嚴重: Exception sending context initialized event to listener instance of class org.springframework.web.util.Log4jConfigListener

java.lang.IllegalStateException: Web app root system property already set to different value: 'SpringMVC.root' = [D:\apache-tomcat-6.0\webapps\cdm\] instead of [D:\apache-tomcat-6.0\webapps\cdm.myeclipse.bak\] - Choose unique values for the 'webAppRootKey' context-param in your web.xml files!

緣由是tomcat的webapps下有兩個一樣的項目，刪除從新發布便可
