which will run your fastagi server.

Note: the ServletContextListener needs to be configured in your web.xml.
