Seems like your authenticator cannot be found.

You have probably not read the documentation and followed it correctly.
Ensure that in components.xml you have

xmlns:authentication="http://jboss.com/products/seam/authentication"
<security:identity authenticate-method="#{authenticator.authenticate}"/>

And use a normal javabean as authenticator.

@Name("authenticator")
public class Authenticator {

public boolean authenticate() {
...
}
}
