POJOs In Action

Lightweight Frameworks & Enterprise Applications.

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. Use of Plain Object Java Objects (POJOs), the intentionally fancy name for regular Java objects, is a common thread of the new technologies. This book describes how to develop applications using POJOs and their supporting technologies. It describes how to make key design decisions when developing business logic using POJOs, including how to organise 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.
