大家好,我遇到了Tomcat 8无法启动服务的问题。使用设置的用户名和密码成功安装了Tomcat 8.0.30。它已成功获取BIMserver的最新.war文件版本,并根据配置进行了自动部署。然后,BIMserver服务无法启动。转到Tomcat管理器后,我们无法手动启动该服务,因为它会引发错误FAIL - Application at context path /BIMserver could not be started

我曾尝试使用Tomcat 8和7的早期版本,但得到相同的错误。关于启动侦听器的问题有什么想法?

最佳答案

org.bimserver.web.WarServerInitializer java.lang.UnsupportedClassVersionError:org / bimserver / web / WarServerInitializer:不支持的major.minor版本52.0(无法加载类org.bimserver.web.WarServerInitializer)


您需要使用Java 8运行tomcat或重新编译有问题的类以产生与Java 7兼容的字节码。
