Cannot connect to Oracle via SSRS Report Server

I can run my SSRS report (which accesses  2 Oracle tables) from my PC.
When I load .rdl to Report Server the report will not run and I get this error:

An error has occurred during report processing.
Cannot create a connection to data source 'sds_getpaid'.
ORA-12154: TNS:could not resolve service name

Dba's verified that the correct info is in the tnsnames.ora table on the report server.

yes, I connect to Oracle tables in a sql 2005 stored procedure that is accessed  by a SSRS report.
