It depends on what version of Jackrabbit you are using - I had errors like this in the past and the solution was a fix on the CVS. Make sure you get the latest version and in case the error keeps poping up take the issue with Jackrabbit.
In most cases, the problem comes from the fact that the jcr session you are using is closed.
Thank you! I resolved the problem.
Could you tell me when to release the next springmodules including JCR?
Basically, the next release of spring modules will include the JCR along with a lot of new modules. Hopefully, the release will happen in the near future (1 months or so) - the main hold up being the infrastructure refactoring.
There are a number of cool features right now on the CVS and the entire team wants them released to the public.
