Accessing OOTB Service/Servlet from Sling Servlets

try this-

RequestDispatcher dispatcher = request.getRequestDispatcher("/bin/wcm/contentfinder/asset/view.json/content/dam", opts);

dispatcher.include(request, response);

Cool smacdonald2008, Is there any community article reference where service is being called from servlet through "path" but not by @Reference? and works in author environment seamlessly?

Creating custom Sling Servets in a valid approach. Most of the examples we have of Servlets - we use AJAX to invoke the servlet. BUt you can invoke it using supported HTTP methods.

The concerns I see with HTTP approach is authorization i.e., to access it on author environment.

Below is the requirement we are trying to fulfill - By OOTB, content finder images are loaded from /content/dam but the requirement is to filter this. We need to load the images only 2 folders with in /content/dam.

By analyzing the ootb code, we realized that we can read images only from one folder by modifying  /libs/wcm/extensions/contentfinder/images.js file.

We can update URL at "url": "/bin/wcm/contentfinder/asset/view.json/content/dam{/appspecfolder}" to the desired folder but we are unable to provide multiple folder paths here.

So our approach is to replace this service with a custom servlet and internally call the OOTB service twice and merge the results and use that to populate content finder.

Please let me know if there is a better way to solve this. Thanks in advance.

If you only know the path to a servlet - only possible way is to invoke it using HTTP.

smacdonald2008 Thanks for the reply but I will not be able to use @Reference because I know only the path by which we can access the service (/bin/wcm/contentfinder/asset/view.json/content/dam). There should be some way to access the service right?

To invoke another AEM Service from a Sling Servlet - you use @Reference.
