Norival, The XML parser is looking for a protocol for the DTD URI in the DOCTYPE declaration. I don't know how to do relative URIs in this context, so I've used absolute URIs like: file:///c:/obj/repository.dtd. No doubt there's a better way, but this will at least get you unstuck. Norival N

RE: newbie question

You should generally let the database set the OID for an object. If you load the object, the OID is set and therefore it will do an UPDATE when storing. If it's new, the OID is empty and therefore will do an INSERT. If you provide an OID for a new object (for example, get a value manually from a

generating DDL from repository.xml

I would like to generate the DDL from the class-definitions in repository.xml. I see that the unit tests that come with OJB use Torque to generate DDL. Is there a way to take the repository.xml and run it through Torque? It seems like a transformation might be in order to take the data from th

Hello all, I'm using the PB API and can store a simple object to a table. Even though table has a primary key constraint on the id column, if I try to store a different object with the same id, there is no primary key constraint violation. In fact, OJB _UPDATES_ the existing matching row in th

Re: IllegalStateException in DelegatingPersistenceBroker.getBroker

Hi Tom, do all odmg junit tests pass? Now OJB is more strict in handling PB instances. If PB.close() was called on a given instance no further method calls can be done. Your sample code seems ok, thus it sounds like a bug. regards, Armin - Original Message - From: "Thomas Dudziak" <[EMAI

Hi, I believe it is possible *only* if you do not use a primitive to hold the primary key. In order to assign primary keys, OJB need to know if an object needs a key. If the key is stored as an Object e.g. Long, Integer, BigInteger etc then it checks to see if the attribute is null. If, however,
