runtime configuration of hibernate properties though, looks like its

possible so I will settle for seperate persistence.xml files.

Maybe I misunderstood something. You want to set persistent.xml
properties in your test code. Look carefully at setUpClass method.
There are properties set for toplink JPA, but I think you can
replace them with properties for hibernate easily.
The only thing I don't know is which properties are more important:
those placed in persistent.xml or in test code.
I think that's TopLink specific. But it's a good idea and one we've
talked about in the past.
I went ahead and hacked something up here. Now you can override
properties on the persistence-units just as you can override the
properties of <Resource> and <Container> objects.
So with a unit like so:
<persistence-unit name="movie-unit">
<provider>org.hibernate.ejb.HibernatePersistence</provider>
<jta-data-source>movieDatabase</jta-data-source>
<non-jta-data-source>movieDatabaseUnmanaged</non-jta-data-source>
<properties>
<property name="hibernate.hbm2ddl.auto" value="create-drop"/>
<property name="hibernate.dialect" value="mysql"/>
</properties>
</persistence-unit>
You can override it in your test case like so:
Properties p = new Properties();
p.put(Context.INITIAL_CONTEXT_FACTORY,
"org.apache.openejb.client.LocalInitialContextFactory");
p.put("movie-unit.hibernate.dialect", "hsql");
Context context = new InitialContext(p);
So the override format is "<unitName>.<propertyName>=<valueName>"
I've uploaded new 3.1-SNAPSHOTs to the apache snapshot repo [1]. Give
them a try and let us know how it goes.
