Hi, Just recently there was a discussion about getting the unique identifier for a binary value. I created an issue: https://issues.apache.org/jira/browse/JCR-1892
> I am currently using the XMLPersistenceManager. You should consider using a bundle database persistence manager. See also http://wiki.apache.org/jackrabbit/PersistenceManagerFAQ - XMLPersistenceManager: If the JVM process is killed the repository might turn inconsistent; Status: obsolete, mature > Listed below is the code I've used to obtain file paths. One problem is > that BLOBInResource does not have a getFileSystem() method - is there a > reason for this? BLOBInResource is not used if you use a data store. I would consider using a data store. Unfortunately, you can't get the identifier from the BLOBInDataStore. But using Jackrabbit internal classes directly is anyway problematic as they change in future versions. Regards, Thomas
