Class not found exception (java.lang.ClassNotFoundException: jakarta.activation.DataHandler)

Question

I am doing a project for interview. I am working with Spring Boot and mail API. When I try to run the application, it throws class not found exception (java.lang.ClassNotFoundException: jakarta.activation.DataHandler).

How can I handle this exception

This is my code

package com.student.service;

import java.util.Properties;

import org.springframework.stereotype.Service;

import jakarta.mail.*;
import jakarta.mail.Authenticator;
import jakarta.mail.Message;
import jakarta.mail.PasswordAuthentication;
import jakarta.mail.Session;
import jakarta.mail.Transport;
import jakarta.mail.internet.InternetAddress;
import jakarta.mail.internet.MimeMessage;

@Service
public class EmailService {
    public boolean sendEmail(String subject, String message, String to) {
        boolean f = false;
         String from = "sandip@gmail.com";
         String host = "smtp.gmail.com";
         Properties properties = System.getProperties();
         System.out.println("Properties: " + properties);
         properties.put("mail.smtp.host", host);
         properties.put("mail.smtp.port","465");
         properties.put("mail.smtp.ssl.enable", "true");
         properties.put("mail.smtp.auth", "true");
         
         //step 1: to get the session object
         Session session = Session.getInstance(properties, new Authenticator() {

            @Override
            protected PasswordAuthentication getPasswordAuthentication() {
                return new PasswordAuthentication("sandip@gmail.com", "123");
            }
        });
         session.setDebug(true);
         
         //step 2: compose the message [text, multi media]
         MimeMessage m = new MimeMessage(session);
         try {
             //from email
             m.setFrom(from);
             
             //adding recipient to message
             m.addRecipient(Message.RecipientType.TO, new InternetAddress(to));
             
             //adding subject to message
             m.setSubject(subject);
             
             //adding text to message
             m.setText(message);
             
             //step 3: send the message using Transport class
             Transport.send(m);
             
             System.out.println("Sent Success..............");
             f = true;
            
        } catch (Exception e) {
            e.printStackTrace();
        }
         return f;
    }
}

This is the error
