Class ShieldingListener

java.lang.Object
  org.apache.cocoon.maven.deployer.servlet.ShieldingListener

All Implemented Interfaces:

EventListener, javax.servlet.http.HttpSessionActivationListener, javax.servlet.http.HttpSessionAttributeListener, javax.servlet.http.HttpSessionBindingListener, javax.servlet.http.HttpSessionListener, javax.servlet.ServletContextAttributeListener, javax.servlet.ServletContextListener, javax.servlet.ServletRequestListener

public class ShieldingListener
extends Object
implements javax.servlet.http.HttpSessionListener, javax.servlet.ServletContextListener, javax.servlet.http.HttpSessionActivationListener, javax.servlet.http.HttpSessionAttributeListener, javax.servlet.http.HttpSessionBindingListener, javax.servlet.ServletContextAttributeListener, javax.servlet.ServletRequestListener

This listener can be used as a wrapper around "real" listeners to support the shielded class loader.
