I wrote this method to achieve : it can perfectible i think.
public static void copyProperties(Object pojo, DynaBean bean)
throws IllegalAccessException,
InvocationTargetException,
ClassNotFoundException, InstantiationException {
DynaProperty[] dynaProperties =
bean.getDynaClass().getDynaProperties();
for (DynaProperty d : dynaProperties) {
Object value = bean.get(d.getName());
Class type = d.getType();
Class c;
if (d.isIndexed())
c = type.getComponentType();
else
c = type;
// c'est un dynaBean
if (DynaBean.class.isAssignableFrom(c)) {
String pojoName =
c.getName().replaceFirst("Lazy", "dao.Pojo");
if (d.getType().isArray()) {
Object[] objs = (Object[])
Array.newInstance(Class.forName(pojoName),Array.getLength(value));
for(int i =0 ; i<objs.length;i++){
objs[i] =
Class.forName(pojoName).newInstance();
copyProperties(objs[i],
(DynaBean) Array.get(value,i));
}
BeanUtils.copyProperty(pojo,
d.getName(), objs);
} else {
Object in =
Class.forName(pojoName).newInstance();
copyProperties(in, (DynaBean) value);
BeanUtils.copyProperty(pojo,
d.getName(), in);
}
// copie simple
} else {
BeanUtils.copyProperty(pojo, d.getName(),
value);
}
}
}
