Hello,

I want hibernate to drop all tables an recreate them on startup.
For this purpose hibernate proposes following routine:

<property name="hibernate.hbm2ddl.auto">create</property>

The problem is, that this does not work if my entities contail Many-To-Many associations with generated join tables. (same for parent-child association)
Reason is as far I can tell, that hibernate
1. removes all FK constraints of the entities
2. drops all entity tables
3. removes all FK constraints of generated join tables
4. drops the join tables

---> The problem is, that this will result in errors at 2., because 3. is not removed yet.

My workaround: drop and then create whole database direct with sql / mysql

Is there another possibile workaround with Hibernate? I dont / can't use my workaround effectively on a server.
