action 中
List wardList = wardDAOIface.findAll();
request.setAttribute("wardList", wardList);
jsp中
<body>
<html:select style="width:200"
property="${ward}">
<html:optionsCollection property="${wardList}"
value="ward" label="ward" />
</html:select>
</body>
报错：javax.servlet.jsp.JspException: Cannot find bean under name
org.apache.struts.taglib.html.BEAN
原因：<html:select
/> 必需用在
<html:form/>标签中
例如：
<html:form action="kkkkkk.do">
<html:select
style="width:200"
property="${ward}"
>
<html:optionsCollection
property="${wardList}"
value="ward"
label="ward" /
>
</html:select >
</html:form>
List wardList = wardDAOIface.findAll();
request.setAttribute("wardList", wardList);
jsp中

<html:optionsCollection property="${wardList}"
value="ward" label="ward" />
