I am running tests using Arquillian, JBoss, JPA/Hibernate, H2 DB and Maven. In my test persistence.xml file I have:
<property name="hibernate.hbm2ddl.auto" value="create-drop" />
<property name="hibernate.show_sql" value="true" />
For now I have a single User class mapped to a 'users' table via Hibernate annotations.
Things are almost working. The problem is Hibernate is trying to execute:
drop table my_schema.users if exists
But the schema, 'my_schema' doesn't exist so it fails (I'm running against an in-memory DB after all).
How do I get hibernate to execute the 'create schema my_schema' step that it seems to be forgetting?
Update: The messages I see from Hibernate:

I found the answer in another SO Question.
When defining the connection URL to the DB, this needs to be added: "INIT=CREATE SCHEMA IF NOT EXISTS ". So the full URL in the persistence.xml file looks like:
<connection-url>jdbc:h2:mem:test-db;DB_CLOSE_DELAY=-1;INIT=CREATE SCHEMA IF NOT EXISTS ccmc</connection-url>
where ccmc is the name of the schema to be created. Param DB_CLOSE_DELAY is unrelated with the problem and can be safely omited regarding this matter.
