Class ContextListener

java.lang.Object
  com.google.inject.servlet.GuiceServletContextListener
      net.sf.jguard.jee.listeners.ContextListener

All Implemented Interfaces:

EventListener, javax.servlet.ServletContextListener

public abstract class ContextListener
extends com.google.inject.servlet.GuiceServletContextListener

initialize authentication and authorization engines in jGuard. it needs to be be declared in the web.xml file, to be called by the servlet engine lifecycle BEFORE servlet filters and servlets. it permits to initialize Authentication and Authorization only once, for potentially multiple server side technologies used in cunjunction.
