I am trying to access resource like below with resource reoslver
try (ResourceResolver serviceResourceResolver = resourceResolverFactory.getServiceResourceResolver(null)) {

Resource resource = serviceResourceResolver.resolve(path);

}

i try to access resource.getPath() , getting the correct path, with the tag as

"NonExistingResource"

What will be the reason

Requesting you to please go through the video that I had shared earlier. There would be a lot of blogs also available.

 

This code isn't right

resourceResolverFactory.getServiceResourceResolver(null)) {

 

As service use mapping needs to exist against the bundle/Service with proper privileges.

  • Ideally one should create a Service and use it in the Listener.
    • Extract the required code in a common abstract class, which can be used by both Servlet and Service.
  • Do not execute heavy operations in listeners. Use Sling jobs instead

    Hi @yugansan 
    It's indeed like @aanchal-sikka is stating, the idea should be that your Servlet is using an underlying service which includes the logic that needs to be executed when calling your Servlet. If that is the case you could reuse the same service from your servlet into your ResourceChangeListener.

        You would need to user service-user to access resources. The Service itself doesn't have a session.
