at least a changelog would help.
Probably the default xml file as well

|Jim,
|
|I'm in total agreement here. Serialized access is really only good for
|synchronized caching.
|
|Yes, for commit option 'B' and 'C' there is a way to duplicate instances of
|entity beans. Unfortunately, this code has a major bug in it so you would
|have to go to CVS and get latest from Branch_2_4.
|
|How to enable it?
|
|1. In standardjboss.xml(or your own container-configuration), change
|<commit-option> to B or C.
|2. Also change the <locking-policy> from QueuedPessimisticEJBLock to
|MethodOnlyEJBLock.
|3. Also change EntityInstanceInterceptor to EntityMultiInstanceInterceptor.
|4. Also change EntitySynchronizationInterceptor to
|EntityMultiInstanceSynchronizationInterceptor.
|
|I'm sorry that this is not documented.
|
|Also, unfortunately, this stuff will not work with commit-option 'A' since
|no caching is done. This can be improved later.
|
|Regards,
|
|Bill
