Java EE (Java Enterprise Edition) General Discussion

Hello there,

Am using JBoss 5.1.0GA and JDK 1.5.0_19 on OS X Leopard.

Created a working SendMailServlet.

Have now decided to refactor it into two separate classes (extract out JavaMail code to a separate class and create a ServletController).

Am also trying to use JNDI to access the connection properties in the mail-service.xml configuration file residing in JBoss.

The Mailer class contains the reusable functionality needed to send an e-mail:

public class Mailer {
	private Session mailSession;

	protected void sendMsg(String email, String subject, String body)
	throws MessagingException, NamingException {
		Properties props = new Properties();
		InitialContext ictx = new InitialContext(props);
		Session mailSession = (Session) ictx.lookup("java:/Mail");
//		Session mailSessoin = Session.getDefaultInstance(props);
		String username = (String) props.get("mail.smtps.user");
		String password = (String) props.get("mail.smtps.password");

		MimeMessage message = new MimeMessage(mailSession);
		message.setSubject(subject);
		message.setRecipients(javax.mail.Message.RecipientType.TO,
				javax.mail.internet.InternetAddress.parse(email, false));
		message.setText(body);
		message.saveChanges();

		Transport transport = mailSession.getTransport("smtps");
		try {
			transport.connect(username, password);
			transport.sendMessage(message, message.getAllRecipients());
			Logger.getLogger(this.getClass()).warn("Message sent");
		}
		finally {
			transport.close();
		}
	}
}

The MailController class serves as a standard Java Servlet which invokes the Mailer.class's sendMsg() method:

public class MailController extends HttpServlet {
	/** static final HTML setting for content type */
	private static final String HTML = "text/html";

	myapp/** static final HTML setting for content type */
	private static final String PLAIN = "text/plain";

	public void doGet(HttpServletRequest request, HttpServletResponse response)
	throws ServletException, IOException {
		doPost(request, response);
	}

	public void doPost(HttpServletRequest request, HttpServletResponse response)
	throws ServletException, IOException {
		response.setContentType(PLAIN);
		PrintWriter out = response.getWriter();
		String mailToken = TokenUtil.getEncryptedKey();
		String body = "Hello there, " + "\n\n"
		          + "Wanna play a game of golf?" + "\n\n"
			  + "Please confirm: https://localhost:8443/myapp/confirm?token="
			  + mailToken + "\n\n" + "-Golf USA";
		Mailer mailer = new Mailer();
		try {
			mailer.sendMsg("recipient@gmail.com", "Golf Invitation!", body);
			out.println("Message Sent");
		}
		catch (MessagingException e) {
			e.printStackTrace();
		}
		catch (NamingException e) {
			e.printStackTrace();
		}
	}
}

Have the mail configuration set under $JBOSS_HOME/server/default/deploy/mail-service.xml:

<server>
  <mbean code="org.jboss.mail.MailService" name="jboss:service=Mail">
    <attribute name="JNDIName">java:/Mail</attribute>
    <attribute name="User">user</attribute>
    <attribute name="Password">password</attribute>
    <attribute name="Configuration">
      <configuration>
        <property name="mail.store.protocol" value="pop3"/>
        <property name="mail.transport.protocol" value="smtp"/>
        <property name="mail.user" value="user"/>
        <property name="mail.pop3.host" value="pop3.gmail.com"/>
        <property name="mail.smtp.host" value="smtp.gmail.com"/>
        <property name="mail.smtp.port" value="25"/>
        <property name="mail.from" value="user@gmail.com"/>
        <property name="mail.debug" value="true"/>
      </configuration>
    </attribute>
    <depends>jboss:service=Naming</depends>
  </mbean>
</server>

web.xml (Deployment Descriptor):

<servlet>
    <servlet-name>MailController</servlet-name>
    <servlet-class>com.myapp.MailController</servlet-class>
</servlet>

<servlet-mapping>
    <servlet-name>MailController</servlet-name>
    <url-pattern>/sendmail</url-pattern>
</servlet-mapping>

This is what is outputted when I start JBOSS and click point my browser to:

https://localhost:8443/myapp/sendmail

[STDERR] 	at com.myapp.MailController.doGet(MailController.java:26)

Why am I getting this java.net.ConnectException: Connection refused exception?

Happy programming,

Mike
