Number of Entity Beans
posted 13 years ago
Entity beans are created only when a client requests it. The app server will not automatically instantiate 10000 entity beans on startup. The number of entity beans living in memory depends on server resources and to a certain extent the ejb container implementation. Using instance pooling and swapping the container will be able to use fewer instances to represent a large number of underlying data records. That is the beauty of EJB technology.
