Need help: Jackrabbit file deletion doesnot free disk space.

Hi,

We are using Jackrabbit with Derby database as file system.
We are deleting nodes using the jcr api and the nodes are deleted successfully. Since we get
an ItemNotFoundException when we fetch them thereafter.

But if we check the disk space, it still shows the same amount of space occupied.
We are facing space issues on our server and are trying to delete old files to overcome the
issue.

Please advice on the way, the space can be recovered on file deletion from jackrabbit.
Also, please share how the deletion mechanism works, for knowledge purposes.

Thanks.

https://issues.apache.org/jira/browse/JCR-1496 might be helpful.

Imho that is quite a lot of hoops to jump through to get at a
SessionImpl object though and without that bug report I might not have
figured it out either.

Kind regards,

Thanks Jukka.

I have referred to the link provided by you. 
I am using rmi repository (URLRemoteRepository) and while implementing the Data Store Garbage Collection, I need JackrabbitRepository.
Am now stuck with the following issue:

'java.lang.ClassCastException: org.apache.jackrabbit.rmi.repository.URLRemoteRepository cannot be cast to org.apache.jackrabbit.api.JackrabbitRepository' 

I had a look at the class hierarchy but cannot find any way out.
