部署的应用程序成功但无法启动

Question

我目前在debian jessie中使用java 1.8 tomcat8。我可以通过tomcat管理器部署我的应用程序，但无法重新启动。我在日志上遇到了这个错误。

20-Feb-2016 16:16:15.063 SEVERE [http-nio-8080-exec-20] org.apache.catalina.core.StandardContext.startInternal One or more listeners failed to start. Full details will be found in the appropriate container log file

To prevent a memory leak, the JDBC Driver has been forcibly unregistered.

我也在控制台上收到此错误：

有人可以帮我理解这些错误吗？我不是java，我只是部署它的人。
