Problem about access values stored in xdata

Dear sir,i use uVision IDE for 8051 ver 6.20c. I used AT89C81. My problem is, i want to store 25 integer value in an array called melody. When i tried to write code in following way, i get error "adress space overflow".
-############################

int rit[] = {6, 12, 12, 6, 12, 24, 24, 18, 18, 18, 12, 12, 6, 12, 8, 8, 8, 12, 6, 12, 12, 6};

-############################
Then i used XDATA memory to save my integer values. In order to do that i wrote following code segment instead of previous one.
-############################

unsigned long int xdata rit[25] = {6, 12, 12, 6, 12, 24, 24, 18, 18, 18,12, 12, 6, 12, 8, 8, 8, 12, 6, 12,12, 6, 6, 6, 12};

-############################

Compiler seems happy because i got no error*1, moreover as far as i understand those values is stored in XDATA memory.However, when 8051 try to access those value, simulation does not works fine because 8051 could not get those values which is stored in XDATA.

The code below shows how i try to get those integer values.

-############################
int i; for ( i=0; i<24; i++) { int tempo = rit[i];
-############################

Any help would be appreciated.
