Sending Email From Your Application Using Java Mail

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 JavaBeans^TM Activation Framework extension or JAF (javax.activation). It is available at http://java.sun.com/beans/glasgow/jaf.html.

import javax.mail.*; import javax.mail.internet.*; import java.util.*; public void postMail( String recipients[ ], String subject, String message , String from) throws MessagingException {     boolean debug = false;      //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
