The confirmer example application demonstrates how to use an injected JavaMail session to send a confirmation email. If you've ever ordered a product from a web site, you've probably received an email confirming your order. The ConfirmerBean class demonstrates how to send email from an enterprise bean. Like a database connection, a mail session is a resource. In the Application Server, a mail session is called a JavaMail resource. The resource is injected into the class using @Resource and specifying the JNDI name of the resource. The type of the session field is javax.mail.Session. @Resource(name="mail/myMailSession") private Session session; After calling several set methods on the Message object, sendNotice invokes the send method of the javax.mail.Transport class to send the message. The source code for the sendNotice method follows. public void sendNotice(String recipient) { try { Message message = new MimeMessage(session); message.setFrom(); message.setRecipients(Message.RecipientType.TO, InternetAddress.parse(recipient, false)); message.setSubject("Test Message from ConfirmerBean"); DateFormat dateFormatter = DateFormat .getDateTimeInstance(DateFormat.LONG, DateFormat.SHORT); Date timeStamp = new Date(); String messageText = "Thank you for your order." + '\n' + "We received your order on " + dateFormatter.format(timeStamp) + "."; message.setText(messageText); message.setHeader("X-Mailer", mailer); message.setSentDate(timeStamp); // Send message Transport.send(message); logger.info("Mail sent to " + recipient + "."); } catch (MessagingException ex) { ex.printStackTrace(); logger.info("Error in ConfirmerBean for " + recipient); } } Running the confirmer Example ApplicationTo run the confirmer example, follow these steps, as described in the following sections:
Creating a Mail SessionTo create a mail session in the Application Server using the Admin Console, follow these steps:
Building, Packaging, and Deploying confirmer in NetBeans 5.5Follow these instructions to build, package, and deploy the confirmer example to your Application Server instance using the NetBeans 5.5 IDE.
This builds and packages the application into confirmer.ear, located in <INSTALL>/javaeetutorial5/examples/ejb/confirmer/dist, and deploys this EAR file to your Application Server instance. Building, Packaging, and Deploying confirmer Using AntTo build and package the confirmer example, do the following:
This compiles the source code and creates an EAR file, confirmer.ear, in the dist directory. To deploy confirmer.ear, type the following command in a terminal window: ant deploy Running the Client in NetBeans 5.5By default, the client sends a message to pig.bodine@example.com, a fictional email address. To change the email address in NetBeans 5.5, do the following:
To run the client in NetBeans 5.5, right-click the confirmer project in the Projects pane and select Run Project. You should see the following line when the client has successfully sent the test message: ... Message sent to pig.bodine@example.com. ... Running the Client Using AntBy default, the client sends a message to pig.bodine@example.com, a fictional email address. To change the email address, set the app-client.args property in <INSTALL>/examples/ejb/confirmer/nbproject/project.properties to the email address to which you'd like the test message sent. For example: app-client.args=duke@example.com To retrieve the client JAR and run the client, enter the following command in a terminal: ant run You should see the following line when the client has successfully sent the test message: [exec] Message sent to pig.bodine@example.com. If you changed the target email address, the test message should arrive in the user's inbox in a few moments. |
