You got the two action mapping with the same name ( path="/Login" and
the class type ). You need to use one or the other.

This is because the Struts Config reads the first action mapping and
it takes precedence. The first action mapping says you want to use
the "DefaultForm" which is not a subclass of the ValidatorForm.
You should be able to work it with the Struts Validator,
if you delete the first action mapping.
