Long description
What do Ford Financial, IBM, and Victoria's Secret have in common? Enterprise JavaBeans (EJB). As the industry standard for platform-independent reusable business components, EJB has just become Sun Microsystem's latest developer certification. Whether you want to be certifiable or just want to learn the technology inside and out, Head First EJB will get you there in the least painful way. And with the greatest understanding. You'll learn not just what the technology -is-, but more importantly, -why- it is, and what it is and isn't good for. You'll learn tricks and tips for EJB development, along with tricks and tips for passing this latest, very challenging Sun Certified Business Component Developer (SCBCD) exam. You'll learn how to think like a server. You'll learn how to think like a bean. And because this is a Head First book, you'll learn how to think about thinking. Co-author Kathy Sierra was one of Sun's first employees to teach brave, early adopter customers how to use EJB. She has the scars. But besides dragging you deep into EJB technology, Kathy and Bert will see you through your certification exam, if you decide to go for it.;And nobody knows the certification like they do - they're co-developers of Sun's actual exam! As the second book in the Head First series, Head First EJB follows up the number one best-selling Java book in the US, Head First Java. Find out why reviewers are calling it a revolution in learning tough technical topics, and why Sun Chairman and CEO Scott McNealy says, "Java technology is everywhere...if you develop software and haven't learned Java, it's definitely time to dive in "Head First." And with Head First book, you don't even have to feel guilty about having fun while you're learning; it's all part of the learning theory. If the latest research in cognitive science, education, and neurobiology suggested that boring, dry, and excruciatingly painful was the best way to learn, we'd have done it. Thankfully, it's been shown that your brain has a sense of style, a sense of humour, and a darn good sense of what it likes and dislikes.;In Head First EJB, you'll learn all about: Component-based and role-based development The architecture of EJB, distributed programming with RMI Developing and Deploying an EJB application The Client View of a Session and Entity bean The Session Bean Lifecycle and Component Contract The Entity bean Lifecycle and Component Contract Container-managed Persistence (CMP) Container-managed Relationships (CMR) EJB-QL Transactions Security EJB Exceptions The Deployment Descriptor The Enterprise Bean Environment in JNDI Programming Restrictions and Portability Patterns and Performance for EJB The book includes over 200 mock exam questions that match the tone, style, difficulty, and topics on the real SCBCD exam. See why Kathy and Bert are responsible for thousands of successful exam-passers-- "The Sun certification exam was certainly no walk in the park, but Kathy's material allowed me to not only pass the exam, but Ace it!" --Mary Whetsel, Sr. Technology Specialist, Application Strategy and Integration, The St.;Paul Companies "Kathy Sierra and Bert Bates are two of the few people in the world who can make complicated things seem damn simple, and as if that isn't enough, they can make boring things seem interesting." --Paul Wheaton, The Trail Boss, javaranch.com "Who better to write a Java study guide than Kathy Sierra, reigning queen of Java instruction?
