Subject Re: insert/update objects graph

If I understand your question correctly, you want to take (for
example) an Order object with a list of OrderLine objects and insert
them by just saying this:

  sqlMap.insert("order.insert", myOrder);

If so, then no, this is not a part of iBATIS.

While that is a common ORM feature, iBATIS is not an ORM, it is a SQL
mapper - it maps objects to/from SQL, not objects to/from database

That said, doing what you are asking is still pretty simple - here's a
(non-transactional) example:

public insertOrder(Order order){
  // this assumes that the "order.insert" includes a selectKey element
  sqlMap.insert("order.insert", order);
  for(OrderLine ol:order.getOrderLines()){
    sqlMap.insert("orderline.insert", ol);

If you are using Spring, you add a transaction annotation, and ba-da-bing. Done.

For 4 lines of code, you have this instead:
