在页面中显示不正确啊。

[mbh0210]

程序如下：
在Action中：
combinsql combin=new combinsql();
Vector table_field=new Vector();
verygood very=new verygood();
Vector ver=new Vector();
ver.add(combin.filed_name());
very.setMbh(ver);
table_field.add(very);
httpServletRequest.setAttribute("table_field",table_field);
ver里面保存的是数据库中一个表的字段名。比如是申请单编号, 计划编号, 申请日期，我想在网页中把他显示出来，但显示的是[[申请单编号, 计划编号, 申请日期,]]，并不是申请单编号 计划编号 申请日期 这中格式啊，急啊，请大侠解决一下啊。其他的都没有错，就是Vector这里有问题。

贴出完整代码

vector是遗弃的类,为何不用arraylist?

[dropship]

一般,vector是用addElement来添加元素的，并且元素一定是对象
你这个是啥清楚吗？
ver.add(combin.filed_name());
给你java doc的英文说明
