Sending Email using JSP

To send an email using JSP, you can use the JavaMail API. Here is an example of how to send an email in JSP:

1. First, you need to download the JavaMail API jar file and place it in your project's classpath.

2. Import the required classes at the beginning of your JSP page:

   <%@ page import="javax.mail.*, javax.mail.internet.*, java.util.*" %>

3. Create a JavaMail session by specifying the SMTP server and port number. You also need to provide the authentication details (username and password) for the SMTP server:

   <%
       String host = "smtp.gmail.com";
       String username = "your-email-address";
       String password = "your-email-password";
       String port = "587";
   
       Properties props = new Properties();
       props.put("mail.smtp.auth", "true");
       props.put("mail.smtp.starttls.enable", "true");
       props.put("mail.smtp.host", host);
       props.put("mail.smtp.port", port);
   
       // create a mail session with the given properties
       Session session = Session.getInstance(props, new Authenticator() {
           protected PasswordAuthentication getPasswordAuthentication() {
               return new PasswordAuthentication(username, password);
           }
       });
   %>

4. Create a new message and set its properties, such as the sender's and recipient's email addresses, subject, and content:

   <%
       String from = "your-email-address";
       String to = "recipient-email-address";
       String subject = "Email Subject";
       String body = "Email Body";
   
       // create a new message
       Message message = new MimeMessage(session);
       message.setFrom(new InternetAddress(from));
       message.setRecipient(Message.RecipientType.TO, new InternetAddress(to));
       message.setSubject(subject);
       message.setText(body);
   %>

5. Send the message using the Transport.send() method:

   <%
       // send the message
       Transport.send(message);
   %>

The complete code for sending an email using JSP is as follows:

<%@ page import="javax.mail.*, javax.mail.internet.*, java.util.*" %>

<%
    String host = "smtp.gmail.com";
    String username = "your-email-address";
    String password = "your-email-password";
    String port = "587";

    Properties props = new Properties();
    props.put("mail.smtp.auth", "true");
    props.put("mail.smtp.starttls.enable", "true");
    props.put("mail.smtp.host", host);
    props.put("mail.smtp.port", port);

    // create a mail session with the given properties
    Session session = Session.getInstance(props, new Authenticator() {
        protected PasswordAuthentication getPasswordAuthentication() {
            return new PasswordAuthentication(username, password);
        }
    });

    String from = "your-email-address";
    String to = "recipient-email-address";
    String subject = "Email Subject";
    String body = "Email Body";

    // create a new message
    Message message = new MimeMessage(session);
    message.setFrom(new InternetAddress(from));
    message.setRecipient(Message.RecipientType.TO, new InternetAddress(to));
    message.setSubject(subject);
    message.setText(body);

    // send the message
    Transport.send(message);
%>

<h1>Email Sent</h1>

Note: This example uses Gmail as the SMTP server, but you can use any other SMTP server by modifying the "host" and "port" properties accordingly.
