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 .
The compiled pages, as well as any dependent Java libraries, contain Java bytecode rather than machine code. Like any other .jar or Java program, code must be executed within a Java virtual machine (JVM) that interacts with the server's host operating system to provide an abstract, platform-neutral environment.
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.

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.
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 ...
