JSP, Servlets, and JDBC: Build a Java Web App from Scratch

Transitioning from basic Java console programs to building real-world, interactive web applications can feel like a major leap. Understanding how the web tier connects to databases is the foundational step to becoming a capable Java web developer. This course guides you step-by-step through the process of building dynamic web applications. You will learn how to process user requests, manage application logic, and interact securely with databases using JavaServer Pages (JSP), Servlets, and Java Database Connectivity (JDBC). By applying the Model-View-Controller (MVC) design pattern, you will gain the skills to architect clean, maintainable web software from the ground up. What you'll learn: - Understand the core concepts of web architecture, including HTTP requests, responses, and servlet lifecycles. - Create dynamic user interfaces using JSP scripting elements, directives, and the Expression Language (EL). - Configure and manage database connections securely using JDBC and modern try-with-resources resource management. - Build a functional MVC web application featuring full CRUD (Create, Read, Update, Delete) capabilities. - Apply security best practices to protect your database queries against common vulnerabilities like SQL injection. - Organize your web projects using modern standards, including basic Maven configuration for dependency management. The course starts with essential web concepts and servlet fundamentals, moving step-by-step into UI generation with JSP, and finishes with connecting your application to a database for a fully functional project. Through clear written explanations and practical code walkthroughs, you will develop a solid foundation in classic Java web development. This course is designed for beginner Java programmers who want to transition to web development. No prior experience with web servers, HTML, or databases is required, though a basic understanding of core Java syntax is recommended.
