Yes, feel free to add it wherever :)

There are situations when an application has no "direct" access to the database 
(no SELECT / UPDATE / INSERT / DELETE statements allowed), and it can use only 
stored procedures for data access. In order to be able to use OJB in such 
situations, OJB should always use stored procedure calls. For example, 
currently, if stored procedure for retrieval by fk is set, batch retrieval is 
turned off (because it uses SELECT ... WHERE ID IN (1, 2, ...) statement which 
is not trivial to do with stored procedures). So at the cost of some slowdown, 
it's possible to use OJB when "direct" database access is not allowed.

I can suggest two ways of making it work with stored procedures:

   * Use selectByPkStatement if stored procedure is configured,
     similar to getPreparedSelectStatement:
