The Servlet Container (like Apache Tomcat or Jetty) manages the servlet lifecycle, enabling smooth communication between web servers and browsers.</p> <p><strong>Why Jakarta Servlets Matter</strong><br> Despite Spring's dominance, servlets remain foundational to Java web development. Every request processed by Spring ultimately flows through a servlet. Understanding servlets helps developers better manage Java web applications.</p> <p><strong>Step 1: WAR File Deployment</strong><br> The Servlet Container deploys WAR files, extracting Java class files, scanning for annotations (@WebServlet, @WebFilter), and processing web.xml configurations. This prepares the application for initialization.</p> <p><strong>Step 2: Creating Servlet Context</strong><br> The Servlet Context is created, acting as a shared space where servlets, filters, and listeners interact. It stores global settings (e.g., database configurations) and is accessible throughout the application lifecycle.</p> <p><strong>Step 3: ServletContainerInitializer</strong><br> The container looks for ServletContainerInitializer in META-INF/services, bootstrapping custom logic like dynamically registering servlets or filters using the onStartup() method.</p> <p><strong>Step 4: Initializing Listeners, Filters, and Servlets</strong><br> The container initializes listeners, filters, and servlets. Filters intercept requests, and servlets are instantiated based on loadOnStartup configurations. Once initialized, the app is ready to handle requests.</p> <p>Stay tuned for the next article on Jakarta Servlet lifecycle during request processing!</p> <p><strong>Read the full article on Medium</strong> {<a href="https://medium.com/p/516dfa7496ff" rel="noopener noreferrer">https://medium.com/p/516dfa7496ff</a>} </p> webdev java programming backenddevelopment Vimukthi Jayasanka Sun, 16 Mar 2025 22:49:24 +0000 https://dev.to/vimukthi_jayasanka_816593/check-out-my-portfolio-1k83 https://dev.to/vimukthi_jayasanka_816593/check-out-my-portfolio-1k83 <p>In this post, I’ll share how I created my personal portfolio website using Vite for fast development, Firebase Hosting for seamless deployment, and integrated SEO best practices to ensure it’s discoverable and optimized for search engines.</p> webdev programming html frontend
