Hello,
Is it possible to change the database in Java EE based on values read in
from a config file? How can I create an EntityMangerFactory based on
the new database parameters?
I know this can be done in Java SE, by creating an EntityManagerFactory
with a map containing user, password, database url, and driver.
What about Java EE? I know the container is responsible for creating
the EntityManagerFactory based on the persistence.xml file it finds
packaged in the war file. Is it advisable to create a new
EntityManagerFactory in Java EE? Is it possible?
Thanks in advance.
PD
