Re: OJB JDO & multiple database

Hi,

Is there a way how I can simultaneously use multiple databases from OJB 
JDO ?

OJB allows us to specify multiple jdbc-connection in the database 
repository but I don't know how to choose a jdbc-connection via the OJB 
JDO api ?
Currently our JDO solution does only work against the default 
Persistencebroker. So there is currently no way to use more than one db 
with simple API calls.

I wonder if the following JDO code works with OJB :

            PersistenceManagerFactory pmf =
                (PersistenceManagerFactory) 
Class.forName(pmf_class).newInstance();
            pmf.setConnectionURL(db_url);
            pmf.setConnectionDriverName(db_driver);
            if (user_name != null)
                pmf.setConnectionUserName(user_name);
            if (password != null)
                pmf.setConnectionPassword(password);

Can someone tell me if these properties are used ?
No these methods are are not used in our solution.

If not, what is used and how configure it?
We are using the settings of the default PersistenceBroker in the 
repository.xml.
So you can change the db url by changing the OJB Metadata at runtime 
through the o.a.ojb.broker.metadata.MetaDataManager.

cheers,
Thomas
Thanks.
