Paul Robinson commented on JBTM-986:
------------------------------------

The general approach I would take to implementing this feature would be:

* Read about JAX-WS features in the Spec
* Look at how MTOM et al are currently implemented in CXF.
* Create a "Hello World" feature that just prints something to the console.
* Update the feature to add the XTS client-side handler to the client-side handler chain.
* Figure out how to have the feature enabled by default, so that the XTS client-side handler is added even if the developer doesn't specify the feature.
* Add some configuration to the XTS section of the standalone-xts.xml to have transaction context propagated by default.

> When invoking a WS-AT or WS-BA Web service, the client side handler has to be added to the client stub to manage transaction context propagation. The code required to do this is as follows:
> {code}
> BindingProvider bindingProvider = (BindingProvider) client;
> List<Handler> handlers = new ArrayList<Handler>(1);
> handlers.add(new JaxWSHeaderContextProcessor());
> bindingProvider.getBinding().setHandlerChain(handlers);
> {code}
> This is not very user friendly.
> This could be done using a JAX-WS feature passed to the Client-side port.
> We also need to support client stubs created using @WebServiceRef. Here's some examples of its use:
> http://anonsvn.jboss.org/repos/jbossws/shared-testsuite/trunk/testsuite/src/test/java/org/jboss/test/ws/jaxws/samples/webserviceref/
> http://anonsvn.jboss.org/repos/jbossws/shared-testsuite/trunk/testsuite/src/test/resources/jaxws/samples/webserviceref/
> http://anonsvn.jboss.org/repos/jbossws/shared-testsuite/trunk/testsuite/src/test/ant-import/build-samples-jaxws.xml
> The feature should be "enabled" by default providing the feature is enabled in the XTS server config.
> The quickstarts also need updated to use this.
