protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { String imagePath = request.getRealPath("upload/image.jpg"); // Use the imagePath to process the uploaded image }
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { String jspPath = request.getRealPath("/WEB-INF/jsp/page.jsp"); // Forward the request to the JSP page RequestDispatcher dispatcher = request.getRequestDispatcher(jspPath); dispatcher.forward(request, response); }In this example, the real path of a JSP page named "page.jsp" is obtained from the HttpServletRequest object. The JSP page is assumed to be located in the "/WEB-INF/jsp" directory of the current web application. The path to this directory is obtained using the getRealPath() method and stored in the jspPath variable. The request is then forwarded to the JSP page using a RequestDispatcher object. The package library used in these examples is javax.servlet.http, which is part of the Java Servlet API. This library provides classes and interfaces for handling HTTP requests and responses in a web application.
