Referencing a Declarative Service on Karaf via Annotations - apache-camel

Question

I fail to correctly reference a service interface with the #Reference Annotation.
public class TestServiceProcessor implements Processor {
#Reference
private TestService testService;
The Service is up and running on the Karaf Instance and i can reference it with the blueprint file which does work fine.
<bean id="translateOIDs"
class="com.test.TestServiceProcessor">
<property name="TestService" ref="testservice" />
</bean>
<reference id="testservice"
interface="com.test.TestService"/>
The Service has been set up with the OSGI Component Annotations.
I already installed the scr feature and camel-scr on Karaf.
I tried using the field strategy as well as the Event Strategy.
Do i need to further configure the Karaf Instance or am i using the #Reference Annotation in a wrong way?

Answer 1

First you need to install the scr feature to enable declarative services. I guess you mean this with "src" feature.
Apart from this #Reference only works in DS components. So you class TestServiceProcessor must be annotated with #Component ... but then it can not be used in blueprint. DS and blueprint are mutually exclusive.
What you can do instead is leverage the http://aries.apache.org/modules/blueprint-maven-plugin.html.
In this case you need to annotate the bean class with #Named and do the inject with #Inject. You can then also reference annotated beans from the regular blueprint context by their id which can be set using #Named("yourid").
