Sure, but you can make one, right? You've already got the $dbh. Just make a new Rose::DB-derived object and shove the $dbh in there :) If you do this a lot, you can make a helper function for it: $db = make_me_a_db_from($dbh); or even wrap the Manager methods with custom versions that do this for you and then call through to the real versions. > but i tried this...and it worked in an unexpected way-> > > my $dbh= standard DBI handle > $loaded= Object::Manager->get_assets( query=>[params], dbh=> $dbh ); > > it worked. i dont think it should have, but it did. Undocumented! Beware! Although that probably does work for you, the Manager needs a db some way or another. So while it will use your $dbh, it will also call YourObjectClass->init_db to get a Rose::DB-derived object to use. Remember, Rose::DB does more than just provide the $dbh. It also encapsulates database-specific behavior. So your naughty, undocumented example code above relies on YourObjectClass->init_db returning a db object whose driver is the same as your $dbh. When you do it the documented, supported way, you're guaranteed that they'll match because trying to inject a $dbh into a Rose::DB-derived object will cause a fatal error if the drivers don't match. -John ------------------------------------------------------- Using Tomcat but need to do more?
