Re: Foreign key not set
Hi Jean-Yves,
in User the 1:n reference the auto-update setting is undefined and by
default OJB use 'link' for 1:n relations, thus I would expect that the
FK in Admin will be set.
Could you post the generated repository.xml for User, Admin, Role?

Hello,
I'am having trouble trying to find out what i am doing wrong, i have a
class user and a class role and a user has a collection of roles, this
kind of schema is working for other classes with the same kind of
relationship but not for this one.
OJB is trying to insert a null value in the column of the foreign key
id, but the role is in the collection of roles of the user instance.
I'am using latest CVS OJB, my two classes are :
public class User implements INamable {
/**
* @ojb.field primarykey=true
*/
private String id;
*/**
* @ojb.collection element-class-ref=org.jys.clepsydra.data.users.Role
* foreignkey=userId auto-delete=true
*/ private ListRole roles = new VectorRole();
*
/**
* @ojb.field
*/
private String url;
public User(String name) {
this.name = name;
}
public User() {
super();
}
/**
* @return Returns the roles.
*/
public ListRole getRoles() {
return roles;
}
/**
* @param role
* @throws DataIntegrityException
*/
public void addRole(final Role role) throws DataIntegrityException {
if (findRole(role.getDocumentBase()) != null) {
throw new DataIntegrityException(this + already has a role
for + role.getDocumentBase());
}
roles.add(role);
}
}
and
public abstract class Role implements IDataObject {
/**
* @ojb.field primarykey=true
*/
private String id;
/**
* @ojb.reference foreignkey=documentBaseId auto-update=none
auto-delete=none
*/
private DocumentBase documentBase;
public Role(DocumentBase base) {
super();
this.documentBase = base;
}
public Role() {
super();
}
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public DocumentBase getDocumentBase() {
return documentBase;
}
public boolean equals(Object object) {
if (object instanceof Role) {
return this.id.equals(((IDataObject) object).getId());
}
return false;
}
public String toString() {
return this.getClass() + + this.getDocumentBase();
}
}
and what i am trying to do is
Role admin = new Admin(getCurrentBase());
DataHelper.generateId(admin);
User t = getTestUser();
t.addRole(admin);
DataHelper.store(t);
If u have any clue about... Thank you.
Jean-Yves

I setup a similar test
Implementation odmg = OJB.getInstance();
Database db = odmg.newDatabase();
db.open(null, Database.OPEN_READ_WRITE);
BookShelf bookShelf = new BookShelf(prefix);
TransactionExt tx = (TransactionExt) odmg.newTransaction();
tx.begin();
db.makePersistent(bookShelf);
tx.commit();
tx.begin();
tx.lock(bookShelf, Transaction.WRITE);
BookShelfItem ev1 = new DVD(bookShelf);
BookShelfItem ev2 = new Book(bookShelf);
bookShelf.addItem(ev1);
bookShelf.addItem(ev2);
tx.commit();
works fine! BookSelf has a 1:n to abstract class BookSelfItem and the
test add a concrete objects to an existing BookSelf object. The FK is
defined as anonymous field in the abstract class:

Did you checked your test with a debugger? Is the PK of the User object
populated with non null value? I don't know what's going on in your
persistence layer, is User 't' locked before the admin is added?
But something like that will work too:
...
BookShelfItem ev1 = new DVD(bookShelf);
BookShelfItem ev2 = new Book(bookShelf);
bookShelf.addItem(ev1);
bookShelf.addItem(ev2);
tx.begin();
tx.lock(bookShelf, Transaction.READ);
db.makePersistent(ev1);
db.makePersistent(ev2);
tx.commit();
Could you setup a test only using the odmg-api which reproduce your problem?

Re: Foreign key not set
So i still don't get it, the workaround is to not use anonymous foreign
key and to set the userId myself...
As i don' t know in OJB where the anonymous key is supposed to be set i
can't really try to find the bug for now, but i'll try to take a look.
Thanks for your help.

Re: Foreign key not set
Hi again,
a correction of my previous post (I don't realized that you use the
odmg-api). In the new upcoming version you have to set
auto-update=none and auto-delete=none or object when using the
odmg-api.
collection-descriptor
name=roles
element-class-ref=org.jys.clepsydra.data.users.Role
auto-update=none
auto-delete=none or object
inverse-foreignkey field-ref=userId/
/collection-descriptor
regards,
Armin

i'am going to try to do it with a non abstract class maybe it can be that.

Re: Foreign key not set
I can not keep trying right now, but i will tomorrow, the visible
difference i see is that of storing the user i use the way :
Transaction tx = getImplementation().newTransaction();
tx.begin();
db.makePersistent(o);
tx.commit();
But the collections of roles is modified before that. Maybe i'am not
doing it the right way, but it's working for all my other similar
relations...
Are we supposed to lock the object before any modification are made to it ?
When i tried the way you did in the sample you give i get an exception
org.apache.ojb.odmg.TransactionAbortedExceptionOJB: Can't commit
objects: Unexpected behavior
java.lang.RuntimeException: Unexpected behavior
org.apache.ojb.odmg.ObjectEnvelopeTable.cascadeInsertSingleReferences(ObjectEnvelopeTable.java:602)

I setup a similar test
Implementation odmg = OJB.getInstance();
Database db = odmg.newDatabase();
db.open(null, Database.OPEN_READ_WRITE);
BookShelf bookShelf = new BookShelf(prefix);
TransactionExt tx = (TransactionExt) odmg.newTransaction();
tx.begin();
db.makePersistent(bookShelf);
tx.commit();
tx.begin();
tx.lock(bookShelf, Transaction.WRITE);
BookShelfItem ev1 = new DVD(bookShelf);
BookShelfItem ev2 = new Book(bookShelf);
bookShelf.addItem(ev1);
bookShelf.addItem(ev2);
tx.commit();
works fine! BookSelf has a 1:n to abstract class BookSelfItem and the
test add a concrete objects to an existing BookSelf object. The FK is
defined as anonymous field in the abstract class:
class-descriptor
class=org.apache.ojb.broker.CollectionTest$BookShelfItem

Did you checked your test with a debugger? Is the PK of the User
object populated with non null value? I don't know what's going on in
your persistence layer, is User 't' locked before the admin is added?
But something like that will work too:
...
BookShelfItem ev1 = new DVD(bookShelf);
BookShelfItem ev2 = new Book(bookShelf);
bookShelf.addItem(ev1);
bookShelf.addItem(ev2);
tx.begin();
tx.lock(bookShelf, Transaction.READ);
db.makePersistent(ev1);
db.makePersistent(ev2);
tx.commit();
Could you setup a test only using the odmg-api which reproduce your
problem?

Armin
