如何让servlet输出内容到指定页

Answer 1

在servlet中将查询到的数据保存为session，然后再页面中显示即可；
servlet代码：
String userName = request.getParameter("username");
String passWord = request.getParameter("password");
if(userName != null && passWord != null){
HttpSession session = request.getSession();
session.setAttribute("uname", userName);
session.setAttribute("pword", passWord);
}
response.sendRedirect("index.jsp");
index.jsp显示页面：
XML/HTML code
<center><b>
<%
String uname = "";
String pword = "";
if(session != null){
uname = (String) session.getAttribute("uname");
pword = (String) session.getAttribute("pword");
if(uname != null && !uname.equals("") && pword != null && !pword.equals("")){
out.println("Input UserName: <font color='red'><b>"+ uname +"</b></font><br>");
out.println("Input PassWord: <font color='red'><b>"+ pword +"</b></font>");
}
}
%>
</b></center>
