JavaServer Pages (JSP) is a technology used for developing dynamic web pages by embedding Java code within HTML. JSP allows developers to create interactive content by utilizing special JSP tags, which enable the integration of Java logic directly into the web page structure. This technology simplifies the process of building web applications by separating the presentation layer from the business logic, enhancing maintainability and scalability. JSP pages are compiled into servlets, which are then executed on a server, allowing for efficient processing of user requests and dynamic content generation. Overall, JSP is a powerful tool for modern web development.
