    楼主你的ACTION 呢？？？public void reset(ActionMapping actionMapping,
                        HttpServletRequest httpServletRequest)
      {  }
    }
    中初始化一下啊
      

  3.   

    据我看是类型不匹配出的错.在这句中
    <html:select  property="docTypeIds" style="width:120px" size="10">
       <html:options  property="docTypeIds" labelProperty="docTypeNames"></html:options>
      </html:select>
    select的结果肯定是一个固定值,所以应该返回一个String,而你在property里用的一个vector去接,当然会出错了,你应该在form里定义一个String docTypeid及他们get,set方法,然后
    <html:select  property="docTypeId" style="width:120px" size="10">
       <html:options  property="docTypeIds" labelProperty="docTypeNames"></html:options>
      </html:select>
    这样就对了,其他的html:select也是同样的错误.
    写了一大堆,不知道你明白我的意思没有.
