Hi Leonado,

               You have not mentioned context info or atleast stacktrace.Please provide perfect answer. Any how please find the causes of null pointer exception.

•       You are trying to acess the reference  without assigning an object(created object).

eg: String s = null;

         s.length();// null pointer exception.

I think u might know this concepts. For your scenario provide detail steps.
