In the past, developers built enterprise Java applications using EJB technologies that are excessively complex and difficult to use. Often EJB introduced more problems than it solved. There is a major trend in the industry towards using simpler and easier technologies such as Hibernate, Spring, JDO, iBATIS and others, all of which allow the developer to work directly with the simpler Plain Old Java Objects or POJOs. Now EJB version 3 solves the problems that gave EJB 2 a black eye--it too works with POJOs. POJOs in Action describes the new, easier ways to develop enterprise Java applications. It describes how to make key design decisions when developing business logic using POJOs, including how to organize and encapsulate the business logic, access the database, manage transactions, and handle database concurrency. This book is a new-generation Java applications guide: it enables readers to successfully build lightweight applications that are easier to develop, test, and maintain.
