By looking at the code and the stack trace, it seems that the User variable that is passed in login.Credential method is null.

Please try and initialize it with some value. Or for debugging purpose just pass some hardcode value in place of User

i hardcoded but still i get the null pointer exception, will there be any issue in locator – karthick Apr 06 '18 at 03:42
check that username element is initialized and also check that your driver instance is not null, by printing both these variables. – Prateeksha Chauhan Apr 06 '18 at 04:58
will there be any issue on pagefactory intialisation – karthick Apr 06 '18 at 05:03
yes it can be. If you are not passing your driver instance in action classes, or using driver without initialization, then it will result in null pointer – Prateeksha Chauhan Apr 06 '18 at 06:26
how to resolve it, can you please help me out – karthick Apr 06 '18 at 07:26
post you code please – Prateeksha Chauhan Apr 08 '18 at 04:55
