1. This instance mainly tells us how to use JSP actions in JSP code, for example, <JSP: Forward>
2. This instance requires four files: login.jsp,test.jsp, OK .htm,no.htm
3. First, let's take a look at login. jsp.
<HTML>
<Center>
<Form method = get action = "http: // 127.0.0.1: 8000/test. jsp">
Username <input type = text name = username>
<Br>
Password <input type = password name = PASSWORD>
<Br>
<Input type = submit value = "OK">
</Form>
</Center>
</Html>
4. The test. JSP code is as follows:
<HTML>
<%
String username = request. getparameter ("username ");
If (username. Trim (). Equals ("ABC "))
{%>
<JSP: Forward page = "OK .html"/>
<%}
Else
{%>
<JSP: Forward page = "no.html"/>
<%}
%>
</Html>
5. OK .htmand no.htm are very simple and can be written at will:
<HTML> OK
<HTML> NO
6. The configuration is very simple:
Put login.jsp,test.jsp, OK .htm,no.htm IN THE public_html of J2EE. You do not need to start the J2EE deployer. This is a simple method.
7. When the user name is ABC, the page is automatically redirected to the OK .htmpage. If the user name is ABC, the page is redirected to the No. HTM page.
