我把struts下LIB全拷进去了。 好像可以了，又出其他问题了。严重: Exception sending context initialized event to listener instance of class org.springframework.web.context.ContextLoaderListener
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'dataSource' defined in file [E:\java\Tomcat 6.0\webapPS\cifco\WEB-INF\classes\applicationContext-resources.xml]: Initialization of bean fAIled; nested exception is java.lang.NoSuchMethodError: org.springframework.util.ClassUtils.getMostSpecificMethod(Ljava/lang/reflect/Method;Ljava/lang/Class;)Ljava/lang/reflect/Method;

类未找到!
1 类虽然都放进去了,但不一定都被加载了
2 你的Lib下的Jar包不全,某些Jar包并不是在编译期使用的,而是要在运行期使用,也就是说是你使用的某个Jar包的依赖库,这些库也要一起放进去

这些都是提示找不到类，肯能是由于有些必须类你没有放到lib里面去。

struts2核心类不止一个.其他几个都要放进去

struts2需要5个jar包，加到lib目录下就好了
