OJB 1.0.1 mapping associations(1:1,1:n) not working with Oracle8
Hi all, I tried to port an application from mysql to oracle 8. My problem is the same as described here: http://nagoya.apache.org/eyebrowse/[EMAIL PROTECTED]msgId=1643290 Assigned to the mapping associations i.e. I get a null value because the n-side objects (or single object for 1:1) are not materialized. the answer was, that is was fixed with 1.0 rc6 and Oracle9 but with oracle 8 and 1.0.1 the problem still occurs. (with mysql I also had no probs) Is there any way to solve this problem? I cannot switch to oracle 9, cause the app has to run on an existing DB server with oracle 8. Thanks for your answer!

Re: ODMG - delete referenced objects.
Dnia czwartek, 11 listopada 2004 13:49, Gerhard Grosse napisa: On Wed, 10 Nov 2004 21:26:22 +0100, Grzegorz Pypec [EMAIL PROTECTED] wrote: Instead of tx.checkpoint() you can use ((TransactionExt) tx).flush(), which flushes all SQL to the DB without commit. However, normally OJB does a pretty good job in ordering the SQL correctly. Could it be that you have some cyclic references in your object model (e.g. A-B and B-A)? Gerhard I suppose that after invoking flush(), transaction holds db connection opened all the time so we can later rollback? From JavaDoc: Calling flush flushes persistent object modifications made within the ODMG transaction since the last checkpoint to the underlying database transaction If so, it is not a good news :) Is anyone has similar problem with deleting referenced objects? I have exactly the same problem as Grzegorz Pypec with ojb1.0.1 nad PostgreSQL 7.4 (jdbc 3.0 drv). I can't believe that such essential feature doesn't work. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: Re: Simple Inheritance problem with multiple class to one table mapping
Hi,
Thank for your help, but I think I solved my problem.
I don't know what I was doing wrong, but simply by rewriting by hand the
Apartment Class, I solved the problem.
Now I works really great, despite sometimes Eclipse seems to go a little crazy,
so I think I also need to update it (ver 3.0.1).
Thx,
Sylvain.
