Since WSIT builds upon JAXB, you can use the existing JAXB 2.0 programming model (for most part) when developing JAX-WS web services and clients. Thus, for example, you can:

• Develop a Java web service starting from Java classes ( Java web service starting from Java ). And the classes used in designing the JAX-WS web service can be annotated using JAXB annotations . JAXB annotations customize the generated schema in the service WSDL generated from JAX-WS based web service. This service WSDL can then be used to create WCF clients.
• Generate Java client side artifacts from a WCF service WSDL. The generated classes contain the appropriate JAXB annotations.

We are working on adding more information related to databinding interoperablity in the next version of WSIT tutorial .

To try out JAXB in WSIT, download the WSIT binary ( WSIT Milestone 2 Released ) . The JAXB version in the WSIT binary includes fixes to issues/bugs uncovered by the databinding interoperability testing between WCF XML serialization mechanisms and JAXB.
