Preheat oven to 325°F. Line your roasting pan completely with foil.
Unwrap your ham and discard any glaze packets that came along with it. Remove the plastic 'plug', if there is one.
Place your ham cut or flat side down, on the rack. Cover with foil.
Bake the ham for one hour. Remove the pan from the oven and remove the foil. Add the pineapple rings around the base of the ham. Pour the pineapple juice over the ham and pineapples. Bake, uncovered, for one more hour.
At this point you can raise the oven temperature to 425F and brush a thick layer of glaze over the whole surface of the ham. Let some of the glaze drip down over the pineapples. Put back into the oven and continue to cook for another 15 -20 minutes or so. Baste with another layer of glaze during this baking time. Your ham should have an internal temperature of 140F.
Transfer the ham and pineapples to a platter. Shift the ham so it is sitting back on its side so you can easily remove the slices. I glaze the ham with any leftover glaze before serving.
