Writing Your First Bean CHAPTER 3 In this (Best web design)
Writing Your First Bean CHAPTER 3 In this chapter, we ll get down-and-dirty and write a real working EJB component. Our stateless session bean will be responsible for the mighty task of returning the string Hello, World! to the client. We ll see how to write each of the files that make up this bean and how to access it from clients. This chapter is great for you if you want to discover how to get up and running with EJB quickly. While this may not be the most functional demonstration of the power of EJB, it illustrates the basics of EJB programming and is a useful template for building more complex beans. This will give you the necessary foundation to understand later chapters on entity beans, session beans, and message-driven beans. We encourage you to compile and execute the example code as we go along.
