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.
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.
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.

A second way is the developments of CFX tags using Java or C++. CFX tags are prefixed with "cfx_", for example "cfx_imap". Tags are added to the ColdFusion runtime environment using the ColdFusion administrator, where JAR or DLL files are registered as custom tags. Finally, ColdFusion supports JSP tag libraries from the JSP 2.0 language ...
The degree of logic permitted in the view varies among different implementations. At one extreme, the view is entirely passive, forwarding all interaction operations to the presenter. In this formulation, when a user triggers an event method of the view, it does nothing but invoke a method of the presenter that has no parameters and no return ...
