Data Transfer to Action Beanpublic synchronized void fillResearcher(Object bean, String researcherId)

Map m = describe(source); for (Object o : m.keySet()) { if (m.get(o) instanceof List) { List l = (List) m.get(o).getClass().newInstance(); l.addAll((List) m.get(o)); m.put(o, l); } } populate(dest, m);

1. Simply pass in bean2. fillResearcher will find a data fields with similar names3. Fill them with data
