<td height="18"><b><a href="ProductViewAction.do?action=productDetail&productID=<%=item.getSubCategoryID()%>"><%=item.getSubject()%></a></b></td>

<td bgcolor="cccccc"></td>

<logic:iterate id="product" name="item" property="products" type="com.hjc.jbar.product.Product">
<tr>
<td>
<font size="-2" face="arial">
<%=product.getSubject()%>
</font>
</td>
<td></td>
</tr>
</logic:iterate>
<tr> </tr>
</table>
</logic:iterate>
</td>
</tr>
</table>
</body>
</html>

注意,在Hibernate配置XML中,把LAZY設定為FLASE,清單如下:

<class name="com.hjc.jbar.product.SubCategory" table="subCategory" dynamic-update="true">
<id name="subCategoryID" column="subCategoryID">
<generator class="identity"/>
</id>
<property name="subject" length="80" not-null="true"/>
<property name="body" length="2147483647" not-null="true"/>
<property name="picURL" length="255" not-null="true"/>
<set name="products" cascade="delete" inverse="true" lazy="false">
<key column="subCategoryID"/>
<one-to-many class="com.hjc.jbar.product.Product"/>
</set>
<many-to-one name="mainCategory" column="mainCategoryID" cascade="all" not-null="true"/>
</class>
