Hi,

my JPA, Hibernate, JBoss application is working so far. I created in my test database the db structure manually.
Now I added property "hibernate.hbm2ddl.auto" with value "update".

On JBoss startup I get an exception "java.lang.UnsupportedOperationException: The application must supply JDBC connections".

I only know on the 1st request to my ejb which database is requested. This is done with a convention on the data source name. So the schema export can only be done I think on this 1st request. At this time the schema export is tried on JBoss startup. I create and manage the EntityManagerFactory on my own, because I have read this is the trigger when the schema export is done.
How can I disable the schema export on startup?

Exception:
