Hi, Frank. I created a similar method, but rather a static one than a member method. So mine is in a class called BeanUtil (not the apache commons beanutils) and applicable to any other java bean. No need to modify the base class or whatever. So I can apply it on FormBeans as well as servletRequests or whatever may come, which suits me more for debugging.
