I got an example how to call oracle SP in iBATIS 3 without a map file.
And now I understand how to call it.
But I got another problem that how to get a result from output parameter(Oracle cursor).
A part of exception messages is "There is no setter for property named 'rs' in 'class java.lang.Class".
Below is my code. Does anyone can help me?

Oracle Stored Procedure:

CREATE OR REPLACE PROCEDURE getProducts
(
    rs OUT SYS_REFCURSOR
)
IS
BEGIN
    OPEN rs FOR
    SELECT * FROM Products;
END getProducts;

Interface:

public interface ProductMapper
{
    @Select("call getProducts(#{rs,mode=OUT,jdbcType=CURSOR})")
    @Options(statementType = StatementType.CALLABLE)
    List<Product> getProducts();
}

DAO:

public class ProductDAO
{
    public List<Product> getProducts()
    {
        return mapper.getProducts(); // mapper is ProductMapper
    }
}
