I'm currently using:

Will BeanUtils.copyProperties do this same thing?

Thanks,

Matt

Pretty much, except:

* BeanUtils.copyProperties() does a shallow copy -- it does not
  recursively call itself on nested beans.

* BeanUtils.copyProperties() currently has a restriction that it doesn't
  deal with indexed and mapped properties that *only* have indexed and
  mapped getters/setters.  These are marked FIXME in the JavaDocs.  It
  works fine if you have getters/setters for the array/List or Map.

Things that BeanUtils.copyProperties() already does that might be of
interest include:

* Supports primitive properties.

* The origin or destination bean (or both) can be a standard JavaBean
  or a DynaBean.

* Conversions not restricted to String->Object, although that is the
  most common case for Struts users.

* Extensible conversions (register a Converter for your destination
  data type with ConvertUtils.register() and it will automatically
  get used).
