The standard platform for enterprise application development has beenEJB but the difficulties of working with it caused it to becomeunpopular. They also gave rise to lightweight technologies such asHibernate, Spring, JDO, iBATIS and others, all of which allow thedeveloper to work directly with the simpler POJOs. Now EJB version 3solves the problems that gave EJB 2 a black eye-it too works withPOJOs. "POJOs in Action" describes the new, easier ways to developenterprise Java applications. It describes how to make key designdecisions when developing business logic using POJOs, including how toorganize and encapsulate the business logic, access the database,manage transactions, and handle database concurrency. This book is anew-generation Java applications guide: it enables readers tosuccessfully build lightweight applications that are easier to develop,test, and maintain.
