problem using anonymous fields...
Folks,
Why
java.org.apache.ojb.broker.accesslayer.JdbcAccessImpl.materializeObject(Clas
sDescriptor cld, Identity oid) doesn't resolve references?
Here is a javadoc excerpt:
/**
* performs a primary key lookup operation against RDBMS and
materializes
* an object from the resulting row. Only skalar attributes are filled
from
* the row, references are not resolved.
* @param oid contains the primary key info.
* @param cld ClassDescriptor providing mapping information.
* @return the materialized object, null if no matching row was found or
if
* any error occured.
*/
public Object materializeObject(ClassDescriptor cld, Identity oid)
throws PersistenceBrokerException
{
It created problems when I am using anonymous fields.
retVal = broker.getObjectByQuery(
new QueryByIdentity(example));
returns null, but the record exists!
Is there any workaround to keep using anonymous keys and be able to find
object by example?
Here is a class I am testing :
class-descriptor class=beans.Tracking table=SDRTII
field-descriptor name=diverseSuppNum column=DIVSUP#
jdbc-type=DECIMAL primarykey=true access=anonymous /
field-descriptor name=amount column=AMOUNT jdbc-type=DECIMAL /
reference-descriptor name=diverseSupplier
class-ref=beans.DiverseSupplier
foreignkey field-ref=diverseSuppNum /
/reference-descriptor
/class-descriptor
Thank you,

JDO and associations (1:n, m:n)
Hi there, I am trying to make a miniframework with OJB, based on its JDO plugin, so has to have business classes being persistent (almost transparently) and having a small application letting the user play with those persistent classes while viewing the state of the DB. (To be clear I try to have a very simple code for pedagogical purpose : this is like tutorial5 except that the class isn't Product but a set of classes generated from an UML diagram). All the basical operations work well but one : I can list, delete, insert objects but I cannot edit them... More precisely I can't edit them when they have references to other persistent objects. How do I proceed to edit one object ? I tried many ways :) First, my idea was to ask the user the id of the object (or everything which let me identify the one he wants), to get it from the database, and to modify a copy of it. Then when this is done, I begin a transaction, copy all the fields from the up-to-date copy to the original persistent instance (even the unmodified fiels) and commit. The problem is : the instance itself is updated correctly but the references are attempted to be reinserted automatically (even if unmodified) causing the database to reject it. As a matter of fact, those references have already been inserted so inserted them again is impossible : they share the same primary key (id). The second idea was to simply delete and then insert the copy after giving it the id of the deleted object. Here I got a JDOUserException for trying to insert an object with a key that already exist in the Persistence Manager cache... (does it means that JDO has got its own cache ? is this cache unable to see that the object was deleted just before ?) Then, I tried the tutorial-like way : that is to say to begin a transaction, get the object after getting the id from the user, let the user do what he wants with its fields and commit. This time, I got the same error as in the first procedure but quicker (so, is it a progress ? ;) ) : in fact, when I reach the commit, the first thing that happen is that my persistent layer wants to insert the references that my instance has, but as ever, because they already are in the datastore, it is impossible... So what ? Give up with editing what I stored and simply show how to insert and delete ? :) Thank you in advance. -- Hubert - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Do I need to create reference objects when storing object?
Please help! In the previous versions of OJB it wasnt necessary to create reference object when storing object that has reference but when I try the same thing with OJB 1.0 RC5 the FK fields are set by OJB to null. Is creating the reference object the right thing to do or is there some way to disable this ojb functionality?

Nested primitive types
I've got the following problem, that i can solve with a custom
implementation of PersistentField.
I've got a simple the following objects:
class A {
int i;
}
class B {
A a;
}
I store B and A in the same table using nested fields.
The problem is that when i store an empty B object (with the 'a' field to
null), a null is inserted into the column 'i'. That is fine, but when i read
it, the AbstractPersistentField::setNestedObject creates an A object before
setting not setting the null value to the 'i' field.
So the next time the B object is stored, the 'a' field is not null anymore,
and a 0 is inserted in the column 'i'.
Can the test that is made to skip the storing of a primitive value if the
object value is null can be made earlier so that the nested object is
accessed (and created) only if necessary ?

Pbm on MtoNCollectionPrefetcher
Hello There is a problem on the MtoNCollectionPrefetcher . Description : Input a MtoN relation in an Oracle database All the ids are SQL NUMBER and are declared as BIGINT in the repository.xml. The problem is that the Prefetecher use a ReportQuery in the method prefetchRelationship but use the class descriptor ( in the associateBatched method ) for generating identity . Identity on Object A using the ReportQuery : 2 BigInteger ( using the JdbcTypesHelper and the MetaDatas of the statement ) Identity on Object A using the ClassDescriptor : 2 Long The equal method of the identity return false even with the same ids ... So access to the maps childMap and ownerIdsToLists ( in associateBatched ) cause NPE because returning null values .

Re: Pbm on MtoNCollectionPrefetcher
Hello Thierry, Here is comment of Jakob Braeuchi in OJB-DEV on the same issue : http://article.gmane.org/gmane.comp.jakarta.ojb.devel/5084 - Original Message - From: Thierry Hanot [EMAIL PROTECTED] To: 'OJB Users List' [EMAIL PROTECTED] Sent: Thursday, January 22, 2004 3:31 PM Subject: Pbm on MtoNCollectionPrefetcher Hello There is a problem on the MtoNCollectionPrefetcher . Description : Input a MtoN relation in an Oracle database All the ids are SQL NUMBER and are declared as BIGINT in the repository.xml. The problem is that the Prefetecher use a ReportQuery in the method prefetchRelationship but use the class descriptor ( in the associateBatched method ) for generating identity . Identity on Object A using the ReportQuery : 2 BigInteger ( using the JdbcTypesHelper and the MetaDatas of the statement ) Identity on Object A using the ClassDescriptor : 2 Long The equal method of the identity return false even with the same ids ... So access to the maps childMap and ownerIdsToLists ( in associateBatched ) cause NPE because returning null values . I think may be the mapping of the good type of the ReportQuery result is missing ???

Oracle application server (Orion server) is our choice. I wonder if you have some examples I deploy an OJB application on Orion server. I really get confused on the configuration.

Hi, Armin
Thank you very much for the fixing. But I have one
more question. If the batch mode is turned on by
calling
broker.getConnectionManager().setBatchMode(true),
db
operations will not be applied to
db until transaction is commited. In this case, I
will
still have the problem if I want to insert two
records
in a batch and then retrieve them back right away
without committing the transaction.
This looks
differen from JDBC. After
PreparedStatement.executeBatch, even the
transaction
is not commited, I believe I can still retrieve
them
back. Is there any paticular reason for the OJB
batch
mode implementation?
Works in the same way as pur JDBC. You have to call
PB.serviceConnectionManager.executeBatch()
to execute the batch without committing the tx.

Armin

Hi Zhe,
I add your test case to test suite and fix the
problem in CVS head. It
will be included in upcoming 1.0.
You can easy fix it by changing one line in
ConnectionManagerImpl - see
below.
Thank you very much for test case and detailed
description.
