HOW TO pass List of objects(a DTO) as single IN parameter to Stored Procedure

[chaithanya ibatis]

HI,
I've been working with Oracle DB and iBatis
Can anyone tell me how to passList of objects(a DTO) as single IN parameter to Stored Procedure using iBatis
for example
java.util.List  list = new ArrayList();
SampleDTO obj1 = new SampleDTO();
SampleDTO obj2 = new SampleDTO();
list add(obj1);
list add(obj2);

i want to pass this list object as an IN parameter to procedure.
(mapping required in SQL map files of ibatis)
or any resources on this or code snippet

thanks,
Chaithanya
