Hello guys,

I'm using gemini blueprint in a WAB to discover services exposed by somes bundles deployed on JBoss OSGi container and all works fine, expect the reference-listener on the service consumed.

Here's my use case :

I have the bundle myServiceImpl which expose one service with gemini blueprint :

(file META-INF/spring/app-context.xml)

...
<bean id="myServiceBean" class="xxx.yyy.MyServiceImpl" init-method="startService" destroy-method="stopService"/>

<osgi:service id="myServiceOsgi" ref="myServiceBean" interface="xxx.yyy.IMyService" />
...

I have a WAB myWab which consumes the service exposed as below :

(file src/main/webapp/WEB-INF/spring/app-context.xml)

...
<bean class="xxx.yyy.ServiceListener" id="myServiceListener" />

<osgi:list id="myServicesOsgi" interface="xxx.yyy.IMyService">
          <osgi:reference-listener bind-method="myBind" unbind-method="myUnbind" >
                    <ref bean="myServicesListener"/>
          </osgi:reference-listener>
</osgi:list>
...

(file src/main/java/xxx/yyy/zzz/ServiceListener.java)

public class ServiceListener {

          public void myBind(IMyService myService, Map<String, Object> properties) throws Exception {
                    System.out.println("A binding is normally done");
          }

          public void myUnbind(Object myService, Map<String, Object> properties) throws Exception {
                    System.out.println("An unbinding is normally done");
          }
}

(file src/main/java/xxx/yyy/controller/FileUploadController.java)

@Controller
public class FileUploadController {

          private List<IMyService> myServices;

          @Autowired
          protected FileUploadController(@Value("#{myServicesOsgi}") List<IMyService> myServices) {
                    super();
                    this.myServices = myServices;
          }

          @RequestMapping(value="/post", method = RequestMethod.POST)
          @ResponseBody
          public String upload(MultipartFile file) throws IOException, Exception {

                    SomeClass someClass = new SomeClass(1L, file.getInputStream());

                    for (Iterator<IMyService> iterator = myServices.iterator(); iterator.hasNext();) {
                              IMyService service = (IMyService) iterator.next();
                              service.doSomeStuff(invoice);
                    }

                    return file.getOriginalFilename();
          }
}

When I upload a file on my IHM, I can see in the logs that the service defined by myServiceImpl is well called (and when others services are exposed by others bundle, these services are called too)

However, If i stop the bundle myServiceImpl, the sentence "An unbinding is normally done" is not printed and so the listener seems not to be called.

So I tried to do this (listening the services publication) outside of the Wab to be sure it wasn't an implementation problem.

I have done a third bundle, named myServiceConsumer with exactly the same classes than the Wab :

The class ServiceListener in a package src/main/java/xxx/yyy/zzz/

The spring/gemini file in src/main/ressources/META-INF/spring

I deployed this bundle on JBoss and when I start/stop myServiceImpl, I'm able to see the output as expected : "A binding is normally done"/"An unbinding is normally done".

Any ideas ?

Thanks in advance
