Registering JavaMail as OSGi Service

[ms9580]

Greetings,

I am newbie to both Java and JBoss Fuse world.

Following the footsteps of registering JDBC data sources, I was trying to register a mail smtp in the same fashion. I am hot deploying the following. After deployment I do not see anything under Registered Services for this deployment.

<?xml version="1.0" encoding="UTF-8"?>

<blueprint xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0">

  <bean id="mailSourceLive" class="javax.mail.Session">

      <property name="mail.smtp.host" value="mysmptpip"/>

      <property name="mail.smtp.port" value="25"/>

  </bean>

  <service auto-export="interfaces" ref="mailSourceLive">

    <service-properties>

      <entry key="osgi.jndi.service.name" value="java:mail/MailServer"/>

    </service-properties>

  </service>

</blueprint>

Would appreciate any pointers.

Regards,

Sohail

Hi,

Did you see any exception in the log?

Class java.mail.Session doesn't implement any interface, this probably is the culprit.

Hello Freeman,

Thanks for the response. This is the exception that is appearing ... really beating up myself for not looking at the log in the first place.

Is there a particular class that I should be including in the blueprint file?

Hi,

Class java.mail.Session doesn't have public constructor, you need init-method = "getInstance" to call the factory method to create the instance if you really need it.
