使用返回对象类型的java调用存储过程

Question

我从java调用存储过程。哪个返回参数是对象类型。

对象类型：

create or replace TYPE xx_hr_leave_record as OBJECT
(

  employee_name varchar2 (250),
  employee_number varchar2(10),
  Organization varchar2(250)      
);

程序：

  PROCEDURE GetLeaveInfo(p_notification_id IN NUMBER,
                         p_leave_detail OUT NOCOPY xx_hr_leave_record,
                         p_result OUT NOCOPY NUMBER,
                         p_error_code OUT NOCOPY NUMBER,
                         p_error_msg OUT NOCOPY VARCHAR2);

我使用pl / sql调用此过程，返回正确的输出。

但是我在以下链接的帮助下调用上述程序
