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:

If you want to have a connect session with me and we can figure out what is happening on your end, please let me know.

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.
