RESTful Web Services with JAX-RS and Jakarta EE

Modern enterprise applications demand scalable, secure, and well-structured APIs to connect systems and power front-end applications. JAX-RS remains the standard Java specification for building these robust RESTful web services. This text-based course guides you from the fundamental concepts of HTTP and REST to writing production-grade JAX-RS web services. You will learn how to structure your enterprise Java applications, handle errors gracefully, and process requests efficiently. What you'll learn: Understand REST architecture principles and map HTTP methods to JAX-RS resource classes; Implement robust exception handling using native exception mappers to return clean, standardized API responses; Apply JAX-RS filters and interceptors to manage cross-cutting concerns like logging and authentication; Bind and validate incoming payload data using modern JSON-B and Bean Validation standards; Practice designing clean, maintainable enterprise architectures that separate business logic from API endpoints. You will start with key terminology, basic HTTP concepts, and foundational JAX-RS annotations. From there, you will progress through written explanations and code snippets covering data serialization, request filtering, and enterprise design patterns. This course is designed for Java developers looking to build web services, with no prior API development experience required.
