Simon Nash updated TUSCANY-1341:
--------------------------------
Attachment: jira1341-take2-patch3
This patch updates the samples pom.xml and README to include the
simple-callback-ws sample in the build. This sample shows how to use callbacks
across the Web Service binding. Before applying this patch,
jira1341-take2-patch2 must be applied.

> The callback function using WS bindings doesnt appear to be operation. So
> far I have :
> 1) WebServiceBindingProcessor.java
> - The resolve() method does not setup the callbackInterface on its
> InterfaceContract resulting in NPE.
> (i.e. interfaceContract.setCallbackInterface(wsdlCallbackInterface); )
