Integrating multiple systems in a point to point manner can be very time consuming and expensive to maintain. One common approach to resolve this issue is to introduce an Enterprise Service Bus (ESB), which replaces the point to point approach with a single, centralized place to integrate systems, and does so in a service-oriented manner. However, if done incorrectly, this can still create maintenance headaches. Here is a look at a pattern that can “future proof” your integration work, allowing for the upgrading or replacement of legacy systems without excessive additional...

This article describes how you can make your web services enterprise-ready using the WS-Atomic Transaction (WS-AT) protocols in conjunction with IBM WebSphere Application Server's unparalleled transaction, high availability, and failover support. Beginning with a close look at the protocol itself and the WebSphere Application Server specifics (when running a web services client or the web services provider), the article will depict the optimizations that are being used when both client and service provider use WebSphere Application Server as the runtime platform, and show you how to...

The Modern Batch feature for IBM WebSphere Application Server provides a robust Java batch programming model that enables the integration of online and batch processing within an architected framework across multiple platforms. This series describes the programming models that the Modern Batch feature provides and demonstrates the new functionality provided in IBM Rational Application Developer V8.0 that greatly simplifies the development of batch applications and the associated xJCL required for job submission. Part 1 introduced Modern Batch and showed a sample implementation for the...
