I used a jack under the wing last night on my RV-8. We started to jack both wings but realized the cg was forward of the jacking points when the tail wheel started coming off the floor so we put some weight (carefully) on the horizontal stabilizer and jacked one side at a time. Worked fine, was very stable, and it allowed unencumbered access to the wheel.
As someone else implied earlier, the wings support the entire weight of the plane when we're flying and can support several times the planes weight when flying. Besides, Dicky V. says that the tie down mount is fine for jacking the plane. If he says it, it's probably true.

I should have elaborated when I posted my comments about the jack. I did post about using my wings for lifting each and every time I fly. I have absolutely no aversion to using wing jacks. The problem for me is I never really need to lift the whole plane but typically only a wheel. I don’t own any wing jacks and they are a bit more expensive than I want to pay. They also take up some extra room in the hangar. I have access to borrow them but it would take me longer to go transport them for use than to just use the little rig from Avery or one of the others as mentioned. I have seen methods for jacking with a floor jack and some blocking to the wing but that doesn’t appeal to me.
This is probably the main reason why many of us choose to use something other than wing jacks. If you have them available by all means use them. This is just my opinion however and I know there are others. Someone mentioned if something goes wrong and that is probably valid also. Any plane lifted regardless of the method needs to be secured. A wing jack is probably more secure than lifting the wheel with some form of pipe or avery rig. Make sure your plane is sufficiently choked.
If your plane is nose heavy when picked up by the jack points I would sure double check my weight and balance. I am not saying either way because I don’t know, but it would seem a little forward. Of course with a pilot in there it would be different. Were the tanks full?
