Hello Armin, this is really costing my nerves!!
Same result as before! It is passing by without an exception and with no result! And as I sad, before I try to delete I'm looking up the object in the database (with findByPrimaryKey) to be sure I delete an existing object: ServerVO toBeDeleted = findByPrimaryKey(integrationVO.getEntryId(), new Locale(integrationVO.getLocale())); Transaction tx = odmg.newTransaction(); tx.begin(); odmg.currentTransaction(); db.deletePersistent(toBeDeleted); tx.commit(); Can it be because of the structure of my Objects/Repository? ServerVO has some simple attributes and a reference to ModulesVO (1:1). ModulesVO holds a List (1:n) of Objects extending the class ModuleVO. But I would expect to see at least anything like an SQL or at least a warning, if I try to delete an Object that has references on other Objects. Or not? I attach an ER-Diagramm of my structure to get an understanding of what I'm talking about. Because I fear it's a little bit confusing. But I'm not sure if it could have to do something with it.

Does the 'toBeDeteted' object really exists in the database? OK, another attempt let OJB do the whole tx demarcation. Use OJBTxManagerClass=org.apache.ojb.odmg.LocalTxManager ConnectionFactoryClass=org.apache.ojb.broker.accesslayer.ConnectionFacto ryPooledImpl Transaction tx = odmg.newTransaction(); tx.begin(); db.deletePersistent(toBeDeleted); tx.commit() Does this works for you? regards, Armin ----- Original Message ----- From: <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Thursday, July 10, 2003 9:09 AM Subject: AW: transaction in JBoss with MySQL Datasource The result is, that I get no exception but also no result! It simply passes by with no SQL being executed. I integrated P6Spy for debugging of the SQL and it also shows no statement being mad (no delete or so). Anything else to try? It seems to me, I've tried already all combinations. Julia. -----Ursprüngliche Nachricht----- Von: Armin Waibel [mailto:[EMAIL PROTECTED] Gesendet: Mittwoch, 9.
