我的jsp页面代码如下：
<%@ page language= "java " pageEncoding= "UTF-8 "%>
<%@ taglib uri= "/WEB-INF/struts-bean.tld " prefix= "bean " %>
<%@ taglib uri= "/WEB-INF/struts-html.tld " prefix= "html " %>
<%@ taglib uri= "/WEB-INF/struts-logic.tld " prefix= "logic " %>
<%@ taglib uri= "/WEB-INF/struts-tiles.tld " prefix= "tiles " %>
<%@ page import= "java.util.*,org.apache.struts.util.LabelValueBean " %>

ArrayList list=new ArrayList();
list.add(new LabelValueBean( "show value1 ", "value1 "));
list.add(new LabelValueBean( "show value2 ", "value2 "));
list.add(new LabelValueBean( "show value3 ", "value3 "));
list.add(new LabelValueBean( "show value4 ", "value4 "));
pageContext.setAttribute( "valuelist ",list);
%>
<html:select property= "abc ">
<html:options collection= "valuelist " property= "value " labelProperty= "label " />
</html:select>
</body>
</html:html>
执行的时候确报告这种异常：
org.apache.jasper.JasperException: Exception in JSP: /manager/AddCD.jsp:38
35: list.add(new LabelValueBean( "show value4 ", "value4 "));
36: pageContext.setAttribute( "valuelist ",list);

38: <html:select property= "abc ">
39: <html:options collection= "valuelist " property= "value " labelProperty= "label " />
40: </html:select>
