Both of those should do fine from cuttings. That works well on pussy willow and forsynthia too. Don't know about oaks though. They sure do grow from buried acorns!
Anectdote: Last year the oaks were particularly prolific (I think they do that at times when the winter will be especially long) and I had so many in my driveway and walkway that it was dangerous. I kept almost falling down because them (long time since I roller skated
) so I saw to raking them up. I had such a huge pile that I hauled some to the leaf disposal area in the woods. I saved a whole big bin of them though thinking about holiday crafts but the snow flew while I was still trying to get overwintering plants in and I never felt like hauling the bin. I'd notice the level in the bin going down as I passed it whenever I took the dawg out and since it was a hard winter I was amused that I had inadvertantly provided the critters with a lunchenette. Overtime the bin was emptied of everything but scraps. Late spring I found little oak trees all over the place. If I make the squirrels a diner this year, it will be much closer to the woods.
