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
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? Kathy Sierra has done it again. Here is a study guide that almost guarantees you a certification!"--James Cubetta, Systems Engineer, SGI.

Chapter 1 : Intro to EJB: Welcome to EJB What is EJB all about? What does EJB really give me? No more vendor lock-in! How does it all work? Behind the scenes... Beans come in three flavors Session beans can be stateless or stateful Example: The Advice Guy bean Five things you do to build a bean: EJB Roles and Responsibilities Tutorial: Organize your project directory Compile the two interfaces and the bean class Start the server You’ll see something like this Start deploytool you’ll see something like this Make a new Application Name and save the new application What you’ll see after you create and name the application Now let’s make the new enterprise bean (the ejb-jar and the DD) Now we’re in the really cool New Enterprise Bean Wizard Create the new ejb-jar Add the three class files (including their package directory) to the JAR Confirm that you added ONLY the package directory and the class files Make it a Stateless Session bean Tell it which of the three class files in the JAR is the actual BEAN class Tell it which is the Home interface, and which is the Component interface Verify everything on this screen! You’re done, click Finish Meanwhile back on the main deploytool screen... Run your bean through the deploytool verifier Close your eyes and click OK Whew! No failed tests Time to Deploy Make it Return a Client Jar Give it a name, so clients can look it Up Watch the progress bars go up, then celebrate Now you’ll see the AdviceApp inside the server Now all we need is a client... Organizing your project directory for the client Coffee Cram: Mock Exam Coffee Cram: Mock Exam Answers Chapter 2 : Architectural Overview: EJB Architecture You remember this picture... Making a remote method call There’s a “helper” on the server as well... What about arguments and return values? What really gets passed when you pass an object to a remote method? Passing a Remote object through a remote method call What must the Remote object and the stub have in common? The client calls business methods on the stub through the Remote business interface How EJB uses RMI The Remote object is not the bean, it’s the bean’s bodyguard—the EJBObject The Component interface Who writes the class that really DOES implement the component interface? In other words, who makes the EJBObject class? Who creates what? The bean Home Architectural overview: Session beans Architectural overview: Entity beans Architectural overview: Creating a Stateful Session bean Architectural overview: Creating a Stateless Session bean Who creates the stateless session bean, and when? Stateless session beans are more scalable Architectural overview: Message-driven beans Chapter 3 : The Client View: Exposing Yourself What the client really wants It all starts with the home interface How a client uses a session bean: create, use, and remove But first, we have to get a home interface reference Let’s take another look at the complete client code Just when you thought a simple cast would be enough... But NO. You have to narrow the object as well! OK, I’ll bite. Why can’t you just do a plain old cast? PortableRemoteObject.narrow() Writing the Remote home interface for a session bean Remote home interface examples for session beans But enough about the home... let’s talk about the EJB object. The component interface. The thing you REALLY want. Imagine what else you might want to do with your EJB object reference... Thankfully, we’ve got handles isIdentical? A bean’s client interfaces can be local Which methods make sense for the local client interfaces? When you think handle, think Remote Who needs EJBMetaData when you’ve got reflection? Do you need isIdentical() when there’s equals()? Why so many remove methods? Comparing Remote vs. Local interfaces Writing the local client interfaces You can have both a Remote and local client view for a bean, but you probably won’t. Exceptions in client interfaces: what the client might get Local client code What has to change inside the bean class? Arguments to Remote vs. local methods Coffee Cram: Mock Exam Coffee Cram: Mock Exam Answers Chapter 4 : Session Bean Lifecycle: Being a Session Bean Exploring the session bean lifecycle You remember how it all works, right? There’s obviously more to the bean’s lifecycle than just creation and business methods... Container Callbacks, for the special moments in a bean’s life... Container Callbacks come from TWO places Implementing the container callbacks We have to look at the transitions Bean Creation: when an object becomes a bean Bean things you can do during creation Bean Use: what happens AFTER creation... Bean things you can do within business methods Passivation: a stateful bean’s chance at scalability... Your job for passivation: make your state passivatable! Bean things you can do in ejbActivate() and ejbPassivate() Bean Removal: when beans die Complaints about bean removal Bean things you can do in ejbRemove() Implementing the AdviceBean as a stateFUL bean AdviceStatefulBean code AdviceStatefulBean CLIENT code Deploying a stateful bean Compared to stateful beans, stateless beans have a simple life Bean things you can do from stateless bean methods Writing a Session Bean: your job as Bean Provider SessionContext Coffee Cram: Mock Exam Coffee Cram: Mock Exam Answers Chapter 5 : Entity Bean Intro: Entities are Persistent What’s an entity bean? Entities vs. Entity Beans Entity beans from the client’s point of view A very simple Customer entity bean An entity bean’s client view Entity bean Remote component interface Entity bean Remote component interface Entity bean Remote home interface What does the client really want from an entity bean home? Entity bean Remote home interface When finders have a dark side... Home business methods to the rescue Session bean create() vs. entity bean create() Session bean remove() vs. entity bean remove() Entity/bean/instance death Entity bean client view Coffee Cram: Mock Exam Coffee Cram: Mock Exam Answers Chapter 6 : Bean/Entity Synchronization: Being an Entity Bean The real power of entity beans is synchronization The only question is WHO does the work when it’s time to synchronize Container-managed vs. bean-managed persistence A brief history on the evolution of CMP 2.0 The EntityBean interface adds three new container callbacks (including two just for synchronization) Even the methods that are the same, don’t behave the same But wait... there’s more! Entity beans have new home container callbacks, too Writing a CMP entity bean: make it abstract You put three kinds of things in your bean class: PLUS... (ok, that’s four things...) Virtual fields are NOT instance variables! Complete code for the CustomerBeanCMP class So how DID the client get a reference to the EJB object for #28? Bean things you can do during entity construction: Object identity: the primary key Bean things you can do during entity creation: Bean things you can do in home business methods Bean things you can do during activation and loading Bean things you can do during passivation and storing Coffee Cram: Mock Exam Coffee Cram: Mock Exam Answers Chapter 7 : Entity Relationships: When Beans Relate Beanifying your movie database But we don’t want to think in TABLES We want to think in CLASSES We need relationships between the Movie bean and the Director bean Why should the Director be a bean? Why can’t it just be data? Relationships and multiplicity Multiplicity in Bean Classes Multiplicity affects return type! Defining virtual fields for persistent data fields and relationship fields Defining your “abstract persistence schema” (virtual fields aren’t enough) Persistent CMP fields in the DD Using relationships in your code Defining relationships in your abstract persistence schema (in the DD) Mapping from abstract schema to a real database Coffee Cram: Mock Exam Coffee Cram: Mock Exam Answers Chapter 8 : Message-Driven Beans: Getting the Message Imagine this scenario... Too bad these guys aren’t message-driven beans Message-driven bean class Writing a message-driven bean: your job as Bean Provider Notice something missing from the code? Topics and Queues Only ONE bean per pool gets a copy of a topic message With a queue, only one bean gets the message. Period. MessageDrivenContext MessageDrivenContext What if something goes wrong? Message acknowledgement That’s all well and good, but let’s go back and see how our earlier scenario ended... Think about it. Coffee Cram: Mock Exam Coffee Cram: Mock Exam Answers Chapter 9 : EJB Transactions: The Atomic Age The ACID test Distributed transactions: two-phase commit How it works in EJB Some transactions don’t propagate How do I make (or get) a transaction? Transaction-related methods are in two interfaces Making a BMT transaction Call stack of the checkOut() method Things you must NOT do with BMT What does it mean to suspend a transaction? The UserTransaction interface setRollbackOnly() setRollbackOnly() lives in TWO interfaces getRollbackOnly() BMT beans use getStatus() instead of getRollbackOnly() BMT can be a really BAD idea. BMT hurts bean reuse Container-managed transactions How attributes work Transaction attributes that require a transaction Transaction attributes that do not require a transaction These are the methods you MUST mark with an attribute (for a CMT bean) “Unspecified Transaction Context” Burn these in Marking transactions in the DD DD example for CMT More DD examples for CMT Summary of Bean-managed demarcation Entity beans have ejbLoad() to stay synchronized, even if the transaction rolls back. Session Synchronization SessionSynchronization “special moments” Coffee Cram: Mock Exam Coffee Cram: Mock Exam Answers Chapter 10 : Exceptions in EJB: When beans go bad What can go wrong? Remember, Java exceptions can be checked or unchecked It’s all about expectations... In EJB, exceptions come in two flavors: application and system With an Application Exception, the Container will... With a System Exception, the Container will... Warning! RemoteException is checked, but not expected! RemoteException goes to remote clients EJBException goes to local clients Bean Provider’s responsibilities The Container’s responsibilities The five standard EJB application exceptions The five standard application exceptions from the client’s point of view Common system exceptions Common system exceptions Scenarios: what do you think happens? Scenario Summary Coffee Cram: Mock Exam Coffee Cram: Mock Exam Answers Chapter 11 : Security in EJB: Protect Your Secrets Imagine you’re writing a payroll application... What can you do? How to do security in EJB The Application Assembler’s job: access control Defining the roles Defining the roles... a better way Defining the method permissions Defining the method permissions Method permissions interact with one another as a union! Watch out for <unchecked/> The Deployer’s job: mapping actual humans to abstract roles Principals and Roles, Users and Groups Class-level vs. instance-level security Using programmatic security to custom-tailor a method The problem with isCallerInRole()... Map declarative security roles to the programmer’s hard-coded (fake) roles Use <run-as> security identity to pretend someone else is calling... Security context propagation with <run-as> Coffee Cram: Mock Exam Coffee Cram: Mock Exam Answers Chapter 12 : A Bean’s Environment: The Joy of Deployment A bean’s special place- java:comp/env But it’s not per bean instance... It’s per bean home It’s simple... if the programmer puts a made-up JNDI name in code, he has to announce that to the deployer in the DD. Bean Provider and Application Assembler responsibility for the Deployment Descriptor Deployer responsibility for the Deployment Descriptor Remembering who does what Now let’s look at the bean’s runtime environment Which APIs does EJB 2.0 guarantee? What MUST be in an ejb-jar?

Ethernet is a core networking technology used by every high tech business. While the basic protocols have changed little, new options such as Fast Ethernet and Gigabit Ethernet have increased the complexity of the topic.
Ethernet has been the flavor of choice for networking administrators since the early 1980s because of its ease of use and scalability. Written by one of the foremost experts on Ethernet standards and configuration, Charles E. Spurgeon, Ethernet: The Definitive Guide includes everything you need to know to set up and maintain an Ethernet network. Ethernet: The Definitive Guide teaches you everything you need to know about the IEEE 802.3 Ethernet standard and its protocols. The book is logically separated into five parts:
Introduction to Ethernet provides a tour of basic Ethernet theory and operation, including a description of Ethernet frames, operation of the Media Access Control (MAC) protocol, full-duplex mode and auto-negotiation.
Ethernet Media Systems is the heart of the book. This sectionof Ethernet: The Definitive Guide shows you how to build media-specific Ethernet networks, from a basic 10BASE-T Ethernet offering 10 Mbps over twisted-pair cables, to an advanced 1000BASE-X Gigabit Ethernet, providing up to 1 Gbps of data transfer over fiber optic cables.
Building Your Ethernet System teaches you how to build twisted-pair and fiber optic media segments, as well as how to build your Ethernet using repeaters and hubs.
Performance and Troubleshooting is divided into two chapters. The first describes both the performance of a given Ethernet channel, as well as the performance of the entire network system. The second includes a tutorial on troubleshooting techniques and describes the kinds of problems network administrators are likely to encounter.
The last part of the book includes a complete glossary of terms used throughout the book, a resource list, descriptions of thick and thin coax-based Ethernet systems, a guide to AUI equipment installation and configuration, and a listing of troubleshooting numbers. This book is the definitive guide for anyone wanting to build a scalable local area network (LAN) using Ethernet.

Unlike some operating systems, Linux doesn’t try to hide the important bits from you-it gives you full control of your computer. But to truly master Linux, you need to understand its internals, like how the system boots, how networking works, and what the kernel actually does. In this completely revised second edition of the perennial best seller How Linux Works, author Brian Ward makes the concepts behind Linux internals accessible to anyone curious about the inner workings of the operating system. Inside, you’ll find the kind of knowledge that normally comes from years of experience doing things the hard way. You’ll learn: How Linux boots, from boot loaders to init implementations (systemd, Upstart, and System V) How the kernel manages devices, device drivers, and processes How networking, interfaces, firewalls, and servers work How development tools work and relate to shared libraries How to write effective shell scripts You’ll also explore the kernel and examine key system tasks inside user space, including system calls, input and output, and filesystems. With its combination of background, theory, real-world examples, and patient explanations, How Linux Works will teach you what you need to know to solve pesky problems and take control of your operating system.
