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.

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.
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.
Java Web Start allowed the launching of unmodified applet code, which then ran in a separate window (not inside the invoking browser). A Java Servlet is sometimes informally compared to be "like" a server-side applet, but it is different in its language, functions, and in each of the characteristics described here about applets.
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.

Jakarta Faces, formerly Jakarta Server Faces and JavaServer Faces (JSF) is a Java specification for building component-based user interfaces for web applications. [2] It was formalized as a standard through the Java Community Process as part of the Java Platform, Enterprise Edition.
The actual View can be written in different view technologies, like JSP, free marker template, velocity template etc. An XML configuration file is used to specify the "Page Navigation", i.e. the flow of the request to the appropriate Controller, and which View to display based on the outcome of the Controller.
