1. This example mainly tells us how to use JSP actions in JSP code, such as <jsp:forward >
2. This example requires four files: login. Jsp,test. Jsp,ok.htm,no.htm
3. First 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><br>
password<input type=password name=password>
<br><br>
<input type=submit value="确定">
</form>
</center>
</HTML>
4. test.JSP代码如下：
<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.htm and no.htm are very simple, casually written:
<HTML>ok</HTML>
<HTML>no</HTML>
6. The final configuration, very simple:
Put login. Jsp,test. Jsp,ok.htm,no.htm placed in the public_html of Java EE, you do not need to start the Java EE deployer, this is a simple way
7. The effect is when you enter the user name is ABC, the page will automatically jump to the ok.htm page, otherwise jump to the no.htm page
