You should be obtaining your EJBs via a proxy object, looked up through JNDI...please post your view code? Was expecting something like: at Proxy$x.getAlertsFromEntity() VO/TO = Value Object / Transfer Object. Serializable POJOs without any session-specific information (read: Hibernate) associated with them, intended for holding data for safe shipping between layers.
