You don't have to write the code to start the Node. The node-impl-osgi = bundle is watching the SCA enabled OSGi bundles and it will start the Node = when the bundle is started.

Sorry I forgot one question.


I am using this code in order to register CalculatorService as SCA service.=

Is it neccesary this??? Can I put composite and component type in "OSG= I-INF/sca" directory only? =A0I mean have I to write this code? Does T= uscany read these files automatically?




Does TestService need this code too?




Thank you very much.









2009/6/16 <santiago.aranda@telvent.com>


So, I have to attach two files (componentType and composite) to my two diff= erent bundles (TestService and Calculator) and model it as "implementa= tion.osgi". =A0 I have TestService in a bundle I will add these two fi= le and I will design as "implementation.osgi" .

But Calculator Service (this is in other bundle) has three components and t= hey are all "implementation.java" and it is working OK. How can I= put a reference to TestService?? Do I need change "implementation.osg= i" in CalculatorComponent instead "implementation.java"? and= is it neccesary for AddServiceComponent and SubstractService??

I will try a example I will copy my files in the email.

Asunto: Re: Fwd: Problem with "implementation.osgi" reference





To access an OSGi service from the SCA component, you will have to provide<= br> SCA configurations for the OSGi bundle so that it becomes an SCA component<= br> using implementation.osgi and the OSGi service becomes an SCA service so that the Calculator component can wire to that TestService.

There are two SCA files you to provide to model the OSGi bundle as an SCA component.
* bundle.componentType to describe what OSGi services or references are use= d
in the bundle (We potentially have better approach to introspect the OSGi bundle to build this up)
* bundle.composite to configure the component, for example, setting the
bindings.

These files can be in a separate OSGi bundle than the one that owns the
services/references.

Raymond

Hi


I can not understand this sample because there are many new concepts for me= .
For example "bundle.componentType". There is not too much informa= tion about
that . I think I need something more simple. I have attached a picture with=
my idea.


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

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


TestService testService;


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




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


Thank you very mucha

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<= br> tuscany. =A0But Tuscany doesn4t 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 =3D
{http://= eclipse.org/SensorNetworkManagement/src/main/resources/SensorNetworkManagem= ent}SensorNetworkManagement
Service =3D 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 us= ed?




I have tried to change =A0"xmlns" tag, but it doesn4t work.


<sca:component name=3D"PruebaComponent">
=A0 =A0 =A0<sca:implementation.osgi
xmlns=3D"http://docs.oasis-open.org/ns/opencsa/sca/200903"= ;
=A0 =A0 =A0 =A0 =A0 bundleSymbolicName=3D"RegistroService"
=A0 =A0 =A0 =A0 =A0 bundleVersion=3D"1.0.0">
=A0 =A0 =A0 =A0 =A0<sca:properties service=3D"prueba.PruebaImpl&qu= ot;>
=A0 =A0 =A0 =A0 =A0</sca:properties>
=A0 =A0 =A0</sca:implementation.osgi>
=A0 =A0</sca:component>


Thank you very much.

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

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

Hello

I want to use an osgi service as a SCA component. But I can not access to their methods from other Component. =A0I mean I have created a wired instan= ce
to the Osgi Service ($Proxy25). It is not "null" but I can not in= voke to one
method because an error is happening

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

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". T= he second
is the SCA component that is representing to the Osgi Service that I want t= o
recover. This Osgi Service was registered in the Osgi registry by Activator=
class in "RegistroService" bundle.

<sca:component name=3D"SensorNetworkManagementComponent"> =A0<sca:implementation.java
class=3D"es.amivital.sensornetworkmanagement.sca.SensorNetworkManageme= ntServiceImpl"/>
=A0<sca:service name=3D"SensorNetworkManagementService"> =A0 <sca:binding.ws=
uri=3D"http://localhost:8085/SensorNetworkManagementComponen= t"/>
=A0</sca:service>
<sca:reference name=3D"prueba" target=3D"PruebaComponent&= quot;/>
</sca:component>


<sca:component name=3D"Prueba">
=A0 =A0 =A0<sca:implementation.osgi
xmlns=3D"http://tuscany.apache.org/xmlns/sca/1.0"
=A0 =A0 =A0 =A0 =A0 bundleSymbolicName=3D"RegistroService"
=A0 =A0 =A0 =A0 =A0 bundleVersion=3D"1.0.0">
=A0 =A0 =A0 =A0 =A0<sca:properties service=3D"prueba.PruebaImpl&qu= ot;>
=A0 =A0 =A0 =A0 =A0</sca:properties>
=A0 =A0 =A0</sca:implementation.osgi>
</sca:component>

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

public class SensorNetworkManagementServiceImpl =A0implements
SensorNetworkManagementService {
private Prueba prueba;
public Prueba getPrueba() {
return prueba;
}
@Reference
public void setPrueba(Prueba prueba) {
this.prueba =3D prueba;
}
}

**Java code =A0 =A0 =A0 --> The second component. It is another bundle t= hat 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 don4t know if they are neccesary .
