need help with jsp email

I have the following:

<%@ page import="java.util.*" %>
<%@ page import="javax.mail.*" %>
<%@ page import="javax.mail.Session.*" %>
<%@ page import="javax.mail.internet.MimeMessage.*" %>
:
            try {
                Properties props = new Properties();
                props.put("mail.smtp.host", "127.0.0.1");
                Session s = Session.getInstance(props);
                MimeMessage message = new MimeMessage(s);
                InternetAddress from = new InternetAddress("mark@ohprs.org");
                message.setFrom(from);
                InternetAddress to = new InternetAddress(homeEmail);
                message.addRecipient(Message.RecipientType.TO, to);
                message.setSubject("OHPRS Pension Website");
                message.setText("Your new password is " + newPw);
                Transport.send(message);
            }
 
I get the errors:

Session cannot be resolved to a type
An error occurred at line: 204 in the jsp file: /forgotPassword.jsp
Session cannot be resolved
An error occurred at line: 204 in the jsp file: /forgotPassword.jsp

Any idea what is wrong? I copied this code basically verbatim from another, successful, EE posting. I am using Linux, tomcat 6.0

I do not appear to have mail.jar or activation.jar on this computer. Does that mean I have to install them?

download them, you can get it by Java Mail API

ksivananth: I'm sure your solution is correct, so I will accept it as such. But, since email apparently doesn't acctually get shipped with Java and since I don't need it that much, I've decided to go with a system specific although encapsulated jsp function solution which I have include below.

Thanks -- I may get around to installing javamail one day when I'm bored!

/*  -----------------------------------------------------------------
    The Java email package is not included with the standard release.
    Rather than install it, we will use the system interface instead.
    This will need to be changed if this application is ever moved
    off Linux/Unix. See emailJava.txt for code to use Java email.
    The email installation download is in javamail-1_4_1.zip
    somewhere on this disk.
