All Implemented Interfaces:

EjbReferenceResolver

public class FirstMatchEjbReferenceResolver
extends EjbReferenceResolverBase
implements EjbReferenceResolver

FirstMatchEjbReferenceResolver An EJB Reference resolver which will return the first match found. In cases where the reference may be non-deterministic this implementation will stop when the reference requirements are satisfied NonDeterministicInterfaceException is therefore avoided when a common interface is used across DeploymentUnits in the same DU Hierarchy; very simply the first DU which is able to resolve the reference (without conflicting with possible references to other EJBs within that DU) will be used.
