Now a Day's informing the Clients about the successful updation of data or sending other automated information form your Java Programs, either from your Servlets or from your Applications has become a requirement, more than a feature. Here we show how to use the Java Mail API to send a Mail. To Test Program all you need to have is a SMTP address (Which your ISP Provides).
Before Using this Program, you need to have Javasoft's JavaMail class files which can be downloaded from here http://www.javasoft.com/products/javamail/index.html
You will also need the JavaBeansTM Activation Framework extension or JAF (javax.activation). It is available at http://java.sun.com/beans/glasgow/jaf.html.
//Set the host smtp address
Properties props = new Properties();
props.put("mail.smtp.host", "smtp.jcom.net");
// create some properties and get the default Session
Session session = Session.getDefaultInstance(props, null);
session.setDebug(debug);
// create a message
Message msg = new MimeMessage(session);
// set the from and to address
InternetAddress addressFrom = new InternetAddress(from);
msg.setFrom(addressFrom);
InternetAddress[] addressTo = new InternetAddress[recipients.length];
for (int i = 0; i < recipients.length; i++)
{
addressTo[i] = new InternetAddress(recipients[i]);
}
msg.setRecipients(Message.RecipientType.TO, addressTo);
// Optional : You can also set your custom headers in the Email if you Want
msg.addHeader("MyHeaderName", "myHeaderValue");
// Setting the Subject and Content Type
msg.setSubject(subject);
msg.setContent(message, "text/plain");
Transport.send(msg);
}
To Send a Email, from your Program, just call the above method, With the following parameters,
String to -- Email Address of the Recipient
String subject -- Email Subject
String message -- Content or Body of the Message
String from -- Your (Senders) Email Address
smtp.jcom.net -- Replace this with your ISP's SMTP address.
