In this chapter, were introduced to session beans, and it was explained how NetBeans can help us speed up session bean development. We covered how Enterprise JavaBeans in general, and session beans in particular, allow us to easily implement transaction strategies in our enterprise applications. We also covered how we can implement Aspect-Oriented Programming (AOP) with session beans via interceptors. Additionally, we looked at how session beans can have one of their methods invoked periodically by the EJB container, by taking advantage of the EJB Timer Service. Lastly, we covered how NetBeans can help speed up the implementation of the data access layer of our applications by generating session beans implementing the Data Access Object (DAO) design pattern automatically.
