Method Detail

injectJavaEEResources

void injectJavaEEResources(Object managedBeanInstance)

Container where OWB is deployed must responsible for injecting Java EE resources defined by this managed bean. This includes, field and method injections. How to inject those resources are defined by Java EE specification.

This is only used for ManagedBean classes. It is not for injection Session Beans or any other Java EE components. Because those are already injected by the related container, for example EJB Container, Web Container etc.

Parameters:

managedBeanInstance - managed bean instance

getResourceReference

<X,T extends Annotation> X getResourceReference(ResourceReference<X,T> resourceReference)

Gets resource for the given resource reference.

This method is used for getting individual resource references that are defined by the ManagedBean producer fields. For example;

Type Parameters:

T - resource type, @EJB, @Resource, @WebServiceRef, @PersistenceContext or @PersistenceUnit

Parameters:

resourceReference -

Returns:

resource for the given resource reference
