[b]Glassfish config (domain.xml):[/b]
<ejb-container cache-idle-timeout-in-seconds="600" cache-resize-quantity="1" commit-option="B" [b]max-cache-size="1" [/b]max-pool-size="1" pool-idle-timeout-in-seconds="600" pool-resize-quantity="8" removal-timeout-in-seconds="5400" session-store="${com.sun.aas.instanceRoot}/session-store" steady-pool-size="0" victim-selection-policy="fifo">...
Note here I changed the max-cache-size to 1, so that theoretically the 2nd client call will create another stateful session bean, and get the first passivated. However, the output was:
INFO: CountCallbacks.construct()
INFO: CountBean.set(0)
INFO: CountBean.count(0->1)
INFO: CountCallbacks.construct()
INFO: CountBean.set(1)
INFO: CountBean.count(1->2)
INFO: CountCallbacks.construct()
INFO: CountBean.set(2)
INFO: CountBean.count(2->3)
INFO: CountBean.count(1->2)
INFO: CountBean.remove()
INFO: CountCallbacks.destroy()
INFO: CountBean.count(2->3)
INFO: CountBean.remove()
INFO: CountCallbacks.destroy()
INFO: CountBean.count(3->4)
INFO: CountBean.remove()
INFO: CountCallbacks.destroy()
None of the PrePassivate or PostActivate invoked. Is this a bug in Glassfish v2.1 b60e?
