selenium webdriver - Error when executing testng.xml using pagefactory -

i running 2 classes using testng.first class running second class failing error:

"org.testng.testngexception:can't invoke public void testscripts.newaccountcreation.accountcreation1(): either make static or add no-args constructor class"

if add non argument constructor getting null pointer exception.

i using pagefactory design test cases.

eclipse version:kepler

testng:6.9.9

chrome version: 57.0.2987.133

chrome driver: 2.27

any suggestions appreciated.

please find below code:

testng.xml

<?xml version="1.0" encoding="utf-8"?> <!doctype suite system "http://testng.org/testng-1.0.dtd"> <suite name="suite">   <test name="test">     <classes>       <class name="testscripts.login"/>       <class name="testscripts.newaccountcreation"/>     </classes>   </test> <!-- test --> </suite> <!-- suite --> 

newaccountcreation test class because contains test method(s) , because declare class test in testng.xml.

so, means testng must able create instance of class , that's why testng complaining.

you have 2 options:

1. using a factory explain testng how create test classes (best option imo)
2. using static shared driver instance (login#driver not yet static)

btw, organization of classes looks bit dirty , should rework them bit.
