A Jakarta Servlet, formerly Java Servlet is a Java software component that extends the capabilities of a server.Although servlets can respond to many types of requests, they most commonly implement web containers for hosting web applications on web servers and thus qualify as a server-side servlet web API.
The Servlet API is the foundation of almost all Java Web View technologies. Servlet provides the basic mechanism for writing Java classes for web applications. Servlets can respond to HTTP requests, create cookies and maintain sessions.
The Spring Framework is an application framework and inversion of control container for the Java platform. [2] The framework's core features can be used by any Java application, but there are extensions for building web applications on top of the Java EE (Enterprise Edition) platform.

OSGi Bundle Life-Cycle. A Life Cycle layer adds bundles that can be dynamically installed, started, stopped, updated and uninstalled. Bundles rely on the module layer for class loading but add an API to manage the modules in run time. The life cycle layer introduces dynamics that are normally not part of an application.
