Not able to inject ResouceResolverFactory

[#1]

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:

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

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/c...

In /system/console/componenets

What i observed that:-

ccom.adobe.ClassName  and its status is Satisfied

[#5]

com.adobe.connect.osgi.service.connect-osgi-service:connectSession=connect

where connect is serviceuser.

[#6]

Post a Screen shot of your OSGI SLING MAPPING - i suspect issue is there. 

[#7]

What do you see here? 

/system/console/components

There should be a reason why the dependency can't be injected

[#8]

Yes,I tried to debug and resourceResolverFactory is null throw java.lang.NullPointerException: null

[#9]

        Have you tried to debug? Are you sure that resourceResolverFactory is null? I suggest you to debug or insert a log in order to be sure that this is not related to wrong configuration of user mapper or user amendement service..

[#10]

Actually,

At this line, 

1. rr = resourceFactory.getServiceResourceResolver(paramMap);

It throws java.lang.NullPointerException.

I think resourceFactory variable is not injected in osgi bundles..

[#11]

But what is the issue you are having? That is not clear to me now.

[#12]

Yes, I have configured the user mapping configuration in system console. 

In osgi bundles, wherever the .loginAdministrstive(null) is called , i have replaced by below written codes:-

1. @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){ } }

[#13]

        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?

[#14]

This looks a non-related error

[#15]

        Thank you for clarification.

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.

[#18]

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

[#19]

Do you see anything related in the error.log?
