Answer 1

You can try using create = true with url string.

<property name=”hibernate.connection.url”>jdbc:derby:DBUSER;create=true</property>

It creates the standard database specified within the database connection URL Derby system and then connects to it. If the database cannot be created, the error appears in the error log and the connection attempt fails with an SQLException indicating that the database cannot be found.

If the database already exists, creates a connection to the existing database and an SQLWarning is issued.
