It was discussed in #3994#note-9:

schema files are not included in resulting jar (and probably tigase-server needs to be updated as well, probably same solution as in tigase-pubsub case);

This is starting to be an issue. We need to implement this automatic update for DB schema mechanism.

OK, having automatic updater will be handy, but... this is separate issue - we need to transfer schema from component to main tigase server distribution packages, hence we should include it in the resulting jar and then unpack it.

but we got sidetracked with documentation
