The Java EE 6 Tutorial
Java Coffee Cup logoSession beans provide a simple but powerful way to encapsulate business logic within an application. They can be accessed from remote Java clients, web service clients, and components running in the same server.
In Chapter 23, Getting Started with Enterprise Beans, you built a stateless session bean named ConverterBean. This chapter examines the source code of four more session beans:
CartBean: a stateful session bean that is accessed by a remote client
CounterBean: a singleton session bean
HelloServiceBean: a stateless session bean that implements a web service
TimerSessionBean: a stateless session bean that sets a timer
