Class ServiceInitializer

java.lang.Object

core.tut.pori.context.ServiceInitializer

All Implemented Interfaces:

java.util.EventListener, javax.servlet.ServletContextListener

public class ServiceInitializer
extends java.lang.Object
implements javax.servlet.ServletContextListener

Initializes and destroys the web application (service) context, and loads all other handlers during context initialization. This class can be used to retrieve instances of various handlers and classes instantiated by the handlers. One should never close the handlers or the instances returned by the handlers manually, as they are managed automatically. The handlers themselves are generally immutable and no modifications to the initialized contexts are possible.
