Java CAPS Basics Implementing Common EAI Patterns

Use Java CAPS to Streamline IT Services and Leverage Legacy Applications Design patterns are a useful tool for streamlining enterprise integration and Web development projects: the mission-critical projects that directly impact your competitiveness.Enterprise Integration Patternsby Gregor Hohpe and Bobby Woolf (Addison-Wesley, 2004) described many of the most useful patterns for enterprise developers. Until recently, however, implementing the patterns in that classic reference required the extensive use of raw Java code. Now therers"s a better alternative: Using Sunrs"s Java Composite Application Suite (Java CAPS), architects and developers can implement enterprise integration patterns succinctly, elegantly, and completely. InJavatrade; CAPS Basics, Sunrs"s own Java CAPS experts show how to quickly put these new tools and technologies to work in your real-world enterprise application integration projects. After reviewing the challenges of enterprise integration, they introduce Java CAPS and show how it can simplify the development of todayrs"s state-of-the-art "composite" applications. Next, they bridge the gap between abstract pattern languages and practical implementation details. You will learn essential Java CAPS concepts and methods in the context of the patterns yours"ll actually use for real-world message and system management. Coverage includes Comparing approaches to enterprise application integration and finding ways to integrate non-invasively, with fewer changes and lower costs Mastering the core integration tools provided by Java CAPS: eGate, eInsight, eWays and JMS Using enterprise integration patterns to improve application reusability, scalability, resilience, security, and manageability Implementing patterns for message exchange, correlation, infrastructure, routing, construction, transformation, and endpoints Generating and using cryptographic objects such as X.509 Certificates, PKCS#12, and JKS Keystores Using advanced techniques such as solution partitioning and subprocess implementation, many of which are covered nowhere else Constructing two complete example solutions that bring together many of the patterns discussed and illustrated in this book The companion CD contains detailed illustrations for most of the relevant patterns and two complete Java CAPS-based case studies (with solutions) that implement a number of the patterns discussed in the book. In addition, Part II contains a chapter on cryptographic objects used to configure security-related aspects of the suite. It also provides more than sixty detailed examples designed to illustrate the concepts and patterns presented in this book. Built with JCAPS eDesigner, these graphical, component-based examples can easily be used by business analysts and others with or without strong coding skills.

Michael has written a number of technical whitepapers on various topics for ICAN and Java CAPS, addressing, among others, Java CAPS security configuration, WS-Security implementation in Java CAPS, and application of EAI patterns to Java CAPS solutions. He is a Java CAPS Apostle, an active contributor to Java CAPS communities and forums, and a presenter at various industry conferences.

Sebastian Krueger started working on EAI software with SeeBeyond ICAN 5.0.5 in late 2005 and has since worked on all Sun Java CAPS eGate, eInsight, and eXchange product components, as well as on JMS Grid.

Initially providing Java CAPS consulting services to the New Zealand market, he now works for the Inland Revenue Department of New Zealand, where he is a senior analyst programmer.

Sebastian is a Sun-Certified Java Programmer and an LPI-Certified Linux Professional.

Brendan Marry has over 10 years of experience in IT and is currently an integration solutions architect for Sun Microsystems in Auckland, New Zealand, responsible for the design and delivery of enterprise integration architectures using Java CAPS.
He has over 4 years of experience at Sun, specifically around the Sun Java CAPS. Brendan worked in the Java Mobile space and Java Enterprise space in Europe before immigrating to New Zealand and joining Sun.

Peter Vaneris has 19 years of experience in the IT industry, the last 2 in the field of Java CAPS support. Prior to working with Java CAPS, Peter specialized in system administration, monitoring, automation, and enterprise management.

Andrew Walker has 18 years of experience in IT and originally joined SeeBeyond in January 1999, where he started working with one of the early EAI software products, then known as DataGate. Subsequently, he has worked with all the EAI software products released by SeeBeyond and now Sun Microsystems. Andrew has broad experience in architecting and implementing EAI and SOA solutions for customers in the Asia–Pacific region. He is currently based in Singapore and provides Java CAPS consulting services throughout the Asia–Pacific region as part of his job role in Sun Microsystems Professional Services.

In their bookEnterprise Integration Patterns: Designing, Building, and Deploying Messaging SolutionsEIP, Gregor Hohpe and Bobby Woolf elaborate on the subject of Enterprise Application Integration using messaging. They present, discuss, and illustrate over sixty EAI design patterns. These patterns, they believe, are key patterns most designers of EAI solutions will use when building enterprise integration solutions. Most examples in EIP use raw C# and raw Java to illustrate details of EAI patterns under discussion. Most of these patterns can be implemented succinctly, elegantly, and comprehensively using tools and technologies provided in the Sun Java Composite Application Platform Suite Java CAPS. This book is about implementing selected enterprise integration patterns, discussed in EIP, using Java CAPS as the means to building practical enterprise integration solutions. It bridges the gap between the somewhat abstract pattern language and the practical implementation details. It is designed for integration architects, solution architects, and developers who wish to quickly implement enterprise solutions with Java CAPS. It discusses how enterprise integration patterns can be implemented quickly and efficiently by leveraging the Java CAPS tools and the authors' field experience. While this book discusses Java CAPS implementation of EIP patterns, it does not discuss the patterns in depth. It is assumed that you are already familiar with the subject and need to apply the theoretical knowledge using Java CAPS. This book is also about basics of the essential Java CAPS Suite components, based on the premise that you cannot apply patterns if you cannot effectively use the tools with which to do it. Since the complete Java CAPS offering has so many components, including ones that are not essential to integration, this book elaborates only on the basic integration tools: eGate, eInsight, eWays, and Java Message Service (JMS). This book also provides information you may need to effectively use Java CAPS. A considerable amount of Java CAPS-related material, provided in the text, is not published anywhere else. The accompanying CD-ROM provides over 60 detailed examples that illustrate concepts and patterns under discussion. Some examples are high level, illustrating specific points. Other examples follow a step-by-step approach. Java CAPS projects discussed and developed as examples are available for import and perusal. How This Book is Organized This book is divided into three sections. Section I, "Preliminaries," contains chapters that discuss integration and background Java CAPS topics, including enterprise integration styles, Java CAPS architecture, and project structure and deployment. Section II, "Patterns Review and Application," covers most EIP patterns with discussion of Java CAPS approaches to implementing them. This section includes chapters dealing with message exchange patterns, message correlation, messaging infrastructure, message routing, message construction, message transformation, messaging endpoints, and system management patterns and concepts. While discussing Java CAPS implementation of specific patterns, relevant Java CAPS concepts and methods are also discussed. When discussing implementations of the Message Sequence pattern, for example, Java CAPS concepts of JMS serial mode concurrency, Sun SeeBeyond JMS Message Server FIFO modes, and serializing eInsight Business Processes via JMS and XA are also discussed. Section III, "Specialized Java CAPS Topics," discusses non-pattern matters of importance like solution partitioning, subprocess and Web Services implementation, management, reusability, scalability and resilience options, and others that are not covered elsewhere. This section also covers security features of Java CAPS. The accompanying CD-ROM contains over 60 detailed examples implementing most of the patterns and concepts under discussion as
