Method Detail

resolveEjb

java.lang.Object resolveEjb(InjectionPoint injectionPoint,
                            NamingContext namingContext)

Resolve the value for the given @EJB injection point

Parameters:

injectionPoint - the injection point metadata

Returns:

an instance of the EJB

Throws:

java.lang.IllegalArgumentException - if the injection point is not annotated with @EJB, or, if the injection point is a method that doesn't follow JavaBean conventions

java.lang.IllegalStateException - if no EJBs can be resolved for injection

resolvePersistenceContext

java.lang.Object resolvePersistenceContext(InjectionPoint injectionPoint,
                                           NamingContext namingContext)

Resolve the value for the given @PersistenceContext injection point

Parameters:

injectionPoint - the injection point metadata

namingContext - the pluggable Web Beans JNDI lookup facility

Returns:

an instance of the persistence unit

Throws:

java.lang.IllegalArgumentException - if the injection point is not annotated with

java.lang.IllegalStateException - if no suitable persistence units can be resolved for injection

resolveResource

java.lang.Object resolveResource(InjectionPoint injectionPoint,
                                 NamingContext namingContext)

Resolve the value for the given @Resource injection point

Parameters:

injectionPoint - the injection point metadata

namingContext - the pluggable Web Beans JNDI lookup facility

Returns:

an instance of the resource

Throws:

java.lang.IllegalArgumentException - if the injection point is not annotated with @Resource, or, if the injection point is a method that doesn't follow JavaBean conventions

java.lang.IllegalStateException - if no resource can be resolved for injection

getEJBAnnotation

java.lang.Class<? extends java.lang.annotation.Annotation> getEJBAnnotation()

getPersistenceContextAnnotation

java.lang.Class<? extends java.lang.annotation.Annotation> getPersistenceContextAnnotation()

Get the annotation which defines a @PersistenceContext injection point

Returns:

the annotation which defines a @PersistenceContext injection point

getResourceAnnotation

java.lang.Class<? extends java.lang.annotation.Annotation> getResourceAnnotation()
