Try using JBossTransactionManagerLookup... not sure why you have it commented out.

<property name="hibernate.transaction.manager_lookup_class" value="org.hibernate.transaction.JBossTransactionManagerLookup" />

Next, set this to validate if the tables are already created previously :

<property name="hibernate.hbm2ddl.auto" value="validate" />

Good luck
