I'm getting CMISNotFoundException while accessing the root folder even though i already have many documents uploaded to the repository.I'm able to fetch the repository id but getRootFolder throws error
could not fetch folder due to org.apache.chemistry.opencmis.commons.exceptions.CmisObjectNotFoundException: Object not found
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");
}
I'm able to get the root folder now after creating a new repository.But now for applying ACLS i'm facing problem.
- LWhen i try to apply ACl to the root folder i get CmisObjectNotFound exception.
- When i apply ACL to subfolders, it workds but the permission is not applied correctly.I want to give user1 all the permission and user 2 read permission.But for user1 , now i'm not able to even view the folder.And for user2 i'm able to do everything except download.
I have referred to this link for doing so sap-link
