/**
 * Concrete AspectJ transaction aspect using Spring Transactional annotation
 * for JDK 1.5+.
 * 
 * <p>When using this aspect, you must annotate the implementation class
 * (and/or methods within that class), <i>not the interface (if any) that
 * the class implements. AspectJ follows Java's rule that annotations on 
 * interfaces are <i>not inherited.
 *
 * <p>A @Transactional annotation on a class specifies the default transaction
 * semantics for the execution of any <b>public operation in the class.
 *
 * <p>A @Transactional annotation on a method within the class overrides the
 * default transaction semantics given by the class annotation (if present). 
 * Any method may be annotated (regardless of visibility).
 * Annotating non-public methods directly is the only way
 * to get transaction demarcation for the execution of such operations.
