"It’s a fact the .NET and Java platforms exist in the enterprise with many touch points. Developers are very eager for information and examples on how the two environments can coexist. This book reflects our interoperability collaboration with Sun and provides best practices for using Web services to bridge .NET and Java applications." --DAN’L LEWIN corporate vice-president, Developer & Platform Evangelism, Microsoft Corp. "This book is a developer handbook for implementing interoperable applications and services. It includes actionable strategies for developers and best practices from the field experience." --GREG PAPADOPOULOS chief technology officer, Sun Microsystems "A comprehensive, practical guide to developing applications that cross the Java EE .NET boundary." --BILL SMITH director business alliances, Sun Microsystems "Efficient, effective interoperability between Java EE and .NET is a crucial element in the IT architecture of large enterprises and is vital to running a successful business.This book takes interoperability to the next level, far beyond the cold coexistence of systems, by describing effective strategies that allow you to achieve true interoperability while reducing complexity in your applications and your data center. Additionally, it provides examples and practical advice on how to achieve this new level of interoperability and covers in depth all of the options available from bridging, to porting, to platform unification. The costs that this can save you, from management, maintenance and server consolidation are very significant." --YAACOV COHEN chief executive officer, Mainsoft "A complete and up-to-date coverage of Java EE .NET security interoperability standards and related specifications." --HUBERT A. LE VAN GONG architect, Sun Microsystems, and the coauthor of "Web SSO MEX Specification" Evolving Web services standards and technologies offer limited interoperability when it comes to security, management, and other important application characteristics. Successful interoperability solutions require comprehensive integration strategies that go beyond simple connections.The capability to mitigate security and reliability risks and transactional support is critical to interoperability. Java EE and .N ET Interoperability addresses issues encountered during the integration process, such as a diverse technology set, incompatible APIs, and disparate environment maintenance. The experienced authors outline strategies, approaches, and best practices, including messaging, Web services, and integration-related frameworks and patterns. The book also introduces readers to Service Oriented Architecture (SOA), the building block for scalable and reliable enterprise integration solutions. This indispensable book provides the Java EE and .NET developer community with multiple strategies to integrate between Java EE and .NET platforms that save developers time and effort. Applying proven interoperability solutions significantly reduces the application development cycle. Coverage includes * Effective Java EE--.NET integration strategies and best practices * Detailed enterprise coverage, as well as standalone Java EE component integration with .NET * SOA as a building block for Java EE--.NET interoperability * Interoperability security issues and risk mitigation * Managing reliability, availability, and scalability for Web services built on Java EE and .N ET * The latest interoperability standards and specifications, including Web SSO MEX and WS-Management * Current interoperability technologies, such as Windows Communication Foundation, WSE 3.0, JAX-WS, and Enterprise Service Bus

In 2004 Microsoft and Sun announced that they would bury the hatchet and begin working together on interoperability between their servers and products. In May 2005, they showed the world the first specifications of how they will make this interoperability a reality. In the meantime, each platform has their strengths---J2EE for large projects, security---.NET for smaller projects, shorter life cycles---and the majority of large corporations are using both J2EE and .NET. This book features fourteen valuable strategies and patterns for J2EE-.NET integration and shows how to implement these strategies in real life scenarios. Individual strategies are explained with respect to the specific problem domain, solution, benefits, and limitations. It discusses important aspects of J2EE-.NET application interoperability such as access to a shared data model, while maintaining data integrity. Each strategy encompasses a complete solution to the described problem, thus allowing a developer to pick and read selected chapters of the book. Strategies are accompanied with UML diagrams and sample code that helps to expedite the application development. Enterprise developers looking for an industry proven mechanisms to overcome J2EE-.NET integration challenges will find this book indispensable.

Not deep enough and poor examples.
This book covers many topics, unfortunately it does not go into great detail and less than a hello world example. I am confused and don’t know what the authors really mean about interoperbility with this book. The content is a bit vague and poorly written. The examples are hardly usable and the best practices sections does’nt make sense. Some of the topics covered have nothing to do with interoperability, they are integration topics. If you are really looking integration guidance, choose Enterprise Integration Patterns by Gregor Houpe et all.

Not detailed enough and poor examples
The first couple of chapters are OK. Thereafter I found the integration concepts and strategies half done and hardly complete. The code examples are not commented at all. I noticed the code would work only on sun application server and the configuration details are not discussed are missing. I tried to deploy the code example using websphere 6 it did’nt run at all. The chapters in part3 and part4 are more of theoretical coverage and kind of standards work in progress. In comparison, I like Application Interoperability - Patterns and Best Practices from Microsoft Press over this book. This book did’nt help me at all.

Good information for the right audience...
As much as Microsoft might want you to be an all-.NET shop, the reality of the enterprise computing environment is that both .NET and Java will be used in some way, shape, or form. If you’re a developer or architect responsible for integrating platforms, this book could help you out... Java EE and .NET Interoperability : Integration Strategies, Patterns, and Best Practices by Marina Fisher, Ray Lai, Sonu Sharma, and Laurence Moroney.

Index

The book is targeted towards developers as well as architects and managers responsible for these types of projects. The focus and approach tends more towards the practical, "here’s one way to do it" methodology. There’s no hesitation to suggest third-party frameworks and applications to help you accomplish something, as well as providing enough code to allow the reader to get a feel for how it all fits together. It’s not a comprehensive approach to every last thing you need to know, but if you’re charged with platform integration, this will give you the practical foundation you’ll need to start examining the options available to you.

Given the right needs and the right audience, it’ll offer value to the reader...

Little bit of everything !
The first 3 chapters discusses on real standards interoperability after that its all about traditional integration. After reading this book - now I am really confused about the meaning of integration and interoperability. For example, the book suggests to use cots products like jintegra, jnbridge and opensource iiop.net for java - .net interoperibility. For platform unification strategy (page 529), the book suggest mainsoft binary compiler. The book also discusses on messaging middleware for asynchronous integration and calls them as messaging interoperability. The first 3 chapter uses SOAP based rpc mechanisms and ws-i techniques beyond that this book is all about integration. The book conflicts strategies with patterns, for example GoF claim adapter is a pattern this book calls it as a strategy. The books also more biased to sun and I find the content is more confusing, repetitive and with less explanation.
