OSGi Basics
Your first guided steps into the OSGi world. Learn what OSGi is about and build your first Declarative Services.
If you don't have experience with OSGi yet, but are about to develop on Liferay DXP or customize it, this is the lesson for you.
This lesson is deliberately short, introducing the basic vocabulary and tools of OSGi so that you have just enough knowledge to start using OSGi in the context of Liferay. We dive more into OSGi details and background during the Back-End Development course.
