Jakarta EE (formerly Java EE) is the standard enterprise Java platform, providing a comprehensive set of specifications for building scalable, multi-tier server-side applications. It covers the full stack from web tier components like Servlets and JSP to enterprise services like CDI and EJB, along with robust support for RESTful and SOAP web services.

This series covers core Jakarta EE APIs in practical application, organized by concern: from setting up and deploying applications on Jakarta EE servers, through building the web tier with servlets and view technologies, designing service layers with JAX-RS and JAX-WS, enforcing contracts with Bean Validation, and managing enterprise components with CDI and EJB.
