Hi Heinrich,

I suspect that you are importing the wrong Validator interface. Verify
that your import for Validator is:

javax.faces.validator.Validator

This class name is overloaded heavily and you may have selected the wrong
one by accident when organizing imports.

Just to be clear, I meant to check the interface in your
com.tutorial.validatePassword class.
