Selenium POM java.lang.NullPointerException

Question

I am getting "java.lang.NullPointerException" when I am trying to execute my test case based on POM. The class BrowserFactory lets me choose a browser, the class Flipkart_Login based on POM stores all the element of that particular page and has a method for Valid_Login() and finally Test_Flipkart_Login class - calls the Valid_Login() method for executon but when I try to execute this class, I get java.lang.NullPointerException.

Kindly advise!

You have initialized Properties pro in the constructor of the COnfigDataProider but you are using a static call to getURL method from your test class. Thus pro will be null and not initialized. Remove static call and use the constructor or make pro to static and initialize in static block.
