c标签的迭代方法：
<select name="orderType"id="orderType" style="100%;"><!--onchange="clickSelectFlow();" -->
<c:forEach var="processConfig"items="${processInfoList}" >
<option <c:if test="cmbFlow==${processConfig.chileEle_DefineID}">selected</c:if> value="${processConfig.chileEle_DefineID}" style="tableName:${processConfig.chileEle_Table}">${processConfig.chileEle_DefineName}
</option>
</c:forEach>
</select>
s:iterator 标签有3个属性：
value：被迭代的集合
id ：指定集合里面的元素的id
status 迭代元素的索引
你可以用status（迭代元素的索引）来判断 #status.index == 3
2:索引的用法
如果指定了status，每次的迭代数据都有IteratorStatus的实例，它有以下几个方法
int getCount()返回当前迭代了几个元素
int getIndex()返回当前元素索引
boolean isEven()当然的索引是否偶数
boolean isFirst()当前是否第一个元素
boolean isLast()
boolean isOdd()当前元素索引是否奇数
<s:iterator value="{'a','b','c'}" id='char' status='st'>
<s:if test="#st.Even">
现在的索引是奇数为:<s:property value='#st.index'/>
</s:if>
当前元素值：<s:property value='char'/>
</s:iterator>
如果从你的Action中返回的是list,可采用如下方式：
<s:iterator id="obj" value="list"status="status">
<s:if test="#status.index == 3">
<s:set name="j" value="0"></s:set>
</s:if>
<s:property value="obj"/><br>
</s:iterator>
