[legolas wood]

Hi
Thank you for reading my post
I sa that connection object just has rollback method which accepts a 
savepoint object.
is there any way to create a savepoint object by having savepoint name?
or rollbacking to savepoint by having savepoint name?

another question:
Can we store some savepoint Object in a hashmap and then rollback to 
those savepoint ?
