logic遍历的有关问题

logic遍历的问题

Java code

DBSource ds = new DBSource();if (url.equals("/command/currency.jsp")) {    List<Currencyiso> CurrList = ds.DBSourceforCurrencyiso();    request.setAttribute("CurrList", CurrList);    System.out.println("执行/command/currency.jsp");}

在访问页面时就触发上面的语句向request中添加一个被泛型的list数组
Currencyiso是由spring生成的bean

Java code

<logic:iterate id="CurrList" name="CurrList" scope="request"><option value='<bean:write name="CurrList" property="alphacode"/>' ><bean:write name="CurrList" property="alphacode"/></option></logic:iterate>

在页面中我用logic遍历
alphacode在Currencyiso有set/get方法
xml中名称也是对应的

但是我访问页面就出现如下错误：
执行/command/currency.jsp

望高手指点！！
不胜感激

[解决办法]
你的这个问题和我遇到的差不多，根据我的经验你应该把这个list定义到bean里面去，然后这样写
<logic:iterate id="CurrList" property="CurrList" name="bean的名字" scope="request">
具体的你看看我的blog
http://blog.csdn.net/panhf2003/archive/2008/09/23/2970193.aspx
看看对你有没有帮助
写的很粗糙，有不明白的你再问我
[解决办法]
你的服务器用的什么？
可以找到编译后的jsp文件，看看里面去访问的Currencyiso的什么方法。

我怀疑你虽然有get/set方法，可能是不是范型的原因，去访问的get并不是你写的。

jsp的编译后的文件目录:
tomcat的话,如果在servel.xml没有设置目录应该在
webapps\helloapp\work\


weblogic的话在user_projects\domains\xxx\xxx\\.wlnotdelete\extract
[解决办法]
你把你的id换成别的名称试一下,别让id和name属性值都是CurrList.
注意代码编写的规范.
[解决办法]
No getter method for property: "alphacode" of bean: "CurrList" 
没找到get方法
仔细检查Currencyiso类，中的属性alphacode的get/set方法吧
[解决办法]

探讨

bean中肯定没有问题
bean是spring生成的
不知道是不是xml的问题

还有其它的问题……

HTML code

<logic:present name="CurrList"> <logic:iterate id="CurrList" name="CurrList" scope="request"> <option value=' <bean:write name="CurrList" property="alphacode"/>' > <bean:write name="CurrList" property="alphacode"/> </option> </logic:iterate> </logic:present>
[解决办法]
查查字段alphacode，看BEAN里面是否缺少get/set方法
[解决办法]
这里 <option value=' <bean:write name="Curriso" property="alphacode"/>' > <bean:write name="Curriso" property="alphacode"/> </option>
改写成
<html:options collection="currList" property="alphacode"/>
试下
[解决办法]
javax.servlet.jsp.JspException: No getter method for property: "alphacode" of bean: "CurrList"  
你应该把CurrList定义到你的form里面
public MyForm exends ActionForm{

}
[解决办法]

小女子 不懂,关注中
帮楼主顶吧
[解决办法]
  不知道你的问题解决了没有，我好像以前也遇到过这样的情况，估计是你formbean中定义get,set方法是其自动生成的，你看是不是定义的属性和其对应的方法名大小写不规范（自动生成的有可能），把大写改为小写，然后再测试一下。
[解决办法]
 
  
  <logic:iterate id= "currencyiso " property= "Currencyiso " name= "CurrList " scope= "request ">   
  
      <option value= ' <bean:write name= "currencyiso " property= "alphacode "/>  ' >  
            <bean:write name= "currencyiso " property= "alphacode "/>  
      </option>  
  
  </logic:iterate>  
  

[解决办法]
<logic:iterate id="CurrList" name="CurrList" scope="request" type="你的CurrList的类名">
<option value='<bean:write name="CurrList" property="alphacode"/>' ><bean:write name="CurrList" property="alphacode"/></option>
</logic:iterate>
