Web specifications Jakarta Servlet: defines how to manage HTTP requests, in a synchronous or asynchronous way. It is low level and other Jakarta EE specifications rely on it; Jakarta WebSocket: API specification that defines a set of APIs to service WebSocket connections; Jakarta Faces: a technology for constructing user interfaces out of components; Jakarta Expression Language (EL) is a simple language originally designed to satisfy the specific needs of web application developers. It is used specifically in Jakarta Faces to bind components to (backing) beans and in Contexts and Dependency Injection to named beans, but can be used throughout the entire platform.
