Subject: how to use set(get)Property
hi, I'm a new comer to Jsp, work on jswdk1.0.1. Here is a question about
java bean, hope any help.
Following are two jsp:
Login.jsp
<%@ page import="java.util.*, library.Map" %>
<jsp:useBean id = "mymap" scope = "session" class="library.Map" />
<jsp:setProperty name ="mymap" property="username" param ="username" />
...
<FORM NAME="Form1" METHOD="GET" ACTION="Library.jsp">
....
Library.jsp:
<%@ page import="java.util.*, library.Map" %>
....
<jsp:getProperty name ="mymap" property="username" />
when it runs , an exception will be thrown such as:
com.sun.jsp.JspException getProperty: Bean mymap not found.
if use
<%= mymap.getUsername() %>
it will say,
Undefined variable or class name : mymap
I don't know how to make it work. Any help will be appreciated,
especially an example.
Thanx.
