SampleDTO
{
String,
int
Date
Collection AnotherDTO
}

AnotherDTO
{
String,
int
Date
Collection YetAnotherDTO;
}

Now, Im looking for a method in Hibernate which can take in a Collection of SampleDTO objects & persist recursively all its children.

Im using Hib 2.1 & Ive heard this is only possible in Hibernate 3.0

Pl advise. if this possible?

Map you classes using cascade="all" in the one-to-many direction.
Iterate over your SampleDTO and save each one. The save will then cascade.

This is possible with Hib2 and 3

Using cascade all wont work fine I guess, atleast its a performance hit if you loop on the Collection & call a "save" for every object. (assuming its an SQL query execute behing the hibernate call)

Imagine 1000 records & this method can go for a major toss!

Thats precisely the reason why we are currently using stored procedures which takes in an ORacle ARRAY Type with STRUCT types built in (the types converted in DAO layer)

I had the impression that Hibernate is smart enuff to do a recursive save, but things look otherwise here :(
