I am using jboss-seam-2.2.0.GA, authenticator class to authenticate the login process. When I enter the username and password and submit the page, I am getting following error message in my logs:

application E javax.el.PropertyNotFoundException: /login.xhtml @27,76 action="#{authenticator.login()}": Target Unreachable, identifier 'authenticator' resolved to null
 javax.faces.el.EvaluationException: javax.el.PropertyNotFoundException: /login.xhtml @27,76 action="#{authenticator.login()}": Target Unreachable, identifier 'authenticator' resolved to null

Your Authenticator class appears to be implemented correctly. I'd search further up in your logs and find out why it isn't being created.

Also, I'd suggest posting the relevant section from components.xml. Should be something like:

<security:identity authenticate-method="#{authenticator.login}"/>
