Interface EjbResolver

All Known Implementing Classes:

ForwardingEjbResolver

public interface EjbResolver

A container should implement this interface to allow the Web Beans RI to resolve EJBs, Resources and JPA persistence units TODO This probably needs renaming to EjbLifecycle

Method Detail

resolveEjb

java.lang.Object resolveEjb(javax.inject.manager.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(javax.inject.manager.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(javax.inject.manager.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()

the annotation which defines an @EJB injection point

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()

Get the annotation which defines a @Resource injection point

Returns:

the annotation which defines a @Resource injection point
