The JavaMail API can found here.
You need 2 jars : mail.jar and activation.jar.
It's a good idea to read the JavaMail FAQ.
Simple email
import javax.mail.*;
import javax.mail.internet.*;
import java.util.Properties;
class SimpleMail {
public static void main(String[] args) throws Exception{
Properties props = new Properties();
props.setProperty("mail.transport.protocol", "smtp");
props.setProperty("mail.host", "mymail.server.org");
props.setProperty("mail.user", "emailuser");
props.setProperty("mail.password", "");
Session mailSession = Session.getDefaultInstance(props, null);
Transport transport = mailSession.getTransport();
MimeMessage message = new MimeMessage(mailSession);
message.setSubject("Testing javamail plain");
message.setContent("This is a test", "text/plain");
message.addRecipient(Message.RecipientType.TO,
new InternetAddress("elvis@presley.org"));
transport.connect();
transport.sendMessage(message,
message.getRecipients(Message.RecipientType.TO));
transport.close();
}
}
HTML Email
import javax.mail.*;
import javax.mail.internet.*;
import java.util.Properties;
class SimpleHTMLMail {
public static void main(String[] args) throws Exception{
Properties props = new Properties();
props.setProperty("mail.transport.protocol", "smtp");
props.setProperty("mail.host", "mymail.server.org");
props.setProperty("mail.user", "emailuser");
props.setProperty("mail.password", "");
Session mailSession = Session.getDefaultInstance(props, null);
Transport transport = mailSession.getTransport();
MimeMessage message = new MimeMessage(mailSession);
message.setSubject("Testing javamail html");
message.setContent
("This is a test <b>HOWTO<b>", "text/html; charset=ISO-8859-1");
message.addRecipient(Message.RecipientType.TO,
new InternetAddress("elvis@presley.org"));
transport.connect();
transport.sendMessage(message,
message.getRecipients(Message.RecipientType.TO));
transport.close();
}
}
Email with attachment
import javax.mail.*;
import javax.mail.internet.*;
import javax.activation.FileDataSource;
import javax.activation.DataHandler;
import java.util.Properties;
class SimpleMailWithAttachment {
public static void main(String[] args) throws Exception{
boolean debug = false;
Properties props = new Properties();
props.setProperty("mail.transport.protocol", "smtp");
props.setProperty("mail.host", "mymail.server.org");
props.setProperty("mail.user", "emailuser");
props.setProperty("mail.password", "");
Session mailSession = Session.getDefaultInstance(props, null);
mailSession.setDebug(debug);
Transport transport = mailSession.getTransport();
MimeMessage message = new MimeMessage(mailSession);
message.setSubject("Testing javamail with attachment");
MimeBodyPart textPart = new MimeBodyPart();
textPart.setContent("<h1>Check attachment</h1>", "text/html");
MimeBodyPart attachFilePart = new MimeBodyPart();
FileDataSource fds =
new FileDataSource("SimpleMailWithAttachment.java");
attachFilePart.setDataHandler(new DataHandler(fds));
attachFilePart.setFileName(fds.getName());
Multipart mp = new MimeMultipart();
mp.addBodyPart(textPart);
mp.addBodyPart(attachFilePart);
message.setContent(mp);
message.addRecipient(Message.RecipientType.TO,
new InternetAddress("elvis@presley.org"));
transport.connect();
transport.sendMessage(message,
message.getRecipients(Message.RecipientType.TO));
transport.close();
}
}
