What part of the Java platform do servlets and JSP belong to?
The servlet and JSP APIs are a standard extension to the core Java API and runtime system. Their package names are prefixed javax to indicate they are standard extensions, but that means that they rely upon a code implementation provided by a specific vendor. For example, the Apache Tomcat project supplies its own implementation of the servlet and JSP API that is integrated with the servlet container. Developers must compile their code using the vendor’s servlet package implementation by including it in the compiler’s classpath. The servlet container includes the same package classes in its runtime system and feeds concrete instances of the servlet interface types to the servlet’s lifecycle methods.
