using getAdministrativeResourceResolver(null) in AEM 6

I am trying to use the following line of code from http://helpx.adobe.com/experience-manager/using/using-sling-apis.html

ResourceResolver resourceResolver =resolverFactory.getAdministrativeResourceResolver(null); //line 82

but I get java.lang.NullPointerException
at shoprite.holdings.impl.FetchStores.jcrStoresUptodate(FetchStores.java:82)

at shoprite.holdings.impl.FetchStores.<init>(FetchStores.java:66)

at shoprite.holdings.impl.StoreLocatorImpl.getStores(StoreLocatorImpl.java:26)

at shoprite.holdings.TestGetStores.main(TestGetStores.java:14)

I have tried to replace this with the following code from the blog "AEM6: ResourceResolver access in services" http://cqblog.inside-solutions.ch/category/cq5/.

Map<String, Object> param = new HashMap<String, Object>();
       param.put(ResourceResolverFactory.SUBSERVICE, "readService");
       ResourceResolver resolver = null;
       try {
           resolver = resolverFactory.getServiceResourceResolver(param);

However I get the following errors

The method getServiceResourceResolver(Map<String,Object>) is undefined for the type ResourceResolverFactory

and

SUBSERVICE cannot be resolved or is not a field.

From this I am assuming that the version of ResourceResolver I am using is not concurrent. I am definitely on version 6 of AEM. I am also not sure why the code example from AEM 5.6 ResourceResolver resourceResolver =resolverFactory.getAdministrativeResourceResolver(null); gives me a NullPointerException

See this video - it steps you though this - most likily cause is you did not configure Sling Mapping properly - see this article and video:

I used the symbolic bundle as showing in the video. I used general user instead of system user because its AEM 6.0. The issue is with the ResourceResolverFactory for me. its showing null. So I tried to get it through the Bundle Context and its resolved. Thank you.

In sling mapping, did you use symbolic bundle name? And you used a system user And granted the correct permissions?

I also change the dependency version of "org.apache.sling.api". Still no clue.

"The method getServiceResourceResolver(Map<String,Object>) is undefined for the type ResourceResolverFactory

and

SUBSERVICE cannot be resolved or is not a field."

This is due to your api version didn't contain SUBSERVICE field. Please upgrade your "org.apache.sling.api" version in the maven dependency and compile your code against it.

Hope this helps.
