The approach I use involves overriding Resource.toRepresentation:
@Override public Representation toRepresentation(Object source, Variant
target) {
Representation rep = super.toRepresentation(source, target);
if (source instanceof HasLastModified) {
HasLastModified hlm = (HasLastModified) source;
rep.setModificationDate(hlm.getLastModified());
}
if (source instanceof HasEtag) {
HasEtag he = (HasEtag) source;
rep.setTag(he.gettag());
}
return rep;
}
