To send an email using a JSP, you should have the JavaMail API and the Java Activation Framework (JAF) installed on your machine.
You can download the latest version of JavaMail (Version 1.2) from the Java's standard website.
You can download the latest version of JavaBeans Activation Framework JAF (Version 1.0.2) from the Java's standard website.
Download and unzip these files, in the newly-created top-level directories. You will find a number of jar files for both the applications. You need to add the mail.jar and the activation.jar files in your CLASSPATH.
Send a Simple Email
Here is an example to send a simple email from your machine. It is assumed that your localhost is connected to the Internet and that it is capable enough to send an email. Make sure all the jar files from the Java Email API package and the JAF package are available in CLASSPATH.
Example
<%@ page import = "java.io.*,java.util.*,javax.mail.*"%>
<%@ page import = "javax.mail.internet.*,javax.activation.*"%>
<%@ page import = "javax.servlet.http.*,javax.servlet.*" %>
<%
String result;
// Recipient's email ID needs to be mentioned.
String to = "[email protected]";
// Sender's email ID needs to be mentioned
String from = "[email protected]";
// Assuming you are sending email from localhost
String host = "localhost";
// Get system properties object
Properties properties = System.getProperties();
// Setup mail server
properties.setProperty("mail.smtp.host", host);
// Get the default Session object.
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!");
// Now set the actual message
message.setText("This is actual message");
// Send message
Transport.send(message);
result = "Sent message successfully....";
} catch (MessagingException mex) {
mex.printStackTrace();
result = "Error: unable to send message....";
}
