应该怎么去做？

一个javabean文件名为AdrReport.java 有以下几个属性，等等：
private String reportNo;                             // 报表系统编号
private Set report_adrname = new HashSet();          //adr名称
private Set report_adrmeddetail = new HashSet();     //药物商品名称主要是这两个report_adrname、report_adrmeddetail 放到了set集合里面，如何去取出这两个名称字段的值？
hibernate的映射文件：AdrReport.hbm.xml（report_adrname，report_adrmeddetail 这两个名称字段都是一对多的关系），是这样配置的：
        
        <set name="report_adrname" cascade="all" inverse="true" fetch="select" lazy="false">
          <key>
        <column name="reportNo"/>
          </key>
        <one-to-many class="com.adr.report.approvemanage.bean.ReportName"/>
       </set>
       
        <set name="report_adrmeddetail" cascade="all" inverse="true" fetch="select" lazy="false">
          <key>
        <column name="reportNo"/>
          </key>
        <one-to-many class="com.adr.report.approvemanage.bean.AdrMedDetail"/>
       </set>关联了三张表分别是：adr报表（adrReport表）、adr名称表（ReportName表）、药物明细表（adrMedDetail表）在页面上要显示的就是：adr名称、药物名称、报告日期等需要显示的字段信息
我应该如何将它们进行关联起来，在页面上输出，我用了logic:iterate 标签进行输出，页面上我是这样写的，但它报错了，不知道该怎么去写？？？<table border=1 cellspacing=0 borderColor=#FFFFFF
bgcolor="#EFEFED" rules=all style=" WIDTH: 100%; ">
<tr>
<td class="mail_tabletitle" height="24">报告编号</td>
<td class="mail_tabletitle">药物名称</td>
<td class="mail_tabletitle">不良反应名称</td>
        <td class="mail_tabletitle">不良反应结果</td>
<td class="mail_tabletitle">报告单位</td>
<td class="mail_tabletitle">报告日期</td>
<td class="mail_tabletitle">接收时间</td>
</tr>
<tbody>
<logic:present scope="request" name="adrmeddetailist">
<logic:iterate id="listrow" name="adrmeddetailist">
<tr onMouseOver="javascript:this.bgColor='#DEE2E3';"
   onclick="javascript:if(this.bgColor=='#DEE2E3'){this.bgColor='#F0F0E8'}else{this.bgColor='#DEE2E3';}"
   onmouseout="javascript:this.bgColor='#F0F0E8';"
   nowrap="nowrap">
<td width="15%" align="center" class="mail_tabletitle">
${listrow.reportNo}
</td>
<td align=center>
        <logic:iterate id="adrnames" name="listrow" property="report_adrname">

</logic:iterate>
</td>
<td align="center">
<logic:iterate id="medicationnames" name="listrow" property="report_adrmeddetail">
        ${medicationnames.report_adrmeddetail}
</logic:iterate>
</td>
<td align="center">
        ${listrow.result}
        </td>
<td align="center">
        ${listrow.orgName}

<td align="center">

        <td align="center">

        </td>
        <td align="center">

</td>
</logic:iterate>
</logic:present>

</table>这是要在页面上做显示的主要部分代码，但执行之后，报错了，报错的信息如下：HTTP Status 500 - --------------------------------------------------------------------------------type Exception reportmessage description The server encountered an internal error () that prevented it from fulfilling this request.exception javax.servlet.ServletException: Unable to find a value for "report_adrname" in object of class "com.adr.report.approvemanage.bean.ReportName" using operator "."
