Package org.eclnt.jsfserver.util

Class CCInitializeServlets

java.lang.Object

org.eclnt.jsfserver.util.CCInitializeServlets

All Implemented Interfaces:

ICCServerConstants

public class CCInitializeServlets
extends Object
implements ICCServerConstants

Dynamic registration of filters, servlets and listeners.

The server environment of CaptainCasa used the definition via web.xml for quite a long time. Now new filters, servlets and listeners are directly registered in this class.

Advantage 1: whenever there is a change (e.g. new filter is added) then this change does not quire an update of then web.xml on application side.

Advantage 2: enviroments like Spring boot do not follow the web.xml based configuration. Calling the processing of this class within the startup of an e.g. Spring Boot container will properly start up the CaptainCasa runtime.

This class can be overridden by own implementations - and it is designed to be overridden! Your implementation class needs to be registered in system.xml:
<servletcontextconfiguration initializationclass="..." />
