I have CMP (CatProdotto, CatprodottoHome, CatProdottoBean) entity bean that corresponds to the following table Cathegory:
id
name
description
parent_cathegory (that references id)
I have written the following recursive function:
private void removeChildren(Long parentId) throws Exception {
Collection children = ((CatProdottoHome) _entityContext.getEJBHome()).findByCathegory(parentId);
System.out.print("\nGot " + children.size() + " children of " + parentId);
Iterator childrenIt = children.iterator();
while(childrenIt.hasNext()){
CatProdotto child = (CatProdotto) PortableRemoteObject.
narrow(childrenIt.next(), CatProdotto.class);
removeChildren(child.getId());
child.remove();
}
}
In the database I have the following tree:
id=7 parent of id=9 parent of id=11 that has no children.
The function executes wright until it finds id=11, than
after calling removeChildren(11) (it dos'nt anything, because 11 has no childre) I call child.remove().
At this point I get the exception:
Got 0 children of 11
[Default]
Removing 11
[CatProdottoBean] TRANSACTION ROLLBACK EXCEPTION:Load failed; nested exception i

and os on..............
It seems that container call ejbLoad after remove().
Is this true ? Can I avoid it, it was fixed or teher are workarounds ?
Thank in advance to anyone helping me
Ciao Francesco
