AbstractResourceHandler

public abstract class AbstractResourceHandler extends AbstractHandler
This is an abstract class encapsulate generic behaviour of resource annotation. Concrete subclass handlers need to implement the following: public Class<? extends Annotation> getAnnotationType(); protected HandlerProcessingResult processAnnotation( AnnotationInfo ainfo, ResourceContainerContext[] rcContexts) throws AnnotationProcessorException; It may also need to override the following if other annotations need to be processed prior to given annotation: public Class<? extends Annotation>[] getTypeDependencies();

public com.sun.enterprise.deployment.annotation.HandlerProcessingResultprocessAnnotation(com.sun.enterprise.deployment.annotation.AnnotationInfo ainfo)

in the passed AnnotationInfo instance.
