Enterprise Application Integration (EAI) has been the driving force behind application and information system development of the last few years. The Java 2 Platform, Enterprise Edition (J2EE) provides an ideal environment in which to integrate different domains, architectures, and technologies to create available, scalable, and secure enterprise information systems. This book presents a methodology and process to create an integrated information infrastructure based on the J2EE platform, using technologies such as XML, EJB, JMS, CORBA, RMIIIOP and the J2EE Connector Architecture. This infrastructure provides an architecture that facilitates integration at the data, component, and application levels. Through the use of component wrappers and virtual components, existing applications can be replaced and new developments seamlessly integrated into the integrated architecture. The book takes you through the various stages in the integration process, from design and analysis, through integration of data, via integration of components and applications, to the integration of the user interface. At each stage the book discusses the relevant Java technologies that enable a common integration platform and how to employ them to this purpose. This book covers:An integration process for evaluating existing systems and coordinating the EAI effortUsing J2EE as the base platform for EAIIntegration of data using XML, JDBC and JMSIntegration of applications using CORBA, RMIIIOP, EJB, and JCAIntegration of user interfaces using XML, servlets and JSPIntegration of transaction and security systemsB2B integration with web servicesThis book is for J2EE developers who need to learn how to create an integrated information system. The book presents an integration architecture and process from first principles, but familiarity with the J2EE technologies is preferable. About the AuthorMatjaz B Juric holds a Ph.D. in computer and information science and is an Assistant Professor at the University of Maribor. His research areas cover all aspects of component technology, with special emphasis on integration, distributed object and component systems (CORBA, EJB, RMI, COM+, .NET), component development, Web Services, performance, analysis, and design. He has gained experience from several largescale integration projects, and he has been involved in the RMIIIOP (an integral part of the Java 2 platform) development for performance analysis and optimization. Matjaz is author of several scientific and professional articles in journals like Java Report, Information and Software Technology, ACM journals, etc. He coauthored the book Professional EJB (Wrox Press) and published a chapter in the book More Java Gems. He has presented at conferences like OOPSLA, ICPADS, PDCS, Java Development, and SCI. He is also a reviewer, program committee member, and conference coorganizer. S. Jeelani Basha is working as a Senior Software Engineer with Infinity Markets, Inc., California. His interest in programming led him from electrical engineering to software programming. He is a certified Java2 Programmer with more than 5 years of experience and has implemented various projects using J2EE. His current subject of interest is Web Services and he concentrating his efforts towards making Web Services a viable solution for enterprise applications. He has a bachelors degree in Electrical Engineering from REC Bhopal, India. Rick Leander has worked in software development for over twentyfive years and is currently owner of Zeno Street Software, a Denver based consulting firm. He has gained a wealth of EAI experience while integrating vertical market software for managed healthcare organizations throughout the Unites States and has refined this knowledge with graduate research while completing his M.A. from Webster University. In addition to EAI, his technical interests include EDI, XML, databases, and distributed business application development. He lives in the Denver, Colorado area with his wife Barb and his dog Freckles. Ramesh Nagappan is an Architect specializing in Java and CORBAbased distributed computing architectures. He is a Java evangelist and also an active contributor to open source specifications and implementation. Before he hooked on to Java and CORBA, he worked as a Research Engineer for developing software solutions for CAD/CAM, Computational fluid dynamics solutions, and Aerodynamics applications. In his spare time, he enjoys water sports and playing with his son Roger. He can be reached at nramesh@mediaone.net.
