Web Services Custom Data Binding, Part 1: How to choose a custom mapping technology for Web services
In most scenarios, the mapping from XML schema to Java, as defined by JAX-RPC, yields a suitable set of Java beans for handling your Web services data. However, there are cases when you may prefer an alternate mapping, or when there just isn't a well-defined mapping for your particular schema construct (xsd:choice is a common example). For these cases, IBM WebSphere V6 has introduced a new feature called Custom Data Binding that allows you to integrate alternate data binding technologies like JAX-B, EMF/SDO and XML beans, as well to define your own XML schema to Java mappings. This article provides an overview of the technology and how you can get started integrating it into your application.
