I guess composite variable is not null in the first iteration. But = it is=20 null when composite =3D = (Composite)resolvedArtifact.getModel(); is=20 executed.

This code of CalculatorServiceImpl

       public int add(int param1, int param2) = {
System.out.println = (testService.sayHello());=20  --> I have an error when this line is executed

@Reference

This is the error . The testService instance is not null but it is = not=20 wired to TestService.  I have registered the Osgi Service registry = using=20 this code in the Activator of TestService bundle. I think this is=20 neccesary.

It=20 is necessary to have a bundle.composite file in TestService?? and=20 bundle.componentType??

<rfeng>Yes</rfeng>=20



Thank you very=20 = much
-----------------------------------------------------------------= --





Tuscany=20 checks the OSGi bundle based on one of the following patterns:
* An = "SCA-Composite" header in the MANIFEST.MF. It points to an SCA = composite file=20 within the bundle.
* Any files under OSGI-INF/sca.

In your = case, the=20 first bundle contains three java components. The second bundle = contains one=20 OSGi component.  There are a few options to get them work = together=20 (CalculatorService with a reference to TestService).

Option = 1:
1)=20 Place bundle.composite under OSGI-INF/sca in the calculator bundle. = The=20 composite contains 4 components: 3 java components and 1 OSGi=20 component.
The @target for CalculatorService component's = testService=20 reference will be TestService/<serviceName>.

2) Place=20 bundle.componentType under OSGI-INF/sca in the test service=20 bundle.
Alternatively, you have place the file as=20 OSGI-INF/sca/<bundleSymbolicName>/bundle.componentType in the = calculator=20 bundle.

In this case, we are going to start one = Node.

Option=20 2:
1) Place bundle.composite under OSGI-INF/sca in the calculator = bundle.=20 The composite contains 3 java components
2) Place bundle.composite = under=20 OSGI-INF/sca in the test service bundle. The composite contains 1 OSGi = component.
3) Place bundle.componentType under OSGI-INF/sca in the = test=20 service bundle.

In this case, we are going to start two nodes. = You can=20 configure the CalculatorService.testService reference and the OSGi = service to=20 use the same binding (such as RMI, or WS) to communicate. Make sure = the=20 interface is remotable. binding.sca is not working=20 yet.

So, I have to = attach=20 two files (componentType and composite) to my two different bundles=20 (TestService and Calculator) and model it as "implementation.osgi". =   I=20 have TestService in a bundle I will add these two file and I will = design as=20 "implementation.osgi" .

But Calculator Service (this is in = other=20 bundle) has three components and they are all "implementation.java" = and it is=20 working OK. How can I put a reference to TestService?? Do I need = change=20 "implementation.osgi" in CalculatorComponent instead = "implementation.java"?=20 and is it neccesary for AddServiceComponent and = SubstractService??

I=20 will try a example I will copy my files in the email.

Asunto: = Re: Fwd:=20 Problem with "implementation.osgi" reference




To = access an=20 OSGi service from the SCA component, you will have to provide
SCA=20 configurations for the OSGi bundle so that it becomes an SCA=20 component
using implementation.osgi and the OSGi service becomes an = SCA=20 service so
that the Calculator component can wire to that=20 TestService.

There are two SCA files you to provide to model = the OSGi=20 bundle as an SCA
component.
* bundle.componentType to describe = what OSGi=20 services or references are used
in the bundle (We potentially have = better=20 approach to introspect the OSGi
bundle to build this up)
*=20 bundle.composite to configure the component, for example, setting=20 the
bindings.

These files can be in a separate OSGi bundle = than the=20 one that owns=20 the
services/references.

Thanks,
Raymond

Hi


I can=20 not understand this sample because there are many new concepts for = me.
For=20 example "bundle.componentType". There is not too much information=20 about
that . I think I need something more simple. I have attached = a=20 picture with
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

The @target is = pointing to a=20 wrong componentName/serviceName. It should be

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

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.
