Servlet怎麼使用jsp的內置對象

//out對象
		PrintWriter out=response.getWriter();
		//application對象
		ServletContext application=request.getServletContext();
		//session對象
		HttpSession session=request.getSession();
		//pageContext是jsp特有的，在Servlet無法獲取
		//config對象
		ServletConfig config=this.getServletConfig();
