jakartaservlethttp

jakartaservlethttp refers to the HTTP-specific portion of the Jakarta Servlet API, the Java platform standard for building web applications within the Jakarta EE ecosystem. It defines how Java components handle HTTP requests and responses and how a web container dispatches those requests to servlet code. The API provides core abstractions such as HttpServlet, HttpServletRequest, HttpServletResponse, HttpSession, and related types like Cookie and ServletContext. Through these APIs, a servlet container translates incoming HTTP traffic into servlet method invocations and converts servlet responses back into HTTP responses, enabling dynamic web content, form handling, and programmatic control over HTTP features.

Historically, the HTTP portion originated in the javax.servlet.http package as part of the Java EE specification. With the transition from Java EE to Jakarta EE, the package namespace was renamed to jakarta.servlet.http, and Jakarta Servlet versions 5.x and later align with this change. The HTTP surface continues to support common servlet capabilities such as reading request parameters, managing sessions, handling cookies and headers, content negotiation, and asynchronous processing where supported.

Usage in practice typically involves developers extending HttpServlet and overriding methods like doGet and doPost, reading data from HttpServletRequest, and producing responses via HttpServletResponse. Developers may also employ filters to apply cross-cutting concerns (such as authentication or logging) to HTTP requests and responses, or use listeners and listeners to react to lifecycle events.

jakartaservlethttp is implemented by servlet containers such as Tomcat, Jetty, GlassFish/Payara, and WildFly, and it underpins deployment of web applications packaged as WAR files or modern equivalents within the Jakarta EE platform.
