我有一个在本地工作正常的webapp。当我尝试在新的debian安装上部署它（刚从oracle安装tomcat8和JDK 8）时，我的ContextListener上有一个ClassNotFoudn异常。日志中有痕迹显示侦听器已经启动，但（我认为）因为异常没有启动上下文而且每个URL都获得404.

：
@Override
public void contextInitialized(ServletContextEvent sce) {
System.out.println("Starting configuration");
if(testMode) {
System.out.println(" !! Running in test mode !!");
}
有什么想法吗？
答案 0 :(得分：0)
行：
开始配置
!!在测试模式下运行!!
..表明你的听众正在被执行;好。然后，行：
INFOS：部署Web应用程序存档/var/lib/tomcat8/webapps/chouette.war已于25 675 ms完成
..表示已部署chouette.war。
ClassNotFound发生在以下行之后：
INFOS：Déploiementdurépertoire/ var / lib / tomcat8 / webapps / ROOT de l'application web
...在我看来，正在部署第二个应用程序，其中您的课程没有被很好地包括在内。你最好检查ROOT目录。
