What is the correct statement to do orderBy in Oracle9i dev with EJB (CMP)?? I know this is possible with EJB (BMP).

thanks,

I am going to move this thread to a more appropriate forum, so that you can get answers quicker.

In EJB 2.0 CMP, you specify the query in ejb-jar.xml using EJB-QL. There is no ORDER BY in EJB-QL (yet - it is coming in EJB 2.1).
I know that Weblogic has an extention to EJB-QL that includes an ORDERBY keyword. Other appservers may do something similar, but I don't know.
If the ordering is important, you are stuck with BMP. Or you could do the ordering on the client using an appropriate Comparator with the Collection returned by the finder. Ugh.

Yes Dave is correct.
Order By is introduced in the EJB1.3
Chk the EJB 1.3 public draft
