"JNDI name is already in use" in Weblogic 12c with EJB3

I have the following code that I'm trying to deploy as an EJB to WebLogic 12c, but I'm getting an error:

"Error deploying the EJB GeopoliticalServiceBean(Application: campaigner-ejb, EJBComponent: campaigner-service.jar), the JNDI name java:global/campaigner-ejb/campaigner-service/GeopoliticalServiceBean!com.dr_dee_sw.campaigner.service.GeopoliticalServiceLocal is already in use. You must set a different JNDI name in the weblogic-ejb-jar.xml deployment descriptor or corresponding annotation for this EJB before it can be deployed."

public interface GeopoliticalService
{
...
}

@Local
public interface GeopoliticalServiceLocal extends GeopoliticalService
{
}

@Remote
public interface GeopoliticalServiceRemote extends GeopoliticalService
{
}

@TransactionManagement(value = TransactionManagementType.CONTAINER)
@TransactionAttribute(value = TransactionAttributeType.REQUIRED)
@Stateless
public class GeopoliticalServiceBean implements GeopoliticalServiceLocal,GeopoliticalServiceRemote
{
...
}

This is my first app using all annotations, but it still seems fairly straight-forward. What am I missing?
