JSP (JavaServer Pages) is a technology that allows developers to create dynamic web pages based on HTML, XML, or other document types. JSP pages contain standard HTML markup along with embedded Java code, which is executed on the server to generate dynamic content. When a user requests a JSP page, the web server processes the page, executes the Java code, and sends the resulting HTML (or other document type) to the user's browser. This allows for the creation of interactive and data-driven web applications. JSP is part of the Java EE (Enterprise Edition) platform and relies on a servlet container (like Tomcat or Jetty) to execute the Java code. JSP pages are typically used for tasks such as displaying data from a database, handling user input, and generating personalized content. The Java code within a JSP page is typically used to access databases, perform calculations, and manipulate data before it is displayed to the user. JSP simplifies the development of dynamic web pages by allowing developers to embed Java code directly into HTML, rather than having to write separate Java servlets to generate the HTML. The JSP engine translates the JSP page into a servlet, compiles it, and executes it to generate the dynamic content.
