关于struts的validate问题

学习struts有半年了,一直extends ActionForm写validate,rest方面来检验.郁闷了半年从没有成功使用validation框架。虽然是
基础的东东，但是实验了多少天都没有成功，还是得求 教大家，下面是非常简单的测试文件，还是请各位指点一句半句，感激不尽。：）

同时我还试过不用在struts_config中配置DynaValidatorForm,而是手写TestForm extends ValidationForm.但是这样提交之后，那个
<form name="testForm">
      <field property="name" depends="required">
        <arg0 key="name"/>
      </field>   
    </form>好像不起做用，倒也没有任何错误提示。。郁闷...

没看明白，不是直接extends ActionForm以后重写validate不就可以了吗？

但是我不想写rest,validate方法，而想用validate.xml中定义的去验证，但是从没有实验成功

哈，这个问题是你的struts的版本和common-validator的版本不一致，
我也碰到过。
我那次从struts1.2.4升级到struts1.2.8的时候就出现这个问题的

我现在还是用的struts1.2.4和common-validator1.1.3,这个没有问题

谢谢您的指点，我晚上回去试试，可能真是您说的这样》：）

最好拷贝发行包中的struts－example中所带的validator-rules.xml和validation.xml
然后在此基础上改，免得出错

感谢各位回复，真是版本的问题，我原先用的是struts1.2.4可能和那个版本的validator不能一起使用，现在用1.1.3的validator就好了：），问题终于解决了，一身轻松。

java.lang.NoSuchMethodException
这个一看就是包有问题了
