JSP
JSP (JavaServer Pages) is a server-side technology used to create dynamic web content by embedding Java code within HTML pages. It allows developers to build web applications that generate HTML, XML, or other document types in response to client requests, typically running on a Java servlet container like Apache Tomcat. JSP pages are compiled into servlets at runtime, enabling the execution of Java logic to produce customized output for users.
Developers should learn JSP when building enterprise-level web applications in Java, especially for legacy systems or projects requiring integration with Java EE (Enterprise Edition) ecosystems. It is useful for scenarios where dynamic content generation is needed, such as e-commerce sites, content management systems, or applications that rely on Java-based backend logic and databases. However, for modern development, it is often supplemented or replaced by more advanced frameworks due to its limitations in separation of concerns.
