level limit for cascading

Hibernate version: 3.1

Name and version of the database you are using:PostgreSQL 7.4

my senario is

classA <1----*> classB<1----*>classC ..... till classX (all have 1--* relation)

if i go for a code like this for persisting the entire association
like

Code:

ClassA classA = new ClassA();
....
....
classA.setClassB(classB);
classB.setClassC(classC);
....
...
(classX-1).setClassX(classX);

session.save(classA);

assuming i've give cascade="save-update" in all association mapping .
1) upto which level i can make use of cascading . here i am saving only classA object , which results in cascaded save of the associations
2) same question i have , in loading of classA and traversing the chain .
say, i load classA first.

i need to call classA.getClassB().getClassC().......
is there a limit to this level

i dont know if such situations occur in real time . but confused about the matter

[/code]

No, there are no limits in either case. There are limits to eager loading (hibernate.max_fetch_depth), but not to lazy loading.
