Implement the Serviceable interface. It forces you to implement the
service() method, where you get a ServiceManager instance passed. You
can store this in an instance var:
Public class MyAuthenticator implements Authenticator, Serviceable {
Private ServiceManager manager;
...
public void service(ServiceManager manager) throws ServiceException {
this.manager = manager;
}
}
Between instantiation of your authenticator, and calling one of the
Authenticator's interface methods, the "Cocoon system" will call the
service() method. Take a look at the
org.apache.cocoon.webapps.authentication.components.PipelineAuthenticato
r class for example.
