[jboss-user] [JBoss Seam] - Seam's Identity and Authenticator

[tonylmai]

Can someone tell me the correlation between Seam's Identity and Authenticator?

It is my understanding that we can declare/override the RuleBasedIdentity as followed:

@Name("org.jboss.seam.security.identity")
  | @Scope(ScopeType.SESSION)
  | @Intercept(InterceptionType.AFTER_RESTORE_VIEW)
  | public class MyIdentity extends RuleBasedIdentity {
  | ...	
  | 	@Override
  | 	public String login() {
  | 		super.login(); /* Ignore outcome from super */
  | 		
  | ...
  | 		return "nextPage";
  | 	}

And use it in our web page as followed:
<h:commandButton value="Login" action="#{identity.login}"/>
  | 

Then I also see code using Authenticator as followed:

component.xml
   <security:identity authenticate-method="#{authenticator.authenticate}" security-rules="#{securityRules}"/>
with
@Name("authenticator")
  | public class Authenticator {
  |     @In
  |     Identity identity;
  | 
  |     public boolean authenticate() {
  | ...
  |      	return true;
  |     }
  | 

Is there an implicit correlation between these two component? Or are they mutually exclusive? Is one better than the other? 

Thanks for your help.
