你的分析：
我是webwork2的初学者.我在按照从满江红网站上下载下来的文档学习.在我学习到validation验证的时候,我执行了例子.可验证后并没有返回输入页面.出现一个空白页面.按文档里说,如果同时指定三个拦截器就会自动返回到输入页面.不知道是不是我理解有误,还是什么别的问题.新各位高手,指点下小弟.
为什么我除去这一个<interceptor-ref name="workflow"/>这一个拦截器就可以在出问后返回输入页.加上就会出现空白页.不过去掉过.发现ACTION一样的被执行了.
我把JAR包换成了2.1版的,问题还是这样,而且requiredstring验证可以,用require就没有效果.还抛出殿堂.(2,1,7版没有异常出现),其它情况和2.1.7版一样.
反复检查多少不知道问题是什么,我想是不是程序找不到输入页.或者workflow的问题.在API里也查不到它的具体解释.有些心急.
不好意思.版主.在新手区等了一下午也没有人理我.只有再次发贴.希望不要删贴.至少给个理解.

我说的执行是execute()都执行了.

有一个提示. DefaultAction W com.opensymphony.xwork.DefaultActionInvocation  No result defined for action test.LoginAction and result input

我看了资料说workflow就是不执行execute(),然后返回输入页.而我的情况是定在一个空页面没反应.如果去掉workflow能返回.但应该是因为执行完action后由action控制的返回.一定是workflow找不到输入页.可我不知道为什么.也没有什么文章提示需要配置什么.

晕了.
加一个
<result name="input"  type="dispatcher">
     <param name="location">/index.jsp</param>
</result>
在xwork.xml里就好了.

怎么在开发指南里没有看到....难道是我眼花了,还是有什么别的办法.

而且required也不起作用.
用了requiredstring才行.
