Drain oranges and pineapple, reserving juice; add enough water to juice to measure 1/2 cup. Set fruit aside.
Bring 3/4 cup water to a boil in a saucepan. Add gelatin; cook, stirring constantly, 2 minutes or until gelatin dissolves. Remove from heat, and stir in juice mixture. Cover and chill mixture until mixture is the consistency of unbeaten egg whites. Fold in oranges, pineapple, whole-berry cranberry sauce and pecans. Gently fold in blackberries.
Lightly spray a 6 cup mold with non-stick cooking spray. Spoon fruit/jello mixture into mold.
