Preheat oven to 375 degrees.
In a large bowl, cream butter and sugar together with an electric mixer until fluffy.
Add eggs, one at a time, mixing well after each addition. Blend in vanilla.
In a separate bowl combine flour, salt, and baking soda. Add to butter/sugar mixture and stir until combined.
Spread dough onto a lightly greased jelly roll pan. Bake for about 10 minutes, until light golden brown. Do not overbake. Cool completely.
Meanwhile, prepare the cream cheese layer by beating the cream cheese and powdered sugar with an electric mixer until smooth. Stir in the vanilla. Add the cream gradually until frosting reaches desired consistency for spreading.
In a medium saucepan, whisk together the jam and 2 tablespoons of water. Heat over medium heat, stirring frequently, until jam mixture is smooth. Add more water as needed. Cool completely.
Spread the cream cheese mixture over the cooled crust. Arrange the fruit over the cream cheese. Brush the fruit with the cooled jam mixture to glaze. Refrigerate until ready to serve.
