我在tomcat（jdk 7）上部署我的war文件，并且看到了以下错误。我不确定是什么导致了这个问题。

您可以通过将/WEB-INF/classes/logging.properties添加到您的war存档来重新配置java.utils.logging：
org.apache.catalina.core.ContainerBase.[Catalina].level = INFO
org.apache.catalina.core.ContainerBase.[Catalina].handlers = java.util.logging.ConsoleHandler
然后应该显示实际的错误消息。此外，如果已配置其他日志记录框架（例如，log4j），请检查应用程序日志。

您安装的JDK版本和正在尝试构建项目的JDK可能不匹配。
1）如果您正在使用 Eclipse 。转到Windows->Preferences->Compiler->check编译器合规性级别（它应该与您安装的JDK匹配）
2）
build.xml Select Run As->Ant Build...请注意省略号！构建项目
