Not able to inject ResouceResolverFactory

Hi,

Not able to inject resouceresolverfactory in following code.

I created an interface

public interface WriteService{

    public void getSession();

{

And a class which implemented an interface

@Component(immediate=true) @Service(value = WriteSerive.class) public class WriteServiceImp  implements WriteService { @Reference private ResourceResolverFactory resourceFactory; @Override public void getSession(){ try{ Map<String,Object> paramMap = new HashMap<String,Object>(); paramMap.put(ResourceResolverFactory.SUBSERVICE, "connectSession"); ResourceResolver rr = null; rr = resourceFactory.getServiceResourceResolver(paramMap); Sessionsession = rr.adaptTo(Session.class); } catch(Exception e){ } }

 

Any Suggestion?

Thanks in advance

Watch the video here - we do a step by step of everything you need:

Scott's Digital Community: Querying Adobe Experience Manager 6 data using the Sling getServiceResourceResolver method

You need to reference the system user and make sure you specify the symbolic bundle name as mentioned in the video

        It seems that you are trying to use a system user to retrive you resource resolver.. have you configured the user mapping configuration in system console? And also.. this is a service where you reference it? Inside a model?

This looks a non-related error

The way you get the resourceResolver is fine, however you must close it. The golden rule is "you create, you close".

Normally you can do this in a finally{} clause, or if you use 6.2 or above you can benefit from the AutoCloseable implementation.

Example here: https://github.com/heervisscher/htl-examples/blob/master/core/src/main/java/com/adobe/examples/htl/core/service/AutoCloseableService.java

Hi Feike, I am using the same way to get resource resolver in my code. If this way of getting resource resolver is not advised, would you please suggest any other way to get resource resolver with admin rights.

Also do realize that this code creates hanging sessions that you want to avoid
