如何用程序动态修改myeclipse中的<html:select>标签？

<list list=（list)request.getattribute（"xxx");>
<html:select property="xxx">
   <%for（int i=0;i<list.size（);i++){
        xxx xxx=list.get（i);
   %>
       <html:option value="<%=xxx.getxxx（)%>"><%=xxx.getxxx（)%></html:option>
   <%}%>
</html:select>

<html:select property="xxx">
   <logic:iterate id="发送过来时属性名" name="xxx" type="xx.xxx">
      <option value='<bean:write name="xxx" property="属性名"/>'>
         <bean:write name="xxx" property="属性名"/>
      </option>
   </logic:iterate>
</html:select>
