It's up to each app server to decide how you can check the deployment status.

I think it'd be good, though, if OpenJPA had a setting or an API call
to ensure that everything was up and running once the factory was
created. Currently, that API call is:

emf.createEntityManager().close();

It'd be nice at least to provide either a declarative (setting)
approach for that, or an API that does just that but sounds a bit less
hacky. We could then potentially optimize the API at a later time.

Joshua,

If you deploy an application into an appserver, and your persistence.xml
contains the openjpa.jdbc.SynchronizeMappings property, the tables will be
created on the 1st emf.createEntityManager() call (or injection of EM that does
the same in the background), i.e. on every redeploy or server restart.

It's up to each app server to decide how you can check the deployment status.
