Sending Email through JavaMail API in Servlet, Here is the Example

To make a simple example of sending an email from the servlet. For this example we are going to create 3 files:

  • Index.html file for input
  • SendMail.java is a servlet file for handling the request and giving the response to the user. It uses the Send Method of the mailer class to send the email.
  • Mailer.java is a java class that contains send method to send the emails to the mentioned Recipient(receiver)


<form action="servlet/SendMail">  
To:<input type="text" name="to"/><br/>  
Subject:<input type="text" name="subject"><br/>  
Text:<textarea rows="10" cols="70" name="msg"></textarea><br/>  
<input type="submit" value="send"/>  


import java.io.IOException;  
import java.io.PrintWriter;  
import javax.servlet.ServletException;  
import javax.servlet.http.HttpServlet;  
import javax.servlet.http.HttpServletRequest;  
import javax.servlet.http.HttpServletResponse;  
public class SendMail extends HttpServlet {  
public void doGet(HttpServletRequest request,  
 HttpServletResponse response)  
    throws ServletException, IOException {  
    PrintWriter out = response.getWriter();  
    String to=request.getParameter("to");  
    String subject=request.getParameter("subject");  
    String msg=request.getParameter("msg");  
    Mailer.send(to, subject, msg);  
    out.print("message has been sent successfully");  


import java.util.Properties;  
import javax.mail.*;  
import javax.mail.internet.InternetAddress;  
import javax.mail.internet.MimeMessage;  
public class Mailer {  
public static void send(String to,String subject,String msg){  
final String user="sonoojaiswal@javatpoint.com";//change accordingly  
final String pass="xxxxx";  
//1st step) Get the session object    
Properties props = new Properties();  
props.put("mail.smtp.host", "mail.javatpoint.com");//change accordingly  
props.put("mail.smtp.auth", "true");  
Session session = Session.getDefaultInstance(props,  
 new javax.mail.Authenticator() {  
  protected PasswordAuthentication getPasswordAuthentication() {  
   return new PasswordAuthentication(user,pass);  
//2nd step)compose message  
try {  
 MimeMessage message = new MimeMessage(session);  
 message.setFrom(new InternetAddress(user));  
 message.addRecipient(Message.RecipientType.TO,new InternetAddress(to));  
 //3rd step)send message  
 } catch (MessagingException e) {
