Mock Web services with Apache Synapse to develop and test Web services

Apache Synapse is a simple, lightweight, high-performance enterprise service bus (ESB) released under the Apache License, Version 2.0. But for an individual developer, what’s the use of an ESB product in your day-to-day life? The simplicity of the configuration, out-of-the-box feature set, extensible architecture, and the minimal footprint makes it a versatile and powerful tool that you can use for a variety of tasks.

In this IBM developerWorks tutorial, I will explain how you can use Apache Synapse to create mock Web services. The target Web service clients and services can be in any language, such as Microsoft® .NET, Java, or PHP.
