数据库：
userinfo（uid（int),****,code（int),did（int))对应userform
code（codeid（int),codename（varchar))对应一个list
表关系
userinfo.code=code.codeid
struts高人指点下拉列表问题
代码：
session.setattribute（ "userform ", userform);
session.setattribute（ "list ", list);
页面：
这个用到了tiles框架
将要修改的值从一个action传到这个页面，修改后提交
<%@ page language= "java " pageencoding= "gbk "%>
<%@ taglib uri= "http://struts.apache.org/tags-bean " prefix= "bean " %>
<%@ taglib uri= "http://struts.apache.org/tags-html " prefix= "html " %>
<%@ taglib uri= "http://struts.apache.org/tags-logic " prefix= "logic " %>
<%@ taglib uri= "http://struts.apache.org/tags-tiles " prefix= "tiles " %>
<%@ page import=com.zengbo.struts.form.* %>
<%
userform userform = （userform)session.getattribute（ "userform ");
string code = userform.getcode（)+ " ";
%>
<p align= "center "> 更新数据 </p>
<p align= "left "> <html:link href= "./user.do?operator=getfirstpage "> 回显示页面 </html:link> </p>
<html:form action= "/user.do?operator=ＥＸＥＣuteupdate " method= "post ">
<table align= "center " border= "1 ">
<tr>
<td> 用户名： </td> <td> <html:text property= "username " name= "userform "/> </td> <html:hidden property= "userform "
value= "uid "/>
</tr>
<tr>
<td> 密 码： </td> <td> <html:text property= "password " name= "userform "/> </td>
</tr>
<tr>
<td> email： </td> <td> <html:text property= "email " name= "userform "/> </td>
</tr>
<tr>
<td> 状 态： </td> <td> <html:radio property= "state " value= "0 " name= "userform "/> 启用
<html:radio property= "state " value= "1 " name= "userform "/> 禁用 </td>
</tr>
<tr>
<td> 部 门： </td>
<td>
<!--获取表单对应的值进行修改-->
<html:select property= "code " value= " <%=code%> ">
<html:options collection= "list " property= "codeid " labelproperty= "codename "/>
</html:select>
</td>
</tr>
<tr>
<td> <html:submit value= "提 交 "/> </td> <td> <html:reset value= "重 置 "/> </td>
</tr>
</table>
</html:form>
我现在删除
<html:select property= "code " value= " <%=code%> ">
<html:options collection= "list " property= "codeid " labelproperty= "codename "/>
</html:select>
页面可以正常显示，如果加上下拉列表就报错！！
org.apache.jasper.jasperexception: /useredit3.jsp（7,17) quote symbol expected
org.apache.jasper.servlet.jspservletwrapper.handlejspexception（jspservletwrapper.java:512)
org.apache.jasper.servlet.jspservletwrapper.service（jspservletwrapper.java:377)
org.apache.jasper.servlet.jspservlet.servicejspfile（jspservlet.java:314).....
........
如果让页面没有java代码要如何改，下面这样可以吗？
<html:select property= "code " value= " <bean:write name= "userform " property= "code "/> ">
<html:options collection= "list " property= "codeid " labelproperty= "codename "/>
</html:select>
