对List进行循环遍历
<logic:iterate>标记也可以对List型的对象进行遍历，以下是一段示例代码。
<%
ArrayList list1 = new ArrayList();
list1.add("str1");
list1.add("str2");
list1.add("str3");
list1.add("str4");
list1.add("str5");
pageContext.setAttribute("testlist",list1);
%>
<logic:iterate id="showlist" name="testlist" indexId="index">
<bean:write name="index"/>:
<bean:write name="showlist"/>
</logic:iterate>

揭帖给分。谁来啊。
我就是靠这个文档实现logic:iterate的循环的
struts 标签 logic:iterate使用 logic:iterate
第一页 是struts官方的说明，
第二页 是个例子
第三页 是我实现的arrayList放入标签的方法。
这是页面文件
