王垠的「40 行代码」

webwork action定义
ListGoods 为Map型
public String justFindGoodsItem() throws Exception{
List item1=goodsItemDao.justFindGoodsItem();
itemGoods.put("goodsItem",item1);
return SUCCESS;
}
从hibernate取出数据
public List justFindGoodsItem(){
List goodsitem=hibernateTemplate.find("from Goodsitem");
if(!goodsitem.isEmpty()){
return goodsitem;
}
return null;
}
在页面上先调用此action
然后<ww:select name="department" list="itemGoods"/>
出现错误如下：
org.apache.catalina.core.ApplicationContext log
信息: tag 'select', field 'list', name 'department': The requested list key 'itemGoods' could not be resolved as a collection/array/map/enumeration/iterator type. Example: people or people.{name}
恳请大家指点
