JCA Email Connection

Custom JavaEE 8 jca resource adapter for connecting to mail servers

build and run :

TomEE 8
mvn clean compile install ; (cd ear-module/ ; mvn tomee:run)

Liberty/OpenLiberty
mvn clean compile install ; (cd ear-module/ ; mvn liberty:run)

Example Inbound Implementation :
Note: Inbound currently use imaps protocol , target mail server must supported idle connection.

@MessageDriven(
        activationConfig = {
                @ActivationConfigProperty(propertyName = "name", propertyValue = "Google Gmail"),
                @ActivationConfigProperty(propertyName = "hostname", propertyValue = "imap.gmail.com"),
                @ActivationConfigProperty(propertyName = "port", propertyValue = "993"),
                @ActivationConfigProperty(propertyName = "username", propertyValue = "USERNAME"),
                @ActivationConfigProperty(propertyName = "password", propertyValue = "PASSWORD")
        }
)
public class GoogleGmailMDB implements MailListener {
    private static final Logger logger = Logger.getLogger(GoogleGmailMDB.class.getName());

    @Override
    public void receiveEmail(Email email) {
        logger.info("[Google Gmail] Receive message subject: [" + email.getSubject() + "]");
    }
}

Example Outbound Implementation :
liberty/openLiberty configuration (server.xml) :

<connectionFactory jndiName="eis/outlookSmtpConnection">
        <properties.jca-application.jca-resourceAdapter
                debug="true"
                hostname="smtp-mail.outlook.com"
                portNumber="587"
                username="USERNAME"
                password="PASSWORD"/>
</connectionFactory>

TomEE 8 configuration (server.xml) :

<Resource id="eis/outlookSmtpConnection" type="ir.moke.jca.api.SmtpConnectionFactory"
              class-name="ir.moke.jca.adapter.SmtpManagedConnectionFactory">
        ResourceAdapter=EmailResourceAdapter
        TransactionSupport=none
        debug=true
        hostname=smtp-mail.outlook.com
        portNumber=587
        username=USERNAME
        password=PASSWORD
</Resource>

now example connectionFactory usage:

@Path("email")
@Produces(MediaType.APPLICATION_JSON)
@Consumes(MediaType.APPLICATION_JSON)
public class SendEmailApi {

    @Resource(name = "eis/outlookSmtpConnection")
    private SmtpConnectionFactory scf;

    @Path("send")
    @POST
    public void sendEmail(Email email) {
        try {
            SmtpConnection smtpConnection = scf.getConnection();
            smtpConnection.sendEmail(email);
        } catch (ResourceException e) {
            e.printStackTrace();
        }
    }
}

send email:

curl -X POST -H "Content-Type: application/json" http://localhost:8080/api/v1/email/send -d '{"subject":"Hello dear !","recipientList" : ["user@domain.com"],"content":"How are you ?","contentType":"text/plain"}'
