In my existing JBoss 6 app I'm using @Cache("No Passivation") which was implemented in jboss-ejb3-ext-api.jar. I was using this annotation for a stateful singleton. Is there a similiar solution in JBoss 7?
Passivation is not part of the EJB lite, so AS7.0 does not support it, it will be supported in 7.1, which will provide some way of controlling it.
