Unable to load configuration. - bean - jar:file:/C:/Program%20Files/Apache%20Software%20Foundation/Tomcat%206.0/webapps/Struts2Demo01/WEB-INF/lib/struts2-core-2.1.8.jar!/struts-default.xml:47:178

解决办法：

除了
commons-logging-1.0.4.jar
freemarker-2.3.12.jar
ognl-2.6.11.jar
struts2-core-2.1.2.jar
xwork-2.1.1.jar

这五个核心LIB要复制外，
commons-io-1.3.2.jar
commons-fileupload-1.2.1.jar

这两个Jar文件也必须放到指定目录
