问题描述：

目前处于使用Apache Jackrabbit和Oracle数据库进行评估的早期阶段。当测试的repository.xml配置的初始设置，收到此错误：Root Node Bundle上的唯一约束违规，Oracle Jackrabbit with Oracle

调试，我可以看到，它首先检查，如果这包 - 在System Root Node - 存在，而且它已经找到它在数据库中，但那么当试图插入不在数据库中的Root Node时，它会尝试再次插入System Root Node，这也是它违反约束条件的地方。

这是我用来创建存储库实例代码：

Map<String, String> props = new HashMap<>(); 

props.put(RepositoryFactoryImpl.REPOSITORY_HOME, "jackrabbit"); 
props.put(RepositoryFactoryImpl.REPOSITORY_CONF, "classpath:jackrabbit/repository.xml"); 

Repository repository = JcrUtils.getRepository(props); 

repository.login(new SimpleCredentials("admin", "admin".toCharArray()));

而且我的repository.xml：

任何帮助表示赞赏。

找到了解决办法，但我确定我的配置仍然存在问题，而不是Jackrabbit Oracle支持中的错误。

不管怎样，最后期限是它们是什么，我能得到的一切通过重写OraclePersistenceManager.storeBundle工作：

public class MyPersistenceManager extends OraclePersistenceManager { 

    protected synchronized void storeBundle(NodePropBundle bundle) throws ItemStateException { 
     if (exists(bundle.getId())) { 
      bundle.markOld(); 
     } 
     super.storeBundle(bundle); 
    } 

}

但愿这不只是隐藏抚养了在路上的一个问题。如果有，我会更新。
