Dear all, Today I tried using entity-transaction with Toplink as the persistence provider and it didn't work because of ClassCastException. When I digged in to the Seam source, it looks like that entity-transaction is tightly coupled with Hibernate. Is this true? I hope I'm wrong about this. Is there any reason why does the entity-transaction component is only supported for Hibernate?
