Cannot find bean under name myList

[casesky]

jsp

<html:select size="1" property="dc_parent_id" >
<html:options name="myList"/>
</html:select>

form:

/**
* 分类
*/
private Integer dc_parent_id;

action:

SelDocDBS seldoc = new SelDocDBS();
List myList = seldoc.root();
httpServletRequest.setAttribute("myList",myList);

error:

Cannot find bean under name myList

找不到阿
加上score="request"试试看呢？

[csqok]

<html:options collection="myList" />

[casesky]

score?
加到哪里？

[casesky]

<html:options collection="myList" />
同样的错

[csqok]

<td><html:select name='user' property='right' disabled='true'>
<html:options collection="levelList" property="value" labelProperty="label" />
</html:select></td>

import java.util.List;

ArrayList arryList= new ArrayList();
arryList.add(new LabelValueBean("1111","1"));
arryList.add(new LabelValueBean("2222","2"));
List levelList=arryList;
request.setAttribute("levelList",levelList);

[casesky]

看不懂啊。LabelValueBean是什么？

[csqok]

import org.apache.struts.util.LabelValueBean;

[casesky]

action:

SelDocDBS seldoc = new SelDocDBS();
List myList = seldoc.root();
httpServletRequest.setAttribute("myList",myList);

需要从action中读出数据生成一个List，在select中显示出来。
这么做到地哪出错了？

有把myList类放到scope里面嘛,比如request/session/pageContext/application?通常这一步在action中完成,比如先request.setAttribute("myList",your bean instance),然后在返回ActionForward对象或者直接转向到jsp页面.
上面出现的问题应该是在scope域里面找不到你要显示的名为myList的bean.

action:

httpServletRequest.setAttribute("myList",myList);
httpServletResponse.sendRedirect("/docc_add.jsp");
是这样吗?还是那个错！

<td><html:select name='user' property='right' disabled='true'>
<html:options collection="levelList" property="value" labelProperty="label" />
</html:select></td>

ArrayList arryList= new ArrayList();
arryList.add(new LabelValueBean("1111","1"));
arryList.add(new LabelValueBean("2222","2"));
request.setAttribute("levelList",arryList);

collection="levelList" 的名字和setAttribute("levelList"中的levelList的值一样就可以的。

嗯，好像必须用labelValueBean吧，不用的我没试出来过

httpServletRequest.setAttribute("myList",myList);
httpServletResponse.sendRedirect("/docc_add.jsp");

不要用sendRedirect，用forward（），前者是重新发送一个request，那么你前面放在request里面的mylist已经不存在了，jsp里面肯定找不到了，其他同意 lcz022(阿五)。
