Your assessment is confirmed by the EJB 2.0 specification.
Chapter 10 Entity Bean Component Contract for Container-Managed Persistence 10.5 Instance life cycle contract between the bean and the container 10.5.5 Operations allowed in the methods of the entity bean class Page 179 - Table 4.
However you may want to invest some time in updating the information in your copy of HF EJB with the information found in the confirmed errata (that one is already covered). And if you find something else check the unconfirmed errata. [ October 13, 2005: Message edited by: Peer Reynders ]
