楼主,我来收你的120分了.

你犯了一个低级错误.

cn.hxex.order.action.RegisterAction这个action中

public RegisterAction() { // 这里缺少了 public,导致无法访问,所以struts的配置提示有错误
super();
}

加上就好了.至于其他的功能 我没有仔细看.

另外说下 这个不是你写的项目吧,你是不是在已有的基础上,尝试学写代码的?

有问题再说了,

结贴给分,我要冲星星

这贴你在其他模块是不是也有发。

IllegalAccessException当应用程序试图创建一个实例（而不是数组）、设置或获取一个字段，或者调用一个方法，但当前正在执行的方法无法访问指定类、字段、方法或构造方法的定义时，抛出的异常。

你仔细看一下RegisterAction，RegisterAction有问题。主要看方法调用是否有问题。

我觉得很奇怪，你不是用了spring了，既然已经交给spring控制了，为什么你的Struts.config.xml没有显示这一点呢！

直接继承Action是没问题，但这样就没法获取spring中的 getBean("registerSerice")事务了。我认为是spring业务层接口IRegisterSerice.java 、实现RegisterSericeSpring.java 、业务层接口IRegisterSerice.java 、
持久层实现：RegisterhibernateDAO.java 。这几个文件中的方法出了问题 。感谢大家帮忙分析，不过现在还知哪错了。

估计还是继承BaseAction那里有问题，如果直接继承Action的话应该不会报错了...

贴了这么多代码，看都头晕，大概的看了下，你的Struts.config.xml 配置 ,你有没有贴全啊，如果就是这样的话肯定不对的吧

<form-beans>
<form-bean name="RegisterForm"
type="cn.hxex.order.forms.RegisterForm" />
</form-beans>
<action path="/Register"
type="cn.hxex.order.action.RegisterAction" name="RegisterForm"
input="/pages/register.jsp" scope="request">
<forward name="sucess" path="/pages/afterRegister.jsp" />
</action>


你看看你的type属性既然你用了spring，为何还是“cn.hxex.order.action.RegisterActi”应该还有下面的代码吧

<controller processorClass="org.springframework.web.struts.DelegatingRequestProcessor" />
<message-resources parameter="com.***.ApplicationResources" />
<plug-in
className="org.springframework.web.struts.ContextLoaderPlugIn">
<set-property property="contextConfigLocation"
value="/WEB-INF/applicationContext.xml" />
</plug-in>

}


public IRegisterDAO getRegisterDAO() {
