using getAdministrativeResourceResolver(null) in AEM 6

[Clive_Stewart]

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

[Feike_Visser1]

Are you sure you have to reference for the resolverFactory?

[Clive_Stewart]

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.

Thank you for the offer. What time tomorrow (GMT) would suit you and how would we conduct communication?

Hi Clive,

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

[Clive_Stewart]

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.

I'm facing the similar issue . Getting "java.lang.NullPointerException: null" for getServiceResourceResolver(param); Any Help?

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

Scott's Digital Community: Querying Adobe Experience Manager 6 data using the Sling getServiceResour...

[keerthisujeethraj]

I tried complete video step by step But still facing the issue. Its showing ResourceResolverFactory is Null.

[keerthisujeethraj]

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

[smacdonald2008]

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

[keerthisujeethraj]

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.
