Life of a JSP file. A Jakarta Servlet, formerly Java Servlet is a Java software component that extends the capabilities of a server.Although servlets can respond to many types of requests, they most commonly implement web containers for hosting web applications on web servers and thus qualify as a server-side servlet web API.
Jakarta Server Pages (JSP; formerly JavaServer Pages) [1] is a collection of technologies that helps software developers create dynamically generated web pages based on HTML, XML, SOAP, or other document types. Released in 1999 by Sun Microsystems, [2] JSP is similar to PHP and ASP, but uses the Java programming language.
Apache Tomcat (called "Tomcat" for short) is a free and open-source implementation of the Jakarta Servlet, Jakarta Expression Language, and WebSocket technologies. It provides a "pure Java" HTTP web server environment in which Java code can also run. Thus it is a Java web application server, although not a full JEE application server.
The Servlet API is the foundation of almost all Java Web View technologies. Servlet provides the basic mechanism for writing Java classes for web applications. Servlets can respond to HTTP requests, create cookies and maintain sessions.
JAX-RS uses annotations, introduced in Java SE 5, to simplify the development and deployment of web service clients and endpoints. From version 1.1 on, JAX-RS is an official part of Java EE 6. A notable feature of being an official part of Java EE is that no configuration is necessary to start using JAX-RS.
JAX-WS uses annotations, introduced in Java SE 5, to simplify the development and deployment of web service clients and endpoints. It is part of the Java Web Services Development Pack . JAX-WS can be used in Java SE starting with version 6. [ 1 ]
The Jakarta Standard Tag Library (JSTL; formerly JavaServer Pages Standard Tag Library) is a component of the Java EE Web application development platform. It extends the JSP specification by adding a tag library of JSP tags for common tasks, such as XML data processing, conditional execution, database access, loops and internationalization.
The RS transmits the message as an HTTP request; The advantage of such a method is that it allows the Web service to be implemented at server-side as a Servlet or EJB container. Thus, Servlet or EJB applications are made available through Web services. Jakarta XML RPC (JAX-RPC) was removed from Jakarta EE 9. [3]
