Java Business Integration

Abstract: The paper presents a Monitoring Framework for the integration layer of SOA systems realized by an Enterprise Service Bus (ESB). It introduces a generic ESB Metamodel (EMM) and defines mechanisms which gather monitoring data related to the model entities. Applicability of the model is verified on the Java Business Integration (JBI) specification-available standardization of an ESB. An analysis of the JBI specification from the Metamodel perspective is presented, resulting in identification of JBI monitoring deficiencies. Then, the paper illustrates a realization of mechanisms ameliorating JBI deficiencies. The paper also defines the notion of a Monitoring Goal Metamodel which lays a foundation for a fully featured and technology-agnostic monitoring framework established on the EMM. The Monitoring Goal Metamodel allows a declarative definition of how the framework should react to anomalies by performing drill-down monitoring to diagnose the root cause of the problems. Evaluation of the prototype implementation of the ESB Monitoring Framework that verifies its correctness and fulfillment of the nonfunctional requirements is presented. Related work and some important relevant projects and technologies are also briefly described. Finally, the paper is summarized with conclusions and a vision of the proposed framework usage and extensions.

Abstract: In Detail The goal of Java Business Integration (JBI) is to allow components and services to be integrated in a vendor-independent way, allowing users and vendors to plug and play. Java Business Integration (JBI) is a specification aiming to define a Service Provider Interface for integration containers so that integration components written for these containers are portable across containers and also integrate with other components or services using standard protocols and formats. JBI is based on JSR 208, which is an extension of Java 2 Enterprise Edition (J2EE). This book first discusses the various integration approaches available and introduces the Enterprise Service Bus (ESB), a new architectural pattern that facilitates integrating services. ESB provides mediation services including routing and transformation. Java Business Integration (JBI) provides a collaboration framework that provides standard interfaces for integration components and protocols to plug into, thus allowing the assembly of Service-Oriented Integration (SOI) frameworks following the ESB pattern. Once JBI and ESB are introduced, we look at how we have been doing service integration without either of these using traditional J2EE. The book then slowly introduces ESB and, with the help of code, showcases how easily things can be done using JBI. What you will learn from this book? Assembling services and porting them across containers using JBIExposing EJB as a WSDL-compliant service across firewallsBinding remote services to ESB to be consumed internallyExposing local components in ESB like POJO as externally accessible WSDL-compliant services Providing a web service gateway for external consumersAccessing web services over a reliable transport channel like JMSImplementing web service versioning using ESBImplementing service aggregation at ESBTransactions, Security, Clustering, and JMX in ESB Approach The book covers all concepts with examples that can be built, deployed, and run by readers using the Apache Ant tool in Apache ServiceMix, which is an open-source Enterprise Service Bus that combines the functionality of a Service Oriented Architecture (SOA) and an Event Driven Architecture (EDA). The aim of this book is to prepare an architect or developer for building integration solutions using ESB. To that end, this book takes a practical approach, emphasizing how to get things done in ServiceMix with code. When needed, it delves into the theoretical aspects of ESB, and such discussions are supplemented with working samples. The book, thus, distils some of the knowledge that has emerged over the last decade in the realm of Java Integration. Who this book is written for? This book is aimed at Java developers and integration architects who want to become proficient with the Java Business Integration (JBI) standard. Readers should have some experience with Java and have developed and deployed applications in the past, but need no previous knowledge of JBI. The book can also be useful to anyone who is struggling to understand ESB and how it differs from other architectures and to understand its position in SOA. This book primarily targets IT professionals in the field of SOA and Integration solutions--in other words, intermediate to advanced users. You are likely to find the book useful if you fall into any of the following categories: A programmer, designer, or architect in Java who wants to learn and code in JBI or ESB. A programmer, designer, or architect who doesn't normally code in Java can still benefit from this book, since we 'assemble integration components' using XML with little to no Java code. An IT Manager or an Officer who knows well about SOA or SOI but want to see something in code (you can adorn your flashy presentations with some live code too).

Abstract: In Detail Composite applications aid businesses by stitching together various componentized business capabilities. In the current enterprise scenario, empowering business users to react quickly to the rapidly changing business environment is the topmost priority. With the advent of composite applications the `reuse' paradigm has moved from the technical aspect to the business aspect. You no longer re-use a service. You re-use a business process. Now enterprises can define their own behaviors optimized for their businesses through metadata and flows. This business process composition has become increasingly important for constructing business logic. The ability of composite applications to share components between them nullifies the distinction between actual applications. Business users should be able to move between the activities they need to do without any actual awareness that they are moving from one domain to another. The composite application design enables your company to combine multiple heterogeneous technologies into a single application, bringing key application capabilities within reach of your business user. Enterprises creating richer composite applications by leveraging existing interoperable components increase the organization's ability to respond quickly and cost-effectively to emerging business requirements. While there are many vendors offering various graphical tools to create composite applications, this book focuses on using the BPEL service engine from the OpenESB project for solving business integration problems. Project OpenESB implements an Enterprise Service Bus runtime using Java Business Integration (JBI) as the base. This allows easy integration of web services to create loosely coupled enterprise-class composite applications. The objective of this book is to help enterprise application architects and developers to understand various SOA tools available as part of the NetBeans IDE that will enable them to build an enterprise-grade, scalable application in a short period using a single development interface. The NetBeans SOA tools form an open-source and freely available add-on to the NetBeans IDE that is targeted for enterprise application development. This pack contains open-sourced features from Sun's Java Studio Enterprise and Java CAPS products, as well as all-new features for creating composite applications, BPEL-based web services, secure Java EE web services, and real-world XML artifacts like XML Schema and WSDL. Part of NetBeans Enterprise Pack is integrated with NetBeans 6.0, so you don't need to download additional add-ons or plug-ins if you are using NetBeans version 6.0 or higher. However, not all OpenESB components are integrated with NetBeans 6.0. For instance you may not be able to create an Intelligent Event Processor using the standard NetBeans IDE; these components can be downloaded and installed into the NetBeans IDE. What you will learn from this book? Basic understanding of SOA and BPEL ProcessesSetting up NetBeans IDE, OpenESB runtime, and BPEL engineDesigning BPEL processes Packaging and deploying BPEL processes JBI runtime and GlassFish Application Server.Using the JBI service engine in NetBeansOpenESB Binding Components, Service Engines, and other tools Using the WSDL Editor for enterprise applicationsRapid development and testing with the XML schema designerWorking with the Intelligent Event Processor (IEP) module and the IEP Service EngineFault handling within a BPEL process Approach This book introduces basic SOA concepts and shows how you can use NetBeans and OpenESB tools to design and deploy composite applications. After introducing the SOA concepts, you are introduced to various NetBeans Editors and aids that you need to understand and work with for designing a composite application. For example you are introduced to a WSDL editor before dealing with web services. The last part of the book deals with a full-fledged incremental example on how you can build a complex composite application with key screenshots accompanied by the source code available on the website. Who this book is written for? This book is for enterprise developers and architects interested in using NetBeans IDE and OpenESB tools to build their SOA based applications.
