using getAdministrativeResourceResolver(null) in AEM 6

Avatar

Level 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.

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

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

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.
