RE: RE : RE : BIGINT to Long, FieldConversion ?
You have to put the B instance. If there is a relation between the two classes in repository.xml you must use object instances. Otherwise you must use the class A field id attribute.

Thanks Ricardo ! I would like to know wich kind of link you do : Object A have a reference to B, called bB. If I want to insert in db A, Have to do : A.setbB(instanceB); Or A.setb_FK(id_B_PK); Should I set the bB instance or the FK_Id ?

Both, variable name and column name of the Bean/Table are named name.
Same code without upper() works (but doesn't produce any result, as
upper() is necessary):
...
if(collegiateName != null collegiateName.trim().length() 0){
crit.addLike(colegiate.name, % +
collegiateName.toUpperCase() + %);
}
If I rename the Bean var name to accountName:
...
if(collegiateName != null collegiateName.trim().length() 0){
crit.addLike(upper(colegiate.accountName), % +
collegiateName.toUpperCase() + %);
}
...
the code works fine.
Could it be a OBJ bug?

repository_user.xml, reverse-db and field indexes
I found than if list of field descriptors inside a class descriptor in repository_user.xml don't work properly if field indexes begin with 0 (as generated by reverse-db) and reference descriptors are defined for some fields. Key values were loaded right, but some associated beans are loaded and some not. This behavior was found for a table with 4 references to another table (4 types of users of class UserBean).

RE: repository_user.xml, reverse-db and field indexes
New information: Field descriptor indexes can begin with 0 (there's no complaints) but if I put a reference-descriptor with a foreign-key id = 6, OJB gets the bean for the previous field-id (as it starts counting with 1).

By dynamicly I mean in Java code. Say in the xml file there is the default version, but in Java code I'd like to change value for one shot. Note that I don't want to modify the xml file. is org.apache.ojb.broker.metadata a way to a solution ? I was able by this way to obtain value store in the repository xml file, but is it possible to change values (any values ?) without writing to the file ?

I was wondering if there was a method by which I could set auto-update, retrieve and delete from within my java code. I don't want to put it in the xml because sometimes when I select say a Home, I only want to have the home info, but I don't want to cascade my search. Sometimes when I delete an object there are instances where it's OK to cascade delete, others when it's not. Same goes with update. Thanks R -- Robert S.

RE: OJB Setup
You could use
broker = PersistenceBrokerFactory.defaultPersistenceBroker();
if you only want to connect from the default connection (and if you
only has one connection configured).

Asunto: OJB Setup
Hi All,
While trying to setup ObJectRelationalBridge, I created a test project and
copied all necesary files from the example in test1. Everything was very
clear. Then I copied code from tutorial 1:
try
{
broker = PersistenceBrokerFactory.
createPersistenceBroker(new PBKey(repository.xml));
}
This failed over and over again. After half a day I started reading the
code. In PBKey.java it came to my attention that the filename
repository.xml is not the parameter expected. Instead it seems that it
should be the name of the jdbc connection (jcd-alias). Am i right here?
regards,
Lennart
