我在访问根文件夹时收到 CMISNotFoundException，即使我已经将许多文档上传到存储库。我能够获取存储库 ID，但 getRootFolder 抛出错误

由于 org.apache.chemistry.opencmis.commons.exceptions.CmisObjectNotFoundException 无法获取文件夹：找不到对象

s = d.getSession().session;
p.append("Successfully established session \n");
p.append("id:"+s.getRepositoryInfo().getId()+"\n");
try {
    Folder folder = s.getRootFolder();
    }catch(Exception e) {
           p.append("could not fetch folder due to "+e.toString()+"\n");
    }

创建新存储库后，我现在可以获取根文件夹。但是现在应用 ACLS 我遇到了问题。

  1. L当我尝试将 ACl 应用于根文件夹时，我得到 CmisObjectNotFound 异常。
  2. 当我将 ACL 应用于子文件夹时，它可以工作，但权限未正确应用。我想给 user1 所有权限和 user 2 读取权限。但是对于 user1，现在我什至无法查看文件夹。对于 user2除了下载，我什么都能做。

我已经提到了这个链接sap-link
