启动tomcat 的 struts2 错误
严重: Exception starting filter struts2
Unable to load configuration. - bean - jar:file:/F:/Struts2/Struts2/WebRoot/WEB-INF/lib/struts2-core-2.1.2.jar!/struts-default.xml:46:178
at com.opensymphony.xwork2.config.ConfigurationManager.getConfiguration(ConfigurationManager.java:58)

--解决：
commons-io-1.3.2, commons-fileupload.1.2.1这两个jar包放到lib下
