Advanced Jakarta Servlets: Servlet Context Listeners
Servlet context listeners are your secret weapon for managing application-wide resources. They spring into action when the servlet context is created or destroyed, making them perfect for tasks like initializing shared data, establishing database connections, or loading configuration settings as your application starts.In this course, you’ll learn all about event listeners and attribute monitoring in servlets. you’ll discover how listeners respond to changes in the servlet lifecycle and application context, and explore the various types of event and attribute listeners. you’ll also gain insight on how to build and register a ServletContextListener to manage key tasks during application startup and shutdown.Next, you’ll learn how to configure servlet listeners using annotations, and use context parameters to disable specific servlet context listeners. Finally, you’ll learn how to monitor attribute events and ensure your apps react appropriately when shared data is used and changed across your application.
