Trying to send e-mail using JavaMail, JBoss 5, and JNDI

[Michael K. Wilson]

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("[e-mail]", "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="[e-mail]"/>
        <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

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

Happy programming,

I fixed it! It works now!

Solution: Replace the mail.jar file on JBoss with the newest one from Sun and edit the mail configuration file to reflect port 465.

The JavaMail 1.4ea jar is what comes bundled with JBoss 5.1.0.GA inside:

$JBOSS_HOME/common/lib

Replaced it with 1.4.2 and then changed some of the xml config parameters around.

Debug output:
