Question

我们将websphere 17用于基于eclipse-link作为持久层的Web应用程序。应用程序运行正常，但过一会儿（在用户活动期间），我们收到了此类错误，迫使我们重新启动服务器。

org.eclipse.persistence.exceptions.DatabaseException
Internal Exception: java.sql.SQLException: Access denied ("java.util.PropertyPermission" "oracle.jdbc.sqlTranslationProfile" "read")
Error Code: 0

此错误是什么意思？

据我了解，发生此错误是因为没有对该属性的读取权限。但这可能是由于安全管理器所致。问题是我希望websphere设置任何安全管理器，并且可以肯定的是我们不会创建任何自定义安全管理器。安全管理器不应该存在于我们的应用程序中。那么，谁来设置呢？还是我错过了什么？

以下是完整的堆栈跟踪：

感谢您的帮助，

bootstrap.properties中的websphere.java.security属性控制是否在Liberty中启用Java 2安全性。

在启用Java 2安全性的情况下运行时，以下示例服务器配置代码段（用于server.xml文件）说明如何授予oracle JDBC驱动程序读取以“ oracle.jdbc”开头的系统属性的权限，< / p>

<javaPermission codebase="C:/drivers/oracle/ojdbc7.jar" className="java.util.PropertyPermission" actions="read" name="oracle.jdbc.*"/>

访问被拒绝读取java.util.Permissions
