An aspect is a class containing one or more advice methods, which must have the signature public Object <any-name>(Invocation inv) throws Throwable The invocation argument must be of type org.jboss.aop.joinpoint.Invocation, or one of its subclasses. An interceptor is a special type of aspect, and implements the org.jboss.aop.advice.Interceptor interface, which effectively forces you to create an aspect with one advice method.
