Caching with periodic updates using EJB 3.1 Singleton and Timer

With the introduction of Singleton beans in EJB 3.1, implementing a cache in the business-tier has become easy. Only one instance of a singleton bean is created per JVM (in case the application server runs in multiple clusters) by the EJB container. The singleton beans also provide other features of EJB – transaction and concurrency management, security, remote access, life cycle callbacks, interceptors and dependency injection.
