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 .
While the exact form of the MVC "Model" was never specified by the Model 2 design, a number of publications recommend a formalized layer to contain MVC Model code. The Java BluePrints, for example, originally recommended using EJBs to encapsulate the MVC Model. In a Model 2 application, requests from the client browser are passed to the ...
JSPs are translated into servlets at runtime, therefore JSP is a Servlet; each JSP servlet is cached and re-used until the original JSP is modified. [ 3 ] Jakarta Server Pages can be used independently or as the view component of a server-side model–view–controller design, normally with JavaBeans as the model and Java servlets (or a ...
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.
In software engineering, a WAR file (Web Application Resource [1] or Web application ARchive [2]) is a file used to distribute a collection of JAR-files, JavaServer Pages, Java Servlets, Java classes, XML files, tag libraries, static web pages (HTML and related files) and other resources that together constitute a web application.
This became Apache Tomcat version 3.0, the successor to JSWDK 2.1, and derailed further development of Apache JServ servlet engine and AJP towards support of Java servlet API version 2.1. [13] The current specification remains at version 1.3, [14] however there is a published extension proposal [15] as well as an archived experimental 1.4 ...

Pages directly interact with stateful Java components on the server. Components and their state are managed by the Wicket framework, freeing the application developer from having to use HttpSession directly to manage state. Does not require XML for configuration. Compared to JSPs, enforces a clear separation of HTML markup and Java code.
