SQL & PL/SQL :: Writing Procedure In User 2 Schema Accessing Table Product - Not Compiled?

I have got 2 users as user1 and user2.I have used the following statements from user 'user1':

create role GENEVAOBJECTS;
grant select, insert, update, delete on PRODUCT to GENEVAOBJECTS;
grant GENEVAOBJECTS to user2;

In the above statements, product is a table. Now, I could able to access this table from user 'user2'. But however if I write a procedure in user2 schema accessing the table product, then the procedure is not getting compiled.

create or replace procedure test_prc as
v_test number(9);
begin
select product_id into v_test
from PRODUCT where rownum=1;

[code]...

why I cannot access that table from procedure?
