u need to create a stored procedure using in/out parameter
of a ref cursor.the parameter of the proc should be in only.
then create a connection to the database using middleware.
suppose u have created a proc on oracle 9i, then make the
connection using oracle client.mention the user
name/password and the data base name in the connection.
then in the report section use the stored procedure as data
provider and select the proc using which you want data ang
generate the report.

Deepak,
ur answer has helped me a lot.Thanx a tonne. Guys, pls
follow his steps for Creating report using SP:

1-Select Data---New Data Provider--Stored Procedure
2-Select or define the db connection
3-Choose the stored procedure
4-Specify stored procedure as the data source
5-Define parameters


Use REF CURSOR with IN/OUT parameter. 
Ref cursor is a cursor variable that points to any cursor,
mainly used for returning the CURSOR OUTPUT. 
Eg:

CREATE OR REPLACE PROCEDURE BO_proc(proc_cur IN OUT
sys_refcursor)
AS
BEGIN
OPEN proc_cur FOR SELECT * FROM EMP;
END;
