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

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

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

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

I have tried to change  "xmlns" tag, but it doesn´t work.

  <sca:component name="PruebaComponent">
        <sca:implementation.osgi xmlns="http://docs.oasis-open.org/ns/opencsa/sca/200903"
            <sca:properties service="prueba.PruebaImpl">                

Thank you very much.

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

    Are you using Tuscany/SCA 2.x or 1.x?

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

    --->Unable to create SCA binding invoker for local target SensorNetworkManagementComponent
reference prueba (bindingURI=null operation=sayHello) 

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

     <sca:component name="SensorNetworkManagementComponent"> 
        <sca:implementation.java class="es.amivital.sensornetworkmanagement.sca.SensorNetworkManagementServiceImpl"/>

        <sca:service name="SensorNetworkManagementService">       
         <sca:binding.ws uri="http://localhost:8085/SensorNetworkManagementComponent"/>

      <sca:reference name="prueba" target="PruebaComponent"/> 

      <sca:component name="Prueba"> 
            <sca:implementation.osgi xmlns="http://tuscany.apache.org/xmlns/sca/1.0" 
                <sca:properties service="prueba.PruebaImpl">                 

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

    public class SensorNetworkManagementServiceImpl  implements SensorNetworkManagementService
    private Prueba prueba; 
    public Prueba getPrueba() { 
    return prueba; 
    public void setPrueba(Prueba prueba) { 
    this.prueba = prueba; 

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

    public interface Prueba { 
    public abstract String sayHello(); 


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

    I have read something about anottations like @AllowsPassByReference or @Scope, but I don´t
know if they are neccesary .
