Precompilers, OCI & OCCI :: Retrieve Collection Of User-defined Object?

I am having a OCCI problem, I try to retrieve a collection of user-define objects.

The major steps I am using are
1. define database object

CREATE OR REPLACE TYPE my_obj_t AS OBJECT
( id number, name varchar2(10) )
CREATE OR REPLACE
TYPE my_obj_tab_t as table of my_obj_t;

2. A stored procedure return a collection as out paramerter
my_stored_procedure(obj_list out my_obj_tab_t);

3. Using OTT to generate the *.cpp and header files.

4. Register out parameter like
vector<my_obj_t> vect;
stmt->registerOutParam(1, OCCIVECTOR,
sizeof (vect),
"MY_OBJ_TAB_T");

5. stmt->execute();

6. Try to get the results by
getVector(stmt, 1, vect);

I am getting compilation error:

Could not find a match for
oracle::occi::getVector(oracle::occi::Statement*,
int, std::vector<my_obj_t, std::allocator<my_obj_t>>).

Am I doing the right things ?What steps and function should I use ?
