[common] convertUtils

I would like to copy a bean in an another bean with the same properties name
but some different type, using BeanUtils.copyProperties. ( in the common
package "org.apache.commons.beanutils")


I thought that conversions was possible but  i am not able to make them
work!

For example ...where is the mistake?

class BeanString {
String age;
...public void set...
...public String get..
}
class BeanInteger {
Integer age;
...public void set
...public Integer get..
}

then i do

BeanInteger intBean  = new...
BeanString stringBean = new...
PropertyUtils.copyProperties(intBean, stringBean);

and i get a NoSuchMethodException.
