Hi,

I am just experimenting a little bit with the implementation.osgi stuff
taking some samples as start...

I would like to have the following scenario. Two bundles are started in the
OSGi framework and are registered in for SCA. One bundle is consuming a
service that is implemented by the other bundle. I do not get an idea how
this can be done or maybe it is not possible.

So from the samples I have an OSGI-INF/sca folder with a bundle.composite
and a bundle.componentType file.

bundle.composite:

<composite xmlns="http://docs.oasis-open.org/ns/opencsa/sca/200912"
    xmlns:tuscany="http://tuscany.apache.org/xmlns/sca/1.1"
    xmlns:xsd="http://www.w3.org/2001/XMLSchema"
    targetNamespace="http://calculator.dosgi"
    name="SMSComposite">

    <component name="SMSComponent">
        <tuscany:implementation.osgi
bundleSymbolicName="DeveloperGardenSDK.SMS" bundleVersion="0.0.1" />
        <service name="smsService">
            <binding.ws uri="http://localhost:8082/SMSService"/>
        </service>
    </component>   
</composite>

bundle.componentType:

<componentType xmlns="http://docs.oasis-open.org/ns/opencsa/sca/200912"
               xmlns:xsd="http://www.w3.org/2001/XMLSchema"
               xmlns:t="http://tuscany.apache.org/xmlns/sca/1.1">
    <service name="smsService">
        <interface.java
interface="de.fhg.fokus.ngni.xposer.see.developergarden.sms.SMS"/>
    </service>
</componentType>

Furthermore the service is registered in the Activator class. The
registration is working and I am also able to consume the service via SOAP.
Now I want to have a second bundle that is able to consume the service.
Following files are created:

bundle.composite:

<composite xmlns="http://docs.oasis-open.org/ns/opencsa/sca/200912"
    xmlns:tuscany="http://tuscany.apache.org/xmlns/sca/1.1"
    xmlns:xsd="http://www.w3.org/2001/XMLSchema"
    targetNamespace="http://calculator.dosgi"
    name="ReminderComposite">
    <component name="ReminderComponent">
        <tuscany:implementation.osgi bundleSymbolicName="Reminder_SCA"
bundleVersion="1.0" />
        <service name="ReminderService">
            <binding.ws uri="http://localhost:8082/ReminderService"/>
        </service>
        <reference name="smsService">
            <binding.ws uri="http://localhost:8082/SMSService"/>
        </reference>
    </component>   
</composite>

bundle.componentType:

<componentType xmlns="http://docs.oasis-open.org/ns/opencsa/sca/200912"
               xmlns:xsd="http://www.w3.org/2001/XMLSchema"
               xmlns:t="http://tuscany.apache.org/xmlns/sca/1.1">
    <service name="ReminderService">
        <interface.java
interface="de.fhg.fokus.ngni.xposer.see.service.sca.reminder.ReminderService
"/>
    </service>
    <reference name="smsService">
        <interface.java
interface="de.fhg.fokus.ngni.xposer.see.developergarden.sms.SMS"/>
    </reference>
</componentType>

Again this service is registered via the Activator class. How I am getting
now the SMS service in the Java Code? I tried some things I have found in
other samples.
So the ReminderService implementation looks like that:

public class ReminderServiceImpl implements ReminderService {        private
SMS smsService;        @Reference    public void setSmsService(SMS
smsService){        this.smsService = smsService;    }     @Override
public boolean startReminder(String user) {        return
smsService.sendSMS("xy", "number", "Hallo", "Reminder");    } }

This structure is taken from another sample I looked at. The smsService is
null at this point.
I know that I could get the SMS service over OSGi reference stuff but I want
to use SCA stuff.

Please tell me if my scenario is wrong (or stupid) or if this is just not
working.

Thanks in advance.

greetings,
Alex
