<%@ page language=java import=java.util.* pageEncoding=utf-8%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+://+request.getServerName()+:+request.getServerPort()+path+/;
%>

> <% String User=request.getParameter(User); String Password=request.getParameter(Password); if(User.equals(Admin) && Password.equals(Admin)){%> <%} else { %> <%} %>
3.errorPage.jsp; 注意isErrorPage=TRUE；

 

 

<%@ page language=java import=java.util.* pageEncoding=UTF-8 isErrorPage=true%>
