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, RMI-IIOP 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 effort

Using J2EE as the base platform for EAI

Integration of data using XML, JDBC and JMS

Integration of applications using CORBA, RMI-IIOP, EJB, and JCA

Integration of user interfaces using XML, servlets and JSP

Integration of transaction and security systems

B2B integration with web services
