EJB 3 in Action, Second Edition

Part 4. Putting EJB into action

In this part you’ll be shown guidelines for putting EJB 3 into action in your company. We’ll first discuss packaging EJBs and entities for deployment to a server in chapter 13. You’ll also learn about the Java EE module system and class loading in EE applications. Chapter 14 introduces web sockets, their relationship to EJBs, and asynchronous business logic execution using the EJB concurrency utilities. You’ll be introduced to different testing strategies in chapter 15, which covers unit and integration testing without the need for deployment to a running server.
