This week's book giveaway is in the Cloud/Virtualization forum. We're giving away four copies of Mastering Corda: Blockchain for Java Developers and have Jamiel Sheikh on-line! See this thread for details.
You should find the answer in the HFE book or the spec. But at the top of my head setEntityContext unsetEntityContext ejbActivate ejbPassivate would execute in an "unspecified transaction context" . These are not exposed to the client anyway. Also ejbLoad would be invoked in the transaction context of the calling "business method" ejbStore would be invoked in the transaction context of either the "ejbLoad" or the "ejbCreate" ejbPostCreate would be invoked in the transaction context of ejbCreate These are again not exposed to the client For CMP / BMP entity beans, since they are "CMT" , all the other methods should have a transaction attribute defined, either generically (wildcard) or specifically. Hope this helps
