    Hi,

    these two messages mean, that DB doesn't support READ_UNCOMMITED transaction isolation level. Clover tries to set this level to achieve faster reading from the database.
    It's not vital and graph initialization goes on.

    There is another problem which causes, that component can't be initialized.
    In this case it was transformation class of DBJOIN component, which wasn't on server CLASSPATH.

    The error handling/reporting will be extended in 2.8.2 version of Clover Server - which should help to find the cause of such problem easier.

    This turned out to be a problem with missing dependencies which didn't surface via the typical ClassNotFound exception.
