项目用的是ＨＩＢＥＲＮＡＴＥ＋ＰＲＯＸＯＯＬ，请大家帮帮忙，我都不知道这问题出错在什么程序中＾

说说自己的感受: 
  此问题,应该出自在AdminloginAction 调用AdminuserDAO 的 findByProperty方法中!是一个简单的登陆查询用户信息的DAO,由ECLIPSE自动生成的DAO,我也看过了并没有什么发现 
public List findByProperty(String propertyName, Object value) { 
log.debug("finding Adminuser instance with property: " + propertyName 
+ ", value: " + value); 
try { 
String queryString = "from Adminuser as model where model." 
+ propertyName + "= ?";
