Does anyone know how to directly access EJB's from a client (Swing or RIA) by passing any session beans?

You cannot use JPA / EntityManager directly from a client (unless you connect directly to the database, or use remote driver).

You can use RMI to access a SessionBean's Remote interface to invoke methods on the server. Those methods could serialize Entity objects, but they will be detached. You will need to merge them back on the server to update the database.
