It depends on the Application Server you are using. Weblogic 5.1 - One instance of EJBObject for every unique primary key of Entity bean in a single JVM. - known as container pessimistic locking. Weblogic 6.1 - There could be multiple instance of EJBObject for every unique primary of Entity bean in a single JVM. - container Optimistic locking.
Almost all other application server implement container Optmisitic locking. As container perssimistic locking might cause deadlock and forcing container to abort transaction.

I'm pretty confused as to whether same instance of entity bean object in the container can be bound with more than on EJBObject (and hence available to more than one clients) at the same time. There can be multiple instances of Entity bean representing the same data in DB to serve different clients but is above statement also holds true at times ?
