Hello Wiberto, I would need to do something similar, where I would need to make a user specific connection to Oracle when the user logs in to the application. Can you please post the relevant pieces of code ? Thx in advance !

Then in the entity class I would specify the component to use when injecting the EntityManager. | | Let me know if this is what you want I can post an example.
