Hi, We managed to work around issue JCR-1558 by re-registering the custom namespaces on the cluster node start up.
Just to be entirely clear on this, the repository.xml file has 3 FileSystems defined: - for repository - for workspaces - for versioning Does each cluster node need its own FileSystem for *all* of these, or only the repository and versioning? Finally, all the clustering examples we've come across use the LocalFileSystem. Is there a particular reason for this? We'd like to use the DBFileSystem - is this likely to cause us any problems? Thanks for everything. Dipu On Wed, Apr 1, 2009 at 3:30 PM, Dipu <[email protected]> wrote: > Hi Thomas, > > Thank you for the rapid reply.
