------------------------------------------------------------
Do not try to use the low-level OSGI APIs from within your Java code, since
you'd then need to deal with all of the dynamism of the OSGI environment.
Instead, use the OSGI declarative services feature to do dependency injection.
YouTubeDistributionService should include a reference to WorkflowService and a
setter: protected void setWorkflowService(WorkflowService workflowService)
{this.workflowService=workflowService;}. It is not your job to call this
setter, it will be called for you.
In the service registration
(src/main/resources/OSGI-INF/distribution-service-youtube.xml), you'll need to
add a reference to the workflow service:
<reference name="WORKFLOW"
interface="org.opencastproject.workflow.api.WorkflowService" cardinality="1..1"
policy="static" bind="setWorkflowService"/>
These inter-service references are all over the place, in almost every service
in Matterhorn, so pick any OSGI-INF folder to find examples.
