Exception sending context initialized event to listener instance of class

1、错误描述

严重：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:‘com.you.yhd.webapp.root‘ = [D:\myeclipse\Tomcat6.0\webapps\ROOT\] instead of [ D:\myeclipse\Tomcat6.0\webapps\ROOT.myeclipse.bak\] -Choose unique values for the ‘webAppRootKey‘ context-param in your web.xml files!

2、错误原因

     Tomcat中部署了多个项目，并且ROOT.myeclipse.bak是一个项目，后来又添加一个项目，导致两个项目中的web.xml参数不一样

3、解决办法

     删除不需要部署的项目，保证Tomcat每次只执行一个项目
