Welcome to part 8, in this final part we will review Servlets & Filters in OSGI environment. More precisely we will look at only one case, Sling Servlets & Filters in AEM.
After reading this article, you should be able to
1. Create a Sling Servlet.
2. Create a Sling Filter.
3. Invoke a service from Servlet using reference.
4. Be able to use this Servlet Resolver Page.
Let me remind you that Sling is a REST based web framework build on top of OSGI.
Content-driven that means the framework first finds the content render then determines how to render it basing on the request.
It supports multiple programming languages for rendering scripts.
In this part we will concentrate on Sling Servlets & Filters. We will not discuss rendering pages & Components.
