EJB 3.0 has simplified the development of EJBs with an annotations-based API that eliminates the use of remote/local interfaces, home/local home interfaces, and deployment descriptors. A number of other books are available on EJB 3.0, but none covers EJB 3.0 support in Oracle Fusion Middleware 11g, which is one of the leaders in the application server market. This is the first book that covers all aspects of EJB 3.0 database persistence development using Oracle Fusion Middleware technology. It covers all the best practices for database persistence ensuring that your applications are easily maintainable. Leaving theory behind, this book uses real-world examples to guide you in building your own EJB 3.0 applications that are well integrated with commonly used Java EE frameworks. The book gets going by discussing the new features in the EJB 3.0 specification. As some readers may still be using EJB 2.0, the book explains how to convert your EJB 2.0 entity beans to EJB 3.0. It then goes on to discuss using EJB 3.0 database persistence with JDeveloper, WebLogic Server, and Enterprise Pack for Eclipse, the main Java EE components of Oracle Fusion Middleware 11g. The book also covers EJB 3.0 relationships and integrating EJB 3.0 relationships with JSF user interfaces. EJB 3.0 database persistence with some of the commonly used frameworks such as ADF Faces, AJAX, and Web Services is also discussed in the book. It uses the integrated WebLogic Server 11g in some of the chapters and the standalone WebLogic Server in other chapters. While JDeveloper is the primary Java IDE used in the book, one of the chapters is based on the Oracle Enterprise Pack for Eclipse. By the time you reach the end of this book, you will be well-versed with developing EJB 3.0 applications using the different Java EE components of Oracle Fusion Middleware 11g. A practical guide illustrated with examples for developing EJB 3.0 applications integrated with commonly used Java EE frameworks such as JSF, Web Services, Ajax, and ADF Faces What you will learn from this book Explore the new features in the EJB 3.0 specification Convert an EJB 2.0 entity bean to EJB 3.0 in JDeveloper Create EJB 3.0 entity beans from database tables automatically in JDeveloper Implement EJB 3.0 database persistence with JDeveloper, WebLogic Server, and Enterprise Pack for Eclipse Wrap an entity bean with a session bean Build a client for an EJB 3.0 entity bean application Develop an ADF Faces user interface (UI) for entity beans Create EJB 3.0 entity relationships Design JSF UIs for EJB 3.0 entity relationships Integrate EJB 3.0 database persistence with an AJAX user interface (UI) Build EJB 3.0 Web Services from entity beans Approach This is a practical, tutorial-style book that includes many examples that demonstrate how to develop EJB 3.0 database persistence applications with Oracle Fusion Middleware 11g.

In Detail

Every day, architects and developers are asked to solve specific business problems in the most efficient way possible using a broad range of technologies. Packed with real-world examples of how to use the latest Microsoft technologies, this book tackles over a dozen specific use case patterns and provides an applied implementation with supporting code downloads for every chapter.

In this book, we guide you through thirteen architectural patterns and provide detailed code samples for the following technologies: Windows Server AppFabric, Windows Azure Platform AppFabric, SQL Server (including Integration Services, Service Broker, and StreamInsight), BizTalk Server, Windows Communication Foundation (WCF), and Windows Workflow Foundation (WF). This book brings together - and simplifies - the information and methodology you need to make the right architectural decisions and use a broad range of the Microsoft platform to meet your requirements. Throughout the book, we will follow a consistent architectural decision framework which considers key business, organizational, and technology factors.

The book is broken up into four sections. First, we define the techniques and methodologies used to make architectural decisions throughout the book. In Part I, we provide a set of primers designed to get you up to speed with each of the technologies demonstrated in the book. Part II looks at messaging patterns and includes use cases which highlight content-based routing, workflow, publish/subscribe, and distributed messaging. Part III digs into data processing patterns and looks at bulk data processing, complex events, multi-master synchronization, and more. Finally, Part IV covers performance-related patterns including low latency, failover to the cloud, and reference data caching.

Expert assessment and implementation guidance across 13 Enterprise scenarios

Approach

The book consists of a set of business scenarios and corresponding solution critiques. Each "use case" chapter is made up of a problem description, assessment of implementation options, and the selection of the ideal solution candidate. We then construct the solution using the chosen Microsoft technology.

Who this book is for

This book is for architects, developers, and managers who need to improve their knowledge of the Microsoft application platform. This book will appeal to anyone who wants to get up to speed on selecting the most appropriate platform for a particular problem. Consultants and executive leadership will also find significant value in this book. A good understanding of the general Windows platform and development technologies would be helpful.

In Detail

SOA is about architecture, not products and SOA enables you to create better business processes faster than ever. While BizTalk Server 2009 is a powerful tool, by itself it cannot deliver long-lasting, agile solutions unless we actively apply tried and tested service-oriented principles.

The current BizTalk Server books are all for the 2006 version and none of them specifically looks at how to map service-oriented principles and patterns to the BizTalk product. That's where this book fits in. In this book, we specifically investigate how to design and build service-oriented solutions using BizTalk Server 2009 as the host platform.

This book extends your existing BizTalk knowledge to apply service-oriented thinking to classic BizTalk scenarios. We look at how to build the most reusable, flexible, and loosely-coupled solutions possible in the BizTalk environment. Along the way, we dive deeply into BizTalk Server's integration with Windows Communication Foundation, and see how to take advantage of the latest updates to the Microsoft platform. Chock full of dozens of demonstrations, this book walks through design considerations, development options, and strategies for maintaining production solutions.

Design and build flexible, reusable, and loosely-coupled SOA solutions with BizTalk Server 2009

Approach

This book takes a hands-on approach to explain and present ways to use BizTalk Server 2009 in a service-oriented fashion. Written much like the author's blog, this book does not direct your every mouse click and keyboard stroke, but rather identifies the problem being solved, and includes the code snippets and screenshots necessary to recreate these solutions yourself.

Who this book is for

Targeted at individuals already familiar with BizTalk Server and not those expecting a full tutorial on every aspect of the product, this book is ideal for architects and developers who want to develop the most maintainable BizTalk Server solutions possible. This is the first book available on BizTalk Server 2009 and covers all relevant features for those of you designing a BizTalk business solution.
