            <b>问题：</b> list里面放的实体对象，页面用c:foreach应该怎么取？<br>

            <strong>描述:</strong><p></p><pre>User&nbsp;user=null;<br>

	String&nbsp;hql="select&nbsp;uid,nickName&nbsp;from&nbsp;User";<br>

	List&lt;Object[]&gt;&nbsp;receiverList=emailService.getListByHql(hql);<br>

	List&lt;User&gt;&nbsp;tempList=new&nbsp;ArrayList&lt;User&gt;();<br>

	for(Object[]&nbsp;objs:receiverList)<br>

	{<br>

		user=new&nbsp;User();<br>

		user.setUid((Integer)objs[0]);<br>

		user.setNickName((String)objs[1]);<br>

		tempList.add(user);<br>

	}<br>

	System.out.println(tempList.size());<br>

	System.out.println(tempList.get(0).getUid());<br>

	System.out.println(tempList.get(0).getNickName());<br>

	Map&nbsp;request=(Map)ActionContext.getContext().get("session");<br>

	request.put("receiverList",&nbsp;tempList);<br>

	return&nbsp;SUCCESS;</pre><br>

<select name="receiver">

<c:forEach var="receiver" items="${receiverList }" varStatus="vs">

<option value="${receiver.uid }">${receiver.nickName }</option>

</c:forEach>

</select>

我在页面上这样写根本取不到，报

javax.el.PropertyNotFoundException: Property 'uid' not found on type java.lang.String

异常

这要检查你的 User 实体类，User 是否有uid属性，并且是否有get set方法！

    </p><strong>解决方案2:</strong><p>            区分大小写某

    </p><strong>解决方案3:</strong><p>            &lt;c:forEach&nbsp;var="receiver"&nbsp;items="${page.receiverList&nbsp;}"&nbsp;varStatus="vs"&gt;

    </p><strong>解决方案4:</strong><p>            页面用${sessionScope.receiverList&nbsp;}取值

    </p><strong>解决方案5:</strong><p>            ActionContext.getContext().getSession().put("receiverList",&nbsp;tempList)<br>

用这种放放到session中    

再不行的话，你换成structs的迭代标签
