The difference between servlets and JSP is that servlets typically embed HTML inside Java code, while JSPs embed Java code in HTML. In general, when using JSPs, embedding Java code in JSP is considered bad practice. [8] Instead, a better approach would be to move the back-end logic from the JSP to the Java code in the Servlet.

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.
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 ...

A web container (also known as a servlet container; [1] and compare "webcontainer" [2]) is the component of a web server that interacts with Jakarta Servlets.A web container is responsible for managing the lifecycle of servlets, mapping a URL to a particular servlet and ensuring that the URL requester has the correct access-rights.
According to the Java BluePrints, the business logic of an application resides in Enterprise Beans—a modular server component providing many features, including declarative transaction management, and improving application scalability. Web container: the web modules include Jakarta Servlets and Jakarta Server Pages (JSP).
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.
Eclipse Jetty is a Java web server and Java Servlet container. While web servers are usually associated with serving documents to people, Jetty is now often used for machine to machine communications, usually within larger software frameworks.
