这个好像是配置问题，但是我是按照教学视频做的，怎么他的没出问题，我的出问题呢？
我的 struts2.3.1.2的版本，请大神帮忙解答，谢谢。

java ee --------------------编程问答-------------------- 在struts.xml里，action配的class是LoginAction，但实际的是loginAction --------------------编程问答-------------------- Caused by: Action class [org.fkjava.struts2qs.action.LoginProAction] not found - action - fil

没找到Action 类名写错了吧！ --------------------编程问答-------------------- 我把类名改过来了，但是问题还是那个问题，没变。 --------------------编程问答-------------------- clean了再试一下。 --------------------编程问答-------------------- 用了spring 没有？或多或少跟jar包有关
以下百度来的：
如果你的struts.xml和applicationContext.xml都配置正确，还报以上的错误，那么可以判断你的项目缺少jar包：

struts2-spring-plugin-2.0.11.1.jar、commons-fileupload-1.2.1.jar和commons-io-1.3.2.jar

导入这些jar包就行了，这些jar可以在struts-2.2.1的lib下找到。

在搭工程的时候，commons-fileupload-1.2.1.jar和commons-io-1.3.2.jar要是忘记了，报错很容易就看出来少哪些jar包，
但是struts2-spring-plugin-2.0.11.1.jar不太容易发现。
