automating multiple digital asset upload

[vishalp01051978]

We are using AEM 6.1. 

We tried the solution based on https://helpx.adobe.com/experience-manager/using/multiple-digital-assets.html

We customized HandleFile.java a bit (just one line). It is attached here. HandleFile.java has a method writetoClintLib and it fails with NullPointerException at ResourceResolver resourceResolver = resolverFactory.getAdministrativeResourceResolver(null);

Seems like injection for ResourceResolverFactory is not working, but not sure why.

As shown at the start of the article - this article was tested on CQ 5.5, 5.6, and 6.

I will test on 6.1 on tues and see if it works. I suspect that on 6.1 - this line is not working properly:

 //Inject a ResourceResolver
 ResourceResolver resourceResolver = resolverFactory.getAdministrativeResourceResolver(null);

Best practice in 6.1 is to use an AEM system user and use code like: 

Map<String, Object> param = new HashMap<String, Object>();
        param.put(ResourceResolverFactory.SUBSERVICE, "jqom");
        ResourceResolver resolver = null;
          
        try {
                     
            //Invoke the getServiceResourceResolver method to create a Session instance
            resolver = resolverFactory.getServiceResourceResolver(param);

To learn how to create a system user and use it to create a ResourceResolver - see this AEM community article:

Adding to what Scott has mentioned, it is not good practice to use getAdministrativeResourceResolver method. It has been depricated from ResourceResolverFactory.

Please have a look at the link, it will answer all your questions :-

Link:- http://www.accunitysoft.com/resourceresolver-object-in-aem6-16-0-sling-services/

//Use getServiceResourceResolver()

Here step by step everythig is mentioned, how to use it. And how to use it in AEM 6 and AEM 6.1.

I hope this would help you.

I tried creating system user and tried using getServiceResourceResolver instead of getAdministrativeResourceResolver, still it fails at same place with NullPointerException. Attached is the updated code.

Also attaching my version of client (simple java program) if you have trouble running swing client. It reads all the images in particular directory and try to upload them, as we have requirement to upload all the files in particular directory.

Were you able to try it?

I tested the binary code available on the documentation page with AEM 6.1 instance and it worked fine for me. This is what I did- 

• Installed the bundle jar(in DAMSlingServlet.zip) file using felix/console and activated the bundle. 
• Clicked the bundle name in felix and checked the following

     

Used Services

Service #18 of type(s) [org.osgi.service.log.LogService] Service #412 of type(s) [org.apache.sling.api.resource.ResourceResolverFactory]

• Opened URL - http://localhost:4502/system/console/slingauth and checked the servlet path is shown with no authentication required-       

  /bin/upmanydamfiles

  No

  Service 3609

• Fired a POST request using curl to upload a file-

• curl  -F "image=@/home/test.jpg" -F "@imageTitle=/content/dam/test.jpg" http://localhost:4502/bin/upmanydamfiles

Validated the JPEG file in DAM and there were no exceptions.
