I believe that you could put all your (propName, value) pairs into a Map
object then call
BeanUtils.populate(destObject, srcMap);
or you could do
for(int i=0; i<attrSubString.length; ++i) {
BeanUtils.setProperty(destObject, attrSubString[i], data[i]);
}
BTW, when posting to commons-user, please put the name of the component
you are discussing in the subject line (as this reply does).
