Action beans should/must be "prototype" scope ?

Spring provides a utility method to load a Class from a class name :

 Class<?> beanClass = ClassUtils.resolveClassName(beanClassName,
ClassUtils.getDefaultClassLoader());

Another Spring utility method traverses the inheritance tree looking
for an annotation :

 Scope scope = AnnotationUtils.findAnnotation(beanClass, Scope.class);
