I planted tomatoes from seeds in May. The plants have lots of blossoms, but there is only one green tomato on only one of the 7 plants. Is there something that I should do to stimulate the plants?
Hardiness Zone: 7a
Heat is one those factors. Once daytime temperatures reach into the 90's and nighttime temperatures hover near the mid 70's, tomato plants have trouble setting fruit because high temperatures render the pollen sterile. There are a couple of strategies to combat this problem.
The first is to grow varieties that mature earlier, before the Oklahoma summer heat sets in. Smaller tomato varieties (e.g. cherry) usually need less time to mature, while larger tomato varieties take longer. The smaller varieties are also more likely to set fruit better in hot weather.
You could also buy established seedlings or start yours indoors several weeks before transplanting in order to give them a jump on the season.
If your plants still haven't set fruit by the time the intense heat sets in, try to keep your plants healthy and consistently watered and once the temperatures drop, they should resume setting fruit.
Other factors that prevent tomatoes from setting fruit include low temperatures (below 50ºF), a lack of sunlight (less than 8-10 hours), inconsistent watering, damage from pests (e.g. thrips), or too much nitrogen fertilizer.
It gets extremely hot here in the summer, and tomatoes will flower, but not set fruit in the heat of our summers. My tomatoes are usually finished by the end of July or the first of August. If your plants survive our summer, about half of mine routinely die even though I set mine out early, water, and mulch them, they will flower and set tomatoes later in the season after it cools. These tomatoes won't quite be ready before our first freeze, but you can pick them green and allow them to ripen on their own.

I planted a cutting made from an Anna heritage tomato plant. The plant is loaded with blossoms, but no tomatoes.

Sorry if I do not understand your question but the fruits are not independant from the flowers. Tomato flowers become fruits just like strawberry flowers become strawberries. If your tomato plant is loaded with flowers you just have to wait. Just cut off the top of the plant to make it bushier.
Hope this help!
While it's true tomato flowers become fruit, they must first be pollinated. Do you spray your garden? If there are no bugs at all in the garden, your tomatoes won't be pollinated unless you do it by hand. My daughter hates bugs and has the same problem, which is wild considering I am an avid organic gardener. No pesticides in my garden. Good luck
I have very healthy looking tomato plants with plenty of flowers, but have yet too see any fruit. It is the middle of July and do not understand why my tomatoes are not producing any fruit yet. The plants are all very healthy looking. Does anyone have any ideas? Thanks
If you are having a hot summer, just be patient. Most varieties of tomatoes won't set fruit if the nights do not cool off enough. Keep the plants healthy, and once things cool off a bit, you will get fruit.

Could be lack of bees to pollinate plants.
