*=20 bundle.composite to configure the component, for example, setting=20 the

my idea.


** When my SCA service was working = I had a=20 main component
"implementacion.java" with two references to another = two=20 components
(implementation.java). The main component could be = invoked as=20 Web Service.


** Now, I want another reference to a Service=20 (TestService in the picture)
that was registered by another = different=20 bundle. But this is a OSGi bundle,
without SCA information, = Composite file=20 nor ComponentType file. I mean it is
a bundle that is registering a = service=20 in the OSGi registry. I need have a
instance wired to this OSGi = service in=20 the class of the main Component in
order to invoke their=20 methods.


TestService testService;


//I need = testService=20 is not null in order to invoke their=20 methods.
testService.sayHello();




I hope you can=20 understand my problem. You can ask me if you want.


Thank = you very=20 = mucha

Yes, you are right. I was = doing=20 some different tests and I copied you a
wrong composite. I wanted = to see if=20 the change of @target made an error in
tuscany.  But Tuscany = doesn4t=20 recognize this error because I think it
supposes that will be a = "remote=20 Component". I can see this in the = tuscany
trace


ADVERTENCIA:=20 Component reference target not found, it might be a remote
service = running=20 elsewhere in the SCA Domain: Composite =3D
{http://eclipse.org/SensorNetworkManagement/src/main/resou= rces/SensorNetworkManagement}SensorNetworkManagement
Service=20 =3D PruebaComponent



But it is Ok, because the component = I want if=20 an Osgi Service registered in
the Osgi registry.
I have fixed = the error=20 in @target and it is not working yet.


Do you know any = example when=20 an <implementation.osgi> component is used?




I = have=20 tried to change  "xmlns" tag, but it doesn4t=20 work.


<sca:component = name=3D"PruebaComponent">
   =20  <sca:implementation.osgi

Thank you very=20 much.

The @target is = pointing to a=20 wrong componentName/serviceName. It should be
"Prueba" instead of=20 "PruebaComponent" as the component name is "Prueba".

Hello

I want to = use an=20 osgi service as a SCA component. But I can not access to
their = methods from=20 other Component.  I mean I have created a wired instance
to = the Osgi=20 Service ($Proxy25). It is not "null" but I can not invoke to = one
method=20 because an error is happening

--->Unable to create SCA = binding=20 invoker for local target
SensorNetworkManagementComponent reference = prueba=20 (bindingURI=3Dnull
operation=3DsayHello)

This is my = composite file. I=20 want to have to two components. The first had a
reference to the = second and=20 it is normal "implementation.java". The second
is the SCA component = that is=20 representing to the Osgi Service that I want to
recover. This Osgi = Service=20 was registered in the Osgi registry by Activator
class in = "RegistroService"=20 bundle.

<sca:component=20 = name=3D"SensorNetworkManagementComponent">
 <sca:implementa= tion.java
class=3D"es.amivital.sensornetworkmanagement.sca.SensorNetwo= rkManagementServiceImpl"/>
 <sca:service=20 name=3D"SensorNetworkManagementService">
  <sca:binding.ws
uri=3D"http://localhost:8085/SensorNetworkManagementComponent"/>
 </sca:service>
<sca:reference=20 name=3D"prueba"=20 = target=3D"PruebaComponent"/>
</sca:component>


<= sca:component=20 name=3D"Prueba">
   =20  <sca:implementation.osgi
xmlns=3D"http://tuscany.apache.org/xmlns/sca/1.0"
  =  =20       bundleSymbolicName=3D"RegistroService"
  =  =20       bundleVersion=3D"1.0.0">
    =    =20  <sca:properties service=3D"prueba.PruebaImpl">
  =  =20      </sca:properties>
   =20 =  </sca:implementation.osgi>
</sca:component>

*= **The=20 Java code--> The first component.

public class=20 SensorNetworkManagementServiceImpl=20  implements
SensorNetworkManagementService {
private Prueba = prueba;
public Prueba getPrueba() {
return=20 prueba;
}
@Reference
public void setPrueba(Prueba prueba)=20 {
this.prueba =3D prueba;
}
}

**Java code   =    =20 --> The second component. It is another bundle that = is
registering one=20 simple Osgi Service. The interface was

public interface Prueba=20 {
public abstract String = sayHello();

}





This=20 instance (prueba) is not null when an outside client invoke to = the
first=20 component. But if I invoke to one method of this interface, = for
example=20 "prueba.sayHello" I obtained the previous error.

I have read = something=20 about anottations like @AllowsPassByReference or
@Scope, but I = don4t know=20 if they are neccesary . =
