Hello there,
Am using JBoss 5.1.0GA and JDK 1.5.0_19 on OS X Leopard.
Created a working [SendMailServlet|http://tinyurl.com/SendMailServletCode].
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(a)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(a)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.doPost(MailController.java:42)
| [STDERR] at com.myapp.MailController.doGet(MailController.java:26)
|
Why am I getting this java.net.ConnectException: Connection refused exception?
Happy programming,
Mike
