Edit conf/<yourconfig>/jboss.jcml and find Mail Service MBean (almost on the bottom).

a) Replace the User and Password attributes values with the user name and password used to connect to your mail server. You can find these values in your mail program. The mail service will use this account to send mails, so be sure that this mail account works properly (test it with your mail program for example).

b) Replace the ConfigurationFile attribute value with the file containing the mail settings. Default is "mail.properties", which is also in the conf/<yourconfig> directory. This file will be edited in step 2.

c) Replace the JNDIName attribute value with the JNDI name for your mail session. The default is "Mail". This JNDI name will be used in jboss.xml to identify the resource. This is explained in more detail in step 4.

Edit the mail properties file you identified in step 1b. By default, this is conf/<yourconfig>/mail.properties.

Edit the following lines:

 
     mail.user = sa005697    // the user to connect with; same as in step 1a
     mail.pop3.host = pop3.wolmail.nl        // the pop host to store the mail on
     mail.smtp.host = smtp.wolmail.nl        // the smtp host to send the mail to 
     mail.from = Memoirs@gamesphere.com      // the 'from' field that is filled in by default in e-mails
     

You can find most value in your mail program. You might want to inspect the JavaMail specification for more details.

The last line, mail.debug, should be set to 'true' for now. This will provide you with verbose debugging information. Once you have everything running correctly, you can set it to false.

Edit the ejb-jar.xml of the EJB that uses the mail service. In your EJB, specify a <resource-ref> like this:

<ejb-jar>
     <description>JBoss JavaMail Sample Application</description>
     <display-name>Mailer EJB</display-name>
     <enterprise-beans>
       <session>
         <ejb-name>Mailer</ejb-name>
         <home>org.jboss.docs.javamail.MailerHome</home>
         <remote>org.jboss.docs.javamail.Mailer</remote>
         <ejb-class>org.jboss.docs.javamail.MailerBean</ejb-class>
         <session-type>Stateless</session-type>
         <transaction-type>Container</transaction-type>
       </session>
     </enterprise-beans>
     <resource-ref>
       <res-ref-name>mail/Mail</res-ref-name> 
       <res-type>javax.mail.Session</res-type> 
       <res-auth>Container</res-auth> 
     </resource-ref> 
</ejb-jar>
     

This will tell the EJB container that the EJB uses a javax.mail.Session resource named mail/MyMail and that authorization is container managed.

You can change the name if you like, but be sure to use the same name in step 6, in the code example.

Edit the jboss.xml of the EJB that uses the mail service. If you don't have this file, create it and place it in the same directory as the ejb-jar.xml of the EJB. This file is JBoss specific and tells JBoss how to map the mail resource to the mail service provider in JBoss. In this file, specify a <resource-manager> like this:

 
<jboss>
  <enterprise-beans>
    <session>
      <ejb-name>Mailer</ejb-name>
      <jndi-name>Mailer</jndi-name>
    </session>
  </enterprise-beans>
  <resource-managers>
    <resource-manager>
      <res-name>mail/Mail</res-name> 
      <res-jndi-name>Mail</res-jndi-name> 
    </resource-manager> 
  </resource-managers> 
</jboss>
     

The name that you specify here is the name that you specified in step 3. The JNDI name that you specify here is the name that you specified in step 1c.

Code example This code example assumes that you are working from inside a JBoss container. For example, this is the case if the code is placed in a JBoss managed SessionBean.

 
package org.jboss.docs.javamail;
import java.util.Date;
import javax.ejb.SessionBean;
import javax.naming.InitialContext;
import javax.mail.Session;
import javax.mail.internet.MimeMessage;
import javax.mail.internet.InternetAddress;
import javax.mail.Transport;
import javax.mail.Address;
import javax.mail.Message;
import javax.rmi.PortableRemoteObject;

public class MailerBean implements SessionBean {
    public void ejbCreate() {}
    
    public void ejbPostCreate() {}
    
    public void sendMail(String address) throws java.rmi.RemoteException {
	Session session = null;
	try {
	    session = (Session)PortableRemoteObject.narrow(new InitialContext().lookup("java:Mail"), Session.class);
	} catch (javax.naming.NamingException e) {
	    e.printStackTrace();
	}
                             
	try {
	    MimeMessage m = new MimeMessage(session);
	    m.setFrom();
	    Address[] to = new InternetAddress[] {
		new InternetAddress(address)
	    };
	    m.setRecipients(Message.RecipientType.TO, to);
	    m.setSubject("JavaMail Test");
	    m.setSentDate(new Date());
	    m.setContent("Test from inside EJB Using JBoss", 
			 "text/plain");
	    Transport.send(m);
	} catch (javax.mail.MessagingException e) {
	    e.printStackTrace();
	}               
    }

    public void ejbActivate() {}
    public void ejbPassivate() {}
    public void ejbRemove() {}
    public void setSessionContext(javax.ejb.SessionContext ec) {}
}
   

Using the JavaMail service with mail servers that require POP authentication before SMTP You can do this by using:

 
             import javax.mail.Store;

             Store s = session.getStore();
             s.connect(); // POP authentication
             Transport.send(m);
