重定向可以使用()方法。A、forwardpage= “login.jsp”/B、jsp:forwardpage= “login.jsp”/C、request.sendRedirect(“login.jsp”);D、response.sendRedirect(“login.jsp”);
JavaBean可以通过相关jsp动作指令进行调用。下面哪个不是JavaBean可以使用的jsp动作指令?()A、〈jsp:useBean〉B、〈jsp:setProperty〉C、〈jsp:getProperty〉D、〈jsp:setParameter〉
在J2EE中,在aa.jsp中有行代码: %% request.setAttribute("Co.","jb-aptech"); % 在bb.jsp中有行代码: % out.println((String)request.getAttribute("Co.")); % % 为了使得在bb.jsp中的如上代码可以显示“jb-aptech”,可以使用()方法。A、在aa.jsp中使用form method=post action="bb.jsp"把请求提交到bb.jsp B、在aa.jsp中使用jsp:forward file="bb.jsp" /把页面重定向到bb.jsp C、在aa.jsp中使用% response.sendRedirect("bb.jsp"); %把页面重定向到bb.jsp D、在aa.jsp中使用%@ include file="bb.jsp" %包含页面bb.jsp E、在aa.jsp中使用% config.getServletContext().getRequestDispatcher("/bb.jsp").forward(request,response); %把页面重定向到bb.jsp
在J2EE中,对于标记,描述正确的是()。 A、jsp:param是jsp:include、jsp:forward标记的子标记 B、如果aa.jsp有代码:jsp:forward page="next.jsp"jsp:param name="name" value="jb-aptech" //jsp:forward,则在next.jsp中可以使用request.getParameter("name");把属性name的值取出来 C、如果aa.jsp有代码:jsp:forward page="next.jsp"jsp:param name="name" value="jb-aptech" //jsp:forward,则在next.jsp中可以使用request.getAttribute("name");把属性name的值取出来 D、如果jsp:param标记不放在jsp:forward标记内,也就是不作为jsp:forward标记的子标记,则使用浏览器查看时会显示错误页面
