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:

    Are you sure you have to reference for the resolverFactory?

    If there is no     @Reference
        private ResourceResolverFactory resolverFactory;

     

    Then there is no access to the class ResourceResolverFactory.

    All the examples also use     @Reference
        private ResourceResolverFactory resolverFactory;

    This works in AEM 6 - here is the output in the AEM 6 Touch UI:

    Hi Clive,

    It would be great if you can put down the solution which you did to resolve this issue.

    I think I may have written a response incorrectly.

     

    No solution yet. 

     

    I am going to update to SP1 in AEM and see if that resolves it. 

     

    If I find a solution I will post it on here.

     

     

    Apologies

    Hi Clive,

    I am facing a similar issue. This line throws a NullPointerException:

    ResourceResolver resourceResolver =resolverFactory.getAdministrativeResourceResolver(null);

    Any solution yet?

    Thanks

    "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.
