what exactly you want?
code in java / JSP?

if you hage got the code you have to specify ur SMTP server IP in it so as to send the mail.
==========================================================
Properties props = System.getProperties();

// Puts the SMTP server name to properties object
props.put("mail.smtp.host", smtp);
===========================================================

here is the link to java mail APIs to know more abt sending mail in java

Actually my code is
import java.util.*;
import javax.mail.*;
import javax.mail.internet.*;
import javax.activation.*;

// Send a simple, single part, text/plain e-mail
public class TestEmail {

public static void main(String[] args) {

// SUBSTITUTE YOUR EMAIL ADDRESSES HERE!!!
String to = "[e-mail]";
String from = "[e-mail]";
// SUBSTITUTE YOUR ISP'S MAIL SERVER HERE!!!
String host = "mail.yahoo.com";

// Create properties, get Session
Properties props = new Properties();

// If using static Transport.send(),
// need to specify which host to send it to
props.put("mail.smtp.host", host);
// To see what is going on behind the scene
props.put("mail.debug", "true");
Session session = Session.getInstance(props);

try {
// Instantiatee a message
Message msg = new MimeMessage(session);

//Set message attributes
msg.setFrom(new InternetAddress(from));
InternetAddress[] address = {new InternetAddress(to)};
msg.setRecipients(Message.RecipientType.TO, address);
msg.setSubject("Test E-Mail through Java");
msg.setSentDate(new Date());

// Set message content
msg.setText("This is a test of sending a " +
"plain text e-mail through Java.\n" +
"Here is line 2.");

//Send the message
Transport.send(msg);
}
catch (MessagingException mex) {
// Prints all nested (chained) exceptions as well
mex.printStackTrace();
}
}
}//End of class

here what is the isp's server(what is host name)?

It means you have to give Java Mail the address of the SMTP server it can use to send emails. So you need to get in touch with whoever administers the SMTP server you want to use and find out its DNS name or IP address.
