iBatis报错

异常如下：
org.xml.sax.SAXParseException: The content of element type "resultMap" must match "(result*,discriminator?)".

源码如下：
[code="xml"]

<typeAlias alias="User" type="jp.co.grids.mda.entity.user.User"/>
<typeAlias alias="Department" type="jp.co.grids.mda.entity.user.Department"/>

<resultMap id="DepartmentResult" class="Department">
    <result property="id" column="ID" />
    <result property="depName" column="DEP_NAME" />
    <result property="users" column="ID" select="getUsers" />   
</resultMap>


<select id="getUsers" resultClass="User">   
    select * from users where id=#value#   
</select> 


<select id="Department.select" parameterClass="java.lang.Long" resultMap="DepartmentResult">
    select id, dep_name
    from department 
</select>

[/code]

框架是Spring2.5 + struts2 + ibatis2.3。 百思不得其解，语法应该没有错啊。
[b]问题补充：[/b]
yourgame 你贴的代码里并没有resultMap使用。

我贴一个给你参考 源代码工程可以下载
