EJB: How container will maintain synchronization of multiple calls to an entity bean?

radhika743 · 05-11-07, 11:01 AM

How the container will maintain synchronization for multiple calls to the entity bean?

Is it by transactions? Is so , what is the default transaction attribute setting to entity beans?

Can someone please clarify this for me?

Container maintains a pool of entity beans in order to satisfy the mulitple client requests.

in case of Entity beans once the client request is completed. It comes to Instance pool to satisfy next client.Here container maintains a pool of Entity Bean instances to satisfy multiple client requests.
Stateful Session Beans are dedicated to one client.
Once a stateless session bean has finished a method invocation for a client, it can be reassigend to any other EJB object to service a new client.

It is a nice answer.

EJB container itself takes care of synchronization task.so single instance can respond for more than one request simultaneously.

Comments are welcome.
