INTERVIEW QUESTIONS J2EE EJB DETAILS

Question: When are ejbCreate and ejbRemove called on stateless EJBs?

Answer: A. When the stateless beans are created and removed by the EJB container. Note that this does not correspond to calls to create and remove on the stateless home. Depending on your initial-beans-in-free-pool setting, beans may be created by the container during deployment at which point they are placed in the free pool. Aside from during deployment, beans will only be created to service requests when all of the beans in the free pool are in use and the max-beans-in-free-pool limit has not been met. Stateless beans are removed by the EJB container during undeployment.
