Now visit http://localhost:8080/SendEmail.jsp, and it will send an email to abcd@gmail.com and display the following result: Send Email using JSP Result: Sent message successfully.... If you want to send an email to multiple recipients, the following method can be used to specify multiple email addresses: void addRecipients(Message.RecipientType type, Address[] addresses)throws MessagingException The parameters are described as follows: * type: This value will be set to TO (recipient), CC, or BCC.

Session mailSession = Session.getDefaultInstance(properties); try{ // Create a default MimeMessage object. MimeMessage message = new MimeMessage(mailSession); // Set From: header field of the header. message.setFrom(new InternetAddress(from)); // Set To: header field of the header. message.addRecipient(Message.RecipientType.TO, new InternetAddress(to)); // Set Subject: header field message.setSubject("This is the Subject Line!"); // Set HTML message message.setContent("

This is actual message

", "text/html" ); // Send message Transport.send(message); result = "Sent message successfully...."; }catch (MessagingException mex) { mex.printStackTrace(); result = "Error: unable to send message...."; } %>
