我们正在尝试在CentOS 7上安装shibboleth IdP，并按照SWITCH指令（https://www.switch.ch/aai/guides/idp/installation/）加入SWITCH Federation。
Tomcat开始正常运行，但idp战争未启动。 Tomcat日志如下：

由于我们不熟悉Java，因此我们首先从maven存储库中将opensaml-2.6.4.jar和opensaml-core-3.3.0.jar下载到/ opt / shibboleth-idp / edit-webapp / WEB-INF / lib，然后重建战争，但仍然没有运气。 任何解决我们问题的建议将不胜感激。 非常感谢你！
