80. Sling Servlet in AEM.
Sling Servlet in AEM. If you have ever worked with java web application, you might have worked with servlets before. Servlets handle the request coming into a java based web application.
Sling appliation use scripts/servlets to process http request in a restful way. Sling is resource oriented which maps into a JCR nodes. With sling a request url is first resolved to a resource and then based on the resource, it selects the actual servlet/script to handle request.
Requests are handled by either script/Servlet in AEM. We can access servlets in two ways.
1. path
2. resourcepath.

Servlets are registered as osgi service/bundle. Defining the servlet using scr annotations has been deprecated from aem 6.2 that's why I have used osgi declarative service annotations in this video.
