How to control which button is processed in JSP.

How to control which button is processed in JSP.

I have a html page called "formftplogoff.htm"
The form has two buttons:
[Yes] and [No]
Here is the simple form

If the Yes button is executted it goes to a JSP page "processftplogoff.jsp" and the logging of process is executed. How can I control the second operation When "no" is pressed. If no is presses than the user is taken to page called "preferences.jsp". How can I do this?

The book I am using shows forms with "submit" button so basically one buton action. Please help.



<html>
<head>
 <title> FTP Log off </title>
<body>

<p>Do you wish to log off from ftp server?</p>
<FORM ACTION="processftplogoff.jsp" METHOD="get">
 <input type="button" value="Yes" name="b1">
 <input type="button" value="No" name="b2">
</form>
</body>
</html>

Use two form tags instead of one like this
Also use input type=submit
I hope this should work

<html>
<head>
<title>
FTP Log off
</title>
<body>
<p>Do you wish to log off from ftp server?</p>
<FORM ACTION="processftplogoff.jsp" METHOD="get">
<input type="submit" value="Yes" name="b1">
</FORM>

<FORM ACTION="preferences.jsp" METHOD="get">
<input type="submit" value="No" name="b2">
</form>
</body>
</html>

Into HTML:
......
<form action="processftplogoff.jsp" method="GET">
<input type="Submit" name="okbutton" value=" OK " >
<input type="Submit" name="cancelbutton" value=" Cancel ">
......

Into jsp:

<%

String action=request.getParameter("Submit");
...
System.out.println("You pressed "+action+" button");
if ( action.equals("okbutton") ) {
// OK button
} else if ( ation.equals("cancelbutton") ) {
// CANCEL button
}

%>
