JSP+IBATIS出现的难以解答的问题！！求助！！
我是想在一个页面当中显示某数据表的所有信息页面相关代码如下：

<%
try{
SqlMapClient sql = new MySqlMapClient().getSqlMapInstance();
request.setAttribute("list",sql.queryForObject("list",null));
List<Login1> list = (List<Login1>)request.getAttribute("list");
for(int i = 0; i<list.size();i++){
System.out.println(list.get(i));
}
} catch (SQLException e) {
e.printStackTrace();
}
%>

数据库持久层使用ibatis框架。
但是当页面启动的时候报错误：

java.sql.SQLException: Error: executeQueryForObject returned too many results.

请问这个问题是怎么回事？应该如何修改？

------解决方案--------------------
你的方法错了 
如果你的返回值是list类型 方法是queryForList()
返回值是object类型 方法才是queryForObject()
