Detailed Description

rwsf::ServletContextListener is an abstract base class for listeners that receive notifications when the Agent creates or destroys rwsf::ServletContext objects. To create a listener, derive from this class and override the functions that receive events, contextInitialized() and contextDestroyed(). To register a listener, include a deployment descriptor for the listener class in the configuration file of the context. For information on servlet contexts, please see the chapter on servlet concepts in the Servlet Development Guide. For example, the following line in web.xml registers an rwsf::ServletContextListener to a servlet context:

 <listener><listener-class>listeners.createTestListener</listener-class></listener>

Member Function Documentation

virtual void rwsf::ServletContextListener::contextDestroyed

(

const rwsf::ServletContextEvent &

event

)

[pure virtual]

The Agent calls this method when this rwsf::ServletContext goes out of scope. This method does any clean up the listener needs to perform.

virtual void rwsf::ServletContextListener::contextInitialized

(

const rwsf::ServletContextEvent &

event

)

[pure virtual]

This method gets called by the Agent when an rwsf::ServletContext object has just been created and rwsf::ServletContext is ready to start processing requests.
