Question

我有一个servlet应用程序我试图部署到我的本地tomcat实例。起初我尝试使用tomcat管理器应用进行部署，但被告知有一种更简单的方法 - 只需将.war放在webapps - 文件夹中。（/etc/tomcat8/webapps/在我的机器上）

重新启动tomcat服务但是我收到错误：

    Job for tomcat8.service failed because the control process exited with error code. See "systemctl status tomcat8.service" and "journalctl -xe" for details.

journalctl -xe输出如下：

我怀疑这是我本地环境（新安装）的配置错误，但无法确定它究竟是什么！我尝试重新安装，但过了一段时间我再次陷入同样的死胡同......任何想法？

编辑：这是systemctl status tomcat8.service的输出：

我发现终端输出在这里有点误导。显然有一个名为Catalina.log的日志文件（在ubuntu上默认为/var/lib/tomcat8/conf/catalina.log）。这就是我遇到麻烦的真正原因所在。显然我的server.xml配置存在问题（文件丢失）。

这里有更广泛的教训 - 在遇到tomcat问题时检查你的catalina.log！

在tomcat8中启动.war servlet
