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
