hibernate 查询出的list不能转换成持久化类
新手，刚刚学习ssh2框架，登陆功能，这是我写在Dao类下的方法：
public UserClient findClient(String userName,String password){
String[] param =new String []{userName,password};
String sql="form UserClient as model where model.userName = ? and model.password = ? ";
List<UserClient> list=(List<UserClient>)getHibernateTemplate().find(sql,param);
if(list != null && list.size()>0)
{
return (UserClient)list[0]; //这里报错！！！ 
}
else
return null;
}
但是list[0]这里报错，
说The type of the expression must be an array type but it resolved to List<UserClient>
UserClient是持久化类，我用Myeclipse的hibernate reverse engineering 自动生成的

------解决方案--------------------
list.get(0)
