Bring the salted water to a boil. Add the rice, cover and simmer over low heat for 12 to 15 minutes or until just done. Immediately drain the rice when tender, rinse under cold water to stop the cooking process and drain again. Pat dry and set aside until later.
In the bottom of a mixing bowl stir together the olive oil, lime juice, cumin, salt and jalapeno peppers. Add the rice to the dressing along with corn, bell peppers and olives; adjust the seasoning.
In a separate mixing bowl combine the tomatoes with the shrimp and cilantro.
On each dinner plate arrange a bed of lettuce. Center rice and corn salad over the top. Place the shrimp in the center and garnish with black olives.
