Hi,
Yeah this is true that more than one instances of an entity bean can be
there, it is done for performance boost.
And as far as the synchronization of all the instances is concerned, its is
the responsibility of the app server vendor??
I don't think all the available app servers do this..
But Weblogic is one, Inprise is other ..
But for weblogic you have to install SP5.. otherwise there is bug.. for
details see the previous mail on the list..
Correct me if I am wrong..
Thanks,
Rajan

Subject: can multiple instances of an entity bean with the same PK
exist?
Hi everyone,
I was stumped by the following post on TheServerSide:
http://www.theserverside.com:8080/patterns/thread.jsp?thread_id=220#2665
Gal suggests that most ejbServers will load multiple instances of an
entity bean with the same primary key inorder to service multiple clients.
Is this true? Which app. servers do this?
He also suggests that serializeable transactions on these beans
won't
really be serializeable, how is that possible? What does it matter what
concurrency algorith is used, the spec says serializeable transactions must
occur in a serial fashion, so thats all a developer should be concerned with
right?
dazed and confused,
Floyd Marinescu
