我用的是spring2.5，hiernate3.2,struts1.2。做一个简单的用户注册时出问题了！

可你Action里面的方法名是register啊，
所以这里应该改成parameter="register"
楼上，不好意思，你说错了，parameter="status"不是你说的意思<action
attribute="userForm"
input="/jsp/errors.jsp"
name="userForm"
parameter="status" path="/jsp/user"
scope="request"
type="com.jun.bbs.struts.action.UserAction">
<forward name="registersuccess" path="/jsp/index.jsp"/>
<forward name="registerfailure" path="/jsp/register.jsp"/>
</action>parameter的意思是说，
如果你想调用某个action的某个方法，要通过parameter所指定的参数名来指明方法名。听起来有些绕，举个例子：比如你在Struts－config.xml中定义了一个Action:
myAction
然后，你需要访问myAction这个类的register方法，按照你上边的约定，应该在URL中输入：
/myAction.do?status=register所以，这就是为什么struts自己带的例子，都把parameter参数设置成：method
parameter="method"因为这样写出的URL可读性高：
/myAction.do?method=register
或者 你在web.XML里加个控制器<controller processorClass="org.springframework.web.struts.DelegatingRequestProcessor"></controller>
这里我确定没有问题！<input type="hidden" name="status" value="register">
改成你说的这个
异常如下：

很久没弄 还是带你跑了下看看 的确是这样 改了就可以跑了:)
恩！楼上的改了是不报错了!但是，还是不能进入到Action中去
org.apache.struts.action.DynaActionForm
如果，我改成动态表单验证会出问题么。配置照上面的
把错误发出来.如果你改成动态表单 原理是不变的 只是修改下Action里的name=你的动态表单名就可以了 应该是没问题的

</web-app>所有的信息都到这里了！9楼的是运行tomcat的信息！验证码是null在Action中可以打印出来，但是，验证码错误就没有到error.jsp上去！只是，跳转了地址栏信息为：user.do谢谢你们三位的回复。尤其是，依者西也
不过既然可以进入到Action,问题就很好办 你只需要设个断点 跟踪调试下 应该很快能找到你问题所在:)
我用了单步调试。就是不进入Action啊！运行完Action就跳到Deamo Thead！然后就完了！
validate方法会根据你的返回值进跳转页面。如果validate返回值不为null，那struts就认为有错误，转到input页面。如果validate方法的返回值为null，struts认为验证通过，那就会跳转到Action。而你的validate方法无论验证通过没有都会返回一个ActionErrors对象，并不会在验证通过时返回一个空。建议改成如下：public ActionErrors validate(ActionMapping mapping,
HttpServletRequest request) {
ActionErrors errors = new ActionErrors();
if(type == 1) {
if(this.userid == null || "".equals(this.userid)) {
errors.add("userid",new ActionMessage("user.userid.null"));
}
if(this.userpwd == null || "".equals(this.userpwd)) {
errors.add("userques",new ActionMessage("user.userpwd.null"));
} else {
if(!(this.userpwd.equals(this.confirmpwd))) {
errors.add("configpwd",new ActionMessage("user.confirmpwd.error"));
}
}
if(this.userques == null || "".equals(this.userques)) {
errors.add("userques", new ActionMessage("user.userques.null"));
}
if(this.userans == null || "".equals(this.userans)) {
errors.add("userans", new ActionMessage("user.userans.null"));
}
if(this.checkcode == null || "".equals(this.checkcode)) {
errors.add("checkcode",new ActionMessage("checkcode.null"));
}
} if(errors.size()>0){
return errors;
}else{
return null;
}
}
那个类是跟spring整合的时候，在spring的配置文件里要定义的。
现在给出正确答案（呵呵，如果不对，再找我）：1、你原来的配置基本上很好，都已经到了form验证了，说明一切没有问题，保持，
2、如果现在已经调乱了，想办法调回去，相信你能够办到
3、问题在你的Action的Register方法，方法签名不对
Struts要求方法签名必须依次接收四个参数，才能调用到：
ActionMapping mapping, ActionForm form, HttpServletRequest request, HttpServletResponse response
看样子你是自己用到哪个参数，就写了哪个，这样不对嘀，struts用类反射查不到。
public ActionErrors validate(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response) {
ActionErrors errors = new ActionErrors();
if(type == 1) {
if(this.userid == null || "".equals(this.userid)) {
errors.add("userid",new ActionMessage("user.userid.null"));
}
if(this.userpwd == null || "".equals(this.userpwd)) {
errors.add("userques",new ActionMessage("user.userpwd.null"));
} else {
if(!(this.userpwd.equals(this.confirmpwd))) {
errors.add("configpwd",new ActionMessage("user.confirmpwd.error"));
}
}
if(this.userques == null || "".equals(this.userques)) {
errors.add("userques", new ActionMessage("user.userques.null"));
}
if(this.userans == null || "".equals(this.userans)) {
errors.add("userans", new ActionMessage("user.userans.null"));
}
if(this.checkcode == null || "".equals(this.checkcode)) {
errors.add("checkcode",new ActionMessage("checkcode.null"));
}
}
return errors;
}
首先我不是瞎指挥,我只是就问题分析,它这本身就是跟Struts和Spring整合,怎么不能用DelegatingActionProxy,当然还有一种方式就是用DelegatingRequestProcessor,那需要多加个控制器,我习惯用的是前者.第二,我不知道你那"正确答案"怎么正确,他那validate方法是重写的父类ActionForm的validate方法,方法签名她写的本来就是对的
你那方法我不知道怎么会有,里面传的参数貌似action里方法的参数.它的代码我拷下来运行了 的确是能跑起来的
你楼上那位说errors不为null也显然是不对的!
可事实不是这样的,我搞不清楚ActionErrors是靠什么来标识的,也许就是size,也许里面加了个标识,也许是看里面的message是不是为空,
但绝对不是根据为不为空返回的.
确实像“默然”所说，应该是靠NULL来判断是否有错的。
但确实指挥错了地方。楼主的jsp/user这个Action，是人家自己写的一个Action，所以type必须等于自己的类。而DelegatingActionProxy这个类，是spring提供的，确实要配置，但确实不是在这里。
Action中接收seesion中传来的验证码的值，和输入的对比。是否相等！就是觉得可能是那个配置出了点问题。而控制台不报异常和错误！
我就郁闷 了！所有，问问大伙有没有遇到过！
你是用什么action?
