JSONFactoryImpl not able to inject

[6年前 に Rajesh Chaurasia によって更新されました。]

Hi

I wanted to know how to inject JSONFactoryImpl in below way as I am unable to get access to JSONFactoryImpl in my maven project.Wjat dependency will give me access to it in Liferay 7 setup

JSONFactoryUtil jsonFactoryUtil = new JSONFactoryUtil();
 jsonFactoryUtil.setJSONFactory(new JSONFactoryImpl());

There's no need to set the impl. JSONFactoryUtil already uses JSONFactoryImpl by default. To use JSONFactoryUtil, just call one of the static methods.

I am getting the below NPE exception

java.lang.NullPointerException
