2.10. Managing EJB Using Bean Pooling
The container cannot handle an unlimited number of EJB, therefore the container must pool the resources and share them across users. Each EJB, when deployed, specifies the number of instances to pool and reuse. EJB are not lightweight objects that can be created and destroyed when necessary. They are heavy objects that take considerable resource to create and destory. Therefore, the application server will manage a pool of EJB that users can use throughout the application. By having this pool, the application server can handle more requests since it does not have to spend time creating and destroying objects.
