参考：The tag then loops over each member of the collection (which can either be an array, a Collection, Enumeration, Iterator, or Map), setting the id to the element and evaluating its contents.
1) session.setAttribute("list", list);在jsp的<html:form>对应的action中设置.在action的execute里设置session.setAttribute("list", list);?是的，在request中得到getSession,然后再session.setAttribute("list", list);2) 2>一般情况下</logic:iterate>提交到actionForm到Action的？我更不明白了，请问下，如果你想在一个独立的页面里显示新闻列表，该怎么做？不能直接请求news.jsp吗？ 难道还要为这个页面写一个action？如果你的<logic:iterate>只是用来作结果输出的话，那么forward 到这个页面来就应该可以了。请参考： The iterate tag is probably the most complicated one in the logic tag library, but also one of the most useful. At its heart, it's pretty simple. You specify a collection with the name or name and property attribute, and specify a bean to hold the individual members of the collection in id. The tag then loops over each member of the collection (which can either be an array, a Collection, Enumeration, Iterator, or Map), setting the id to the element and evaluating its contents.主要是：You specify a collection ,property attribute,and specify a bean 以上三个是必须的，如果你的</logic:iterate>需要提交处理，但如果不处理就没有必要了。愚见，呵呵，仅供参考！！！

哦，原来这样，谢谢studyday(好好学习天天向上) 如果我不是做结果输出，而是事先在前台jsp页面显示数据用什么标签？
也就是用不到action的页面，该怎么办？
<bean:write name="fruit" />
</logic:iterate>fruito 为一个集合.
<html:form action="/aa/bb" method="post">
aa/bb和你转发的action对应，在xml通过<action path="aa/bb" name="ListForm"../>
及ListForm对应的你的ActionForm(aaForm extends ActionForm)
<logic:iterate id="userList" name="aaForm" type="aa.bb.cc.aaForm">
<tr>
<td><bean:write name="userList" property="username"/></td>
<td><bean:write name="userList" property="password"/></td>
<td><bean:write name="userList" property="email"/></td>
</tr>
</logic:iterate>name,type property都注意大小写了，看你的get set 怎么写了
如果Action ActionForm <html:form 这些没对应上，大小写没对，挂的我也没办法了：>
<logic:iterate id="userList" name="aaForm" type="aa.bb.cc.aaForm">
aaForm与aaForm extends ActionForm名字对应？还是与Action对应？我都搞胡了，不是在Action的execute方法里执行session.setAttribute("list", list);吗？谢谢两位
<logic:iterate id="userList" name="list" type="oa.hibernate.po.User" scope="request">
<tr>
<td><bean:write name="userList" property="username"/></td>
<td><bean:write name="userList" property="password"/></td>
<td><bean:write name="userList" property="email"/></td>
</tr>
</logic:iterate>userList是你在action里面定义的ActionForm
list是你从Action里面所存从库里面查出来的记录.一个ArrayList
如上面.
userList.setUsername(rs.getString("name"));
list.add(userList);
excute方法里面:
reqeust.setAttribute("list", list);
在jsp页面上如你所列出来的就可以调用了.
<form-beans>
<form-bean name="nameForm" type="com.my.StForm"/>
</form-beans> <action-mappings>
<action path="/aa/bb"
type="com.my.StAction"
name="nameForm"
scope="request"
parameter="operate"
unknown="false"
validate="false">
<forward name="success" path="aa"/>
</action>
</action-mappings>
</struts-config><html:form action="/aa/bb" method="post"><logic:iterate id="userList" name="StForm" type="com.my.StForm">
<tr>
<td><bean:write name="userList" property="username"/></td>
<td><bean:write name="userList" property="password"/></td>
<td><bean:write name="userList" property="email"/></td>
</tr>
</logic:iterate>
</html:form>
1、为了不在JSP中带许多《% %》，所以用户的请求还是发给Action处理；
2、在Action中用getSimpleProperty函数读取数据，例如：
String username = (String) PropertyUtils.getSimpleProperty(form, USERNAME);
String password = (String) PropertyUtils.getSimpleProperty(form, PASSWORD);
把数据收集到list中，再用reqeust.setAttribute("list",list);保存数据。
