我正在部署一个Web服务（使用METRO 2.0库并将其包含在war文件中），并在tomcat上使用security manager启用了
-Djava.security.manager
-Djava.security.policy=C:apache-tomcat-8.5.6confcatalina.policy
我得到以下异常
SEVERE [localhost-startStop-1]

另一方面，没有security manager-一切都很好。
搜索后，我开始了解问题是javax/xml/bind/annotation/XmlNsForm均在tomcat库中和METRO 2.0中找到。
所以我有2个问题：
1. catalina.policy中是否有某种属性可以避免此问题。
2.还有其他方法可以解决这一冲突，而无需从war删除Metro 2.0。
预先感谢。
因此，解决方案不使用Metro 2.0的整个捆绑包 - 只有捆绑包的某些库（添加为 jars不像netbeans中的整个捆绑包）
