The cloning code in beanutils is for cloning JavaBeans (or objects that "look like" JavaBeans). This serialization cloning method doesn't place that restriction. It only requires that the object be serializable. I think this code is general enough to live in Commons Lang.

If BeanUtils already has cloning code, and so does SerializationUtils, why would write yet another class? --- Stephen Colebourne <[EMAIL PROTECTED]> wrote: > Have a look in SerializationUtils.
