Hibernate呼叫oracle存储过程,遇到Mapping问题

用hibernate 呼叫oracle的存储过程,返回的结果集需要映射到一个pojo..
返回游标中的数据是从view中来的,请问能不能映射.

Alarm.hbm.xml

     {call I3.ALARM_PKG.getAlarmList(?, :networkCd, :elementId, :fromDate, :toDate, :pop, :ticketNumber) }

我发布的时候tomcat报错 rg.hibernate.MappingException: Unknown entity: com.tnzi.fmo.alarm.domain.AlarmVo

请各位大大指点..
