具体的代码如下：
cargoExport为一个存放在request的ArrayList。
<logic:present name="cargoExport">
<logic:iterate id="cargo" name="cargoExport" type="ywsoftware.ship.businessTable.TCtcargo">
<logic:present name="cargo">
<bean:write name="cargo" property="shipper" />
//下边为显示javaBean里某个属性也是javaBean的显示格式
<bean:define id="tctcg" name="cargo" property="ctcg" type="ywsoftware.ship.businessTable.TCtcg"/>
<bean:write name="tctcg" property="marks" />
//下边为显示javaBean里某个属性是集合的显示格式
<logic:iterate id="loadct" name="cargo" property="loadCTs" type="ywsoftware.ship.businessTable.TLoadct">
<logic:present name="loadct">
<bean:write name="loadct" property="cntrNo" />
</logic:present>
</logic:iterate>
</logic:present>
</logic:iterate>
</logic:present>
--------------------------------------------------
//下边为显示集和里存放的是数组
<logic:iterate id="element" indexId="ind" name="catalog">
<bean:write name="ind"/>. <bean:write name="element" property="key"/><BR>
<logic:iterate id="elementValue" name="element" property="value" length="23" offset="0">
-----<bean:write name="elementValue"/><BR>
</logic:iterate>
</logic:iterate>
