still problems with null pointer exception in validator.validate..

["SATISH.T" <sa...@wipro.com>]

Hi 
Was just trying to implement a similar example as given in
struts-validator package 
I get the following problem when I try to call myForm.validate method
where myform extends from ValidatorForm.
I have configured the validatorServlet to load my validation.xml and
validator-rules.xml  in my applications web.xml  properly.
Can some one tell me why such an exception occurs.
Regards
Satish
