Unable to load bean: type: struts-derfault.xml异常

很多朋友在使用Struts2时都会遇到这个异常，导致其主要原因还是因为加错了包,大家只要将xwork-2.1.1.jar和struts2-core-2.1.2.jar，换成xwork-2.0.4.jar和struts2-core-2.0.14.jar或者struts2-core-2.0.14.jar

 这个包就可以了，为什么会有这个原因，本人还没去研究，也还没有去查询。如果大家有见解请指导指导。

如果tomcat/lib和WEB-INF/lib下面同时有struts的jar包，也会报这个错误。

仔细看下struts2-core-2.1.2.jar及struts2-core-2.0.14.jar，为什么？我也碰到你这样的错误！我用的包是xwork-2.0.1.jar及struts2-core-2.0.6.jar,我的错误跟你一致。
