ServiceMix dependencies

I have just fixed a small bug in ServiceMix (SM-865) and this makes ServiceMix a *very* lightweight ESB. The bare minimum dependencies to run the following example are:

• servicemix-core
• servicemix-jbi
• servicemix-services
• backport-util-concurrent
• spring
• xbean-spring

The example I ran is very simple, and of course dependencies need to be added depending on the JBI components you use. Anyway, here is the servicemix.xml file:

<beans xmlns:sm="http://servicemix.apache.org/config/1.0"
     xmlns:test="urn:test">
  <sm:container id="jbi" embedded="true">                 
    <sm:activationSpecs>
      <sm:activationSpec service="test:echo">
        <sm:component>
          <bean class="org.apache.servicemix.components.util.EchoComponent" />
        </sm:component>
      </sm:activationSpec>
    </sm:activationSpecs>
  </sm:container>
  <sm:client id="client" container="#jbi" />
</beans>

And here is the java code used:

import javax.jbi.messaging.InOut;
import javax.xml.namespace.QName;
import org.apache.servicemix.client.ServiceMixClient;
import org.apache.servicemix.jbi.jaxp.StringSource;
import org.apache.xbean.spring.context.ClassPathXmlApplicationContext;
import org.springframework.context.ApplicationContext;

public class Main {
   public static void main(String[] args) throws Exception {
       ApplicationContext context = new ClassPathXmlApplicationContext("servicemix.xml");
       ServiceMixClient client = (ServiceMixClient) context.getBean("client");
       InOut me = client.createInOutExchange();
       me.setService(new QName("urn:test", "echo"));
       me.getInMessage().setContent(new StringSource("world"));
       client.sendSync(me);
       System.err.println(me);
   }
}

This is the results of the work that has been done for the 3.1 release. The next step is to use the standard JBI components from ServiceMix ...
