</xwork>当然你必须保证在你的web应用里有这几个xml文件:webwork-default.xml validators.xml components.xml 
这些文件在webwork包里面就有,如果没有就拷过来,不然你启动就报错!

这样呢

Answer 3

谢谢,楼上的回答.
不过我现在想用com.opensymphony.xwork.spring.SpringObjectFactoryListener这个方式来实现.不知道我的代码里哪里有错误呢?

Answer 4

是jar版本的问题，具体是哪个jar有问题我忘记了。
好像是xwork.jar的问题，你找个可以运行成功的例子，然后把里面的jar复制过来吧。
我被这个问题郁闷好几天：（

Answer 5

我试了,还是那样.是不是applicationContext里还要设置一些什么东西啊??

Answer 6

还有
2006-01-12 12:57:05,562 [http-8080-Processor5] DEBUG com.opensymphony.webwork.dispatcher.ServletDispatcher - Parameter access work-around disabled
这个到底是什么意思啊!

Answer 7

搞定了, pigo(白头霜)的方法是对的.我换成最新的.jar文件就可以用了.
