tried that one but it didnt work. i even tried using some really weird parameters on that test/bootstrap/META-INF/persistence.properties file to see if the persistence.properties is used but the test finished without any error.
i'm not sure but i dont think the persistence.properties is used. i tried modifying the persistence.xml on ejb/ejbModule/META-INF/persistence.xml (modified the hibernate.hbm2ddl.auto value to create/create-drop) and it did the job.
the only problem now is that same setting is used by both the deploy and test and what i need is to make the deploy use update hbm2ddl while the test should use create or create-drop
btw i'm using jboss 4.2.2 GA, seam 2.0.1 GA and jboss tools 2.0.0 GA
Maybe look at DBUnit with Seam.
