JavaServer Pages (JSP) is a technology used to develop dynamic web applications by embedding Java code directly into HTML pages. It allows developers to create web pages with interactive content and logic, separating the presentation layer from business logic. JSP files have a “.jsp” extension and are processed by a servlet container like Apache Tomcat. The code within JSP is executed on the server, and the resulting output is sent to the client’s browser as standard HTML. JSP supports features such as tag libraries, expressions, and custom tags, making it a powerful tool for building scalable web applications.
