After lots of issues, I can now successfully expose a BPEL component
using the Tuscany WS Binding.
Let me try to summarize the issues I found, and how I fixed and/or
workarounded them:

- TUSCANY-2316 - The ws-binding was overriding the databinding
definition on the contract and causing issues. I have cloned the
interface contract in the axis binding code
(Axis2ServiceBindingProvider)

- TUSCANY-2321 - When invoking the BPEL component from a regular pojo,
the databinding framework was passing a DOM Element during invocation,
but when the BPEL component was exposed using ws-binding it was
receiving a DOM Document. I have workarounded this issue in impl-bpel
by supporting the two DOM Object types for now.

- The last issue was related to how the ws-binding calculates the wsdl
service QName. When exposing the BPEL component as webservice, the
ws-binding (Axis2ServiceClient.setServiceAndPort) the service QName
was being calculated to " {ns}HelloPortType_Service" instead of "
{ns}HelloService" as defined in the wsdl, I have workarounded this by
explicitly defining the service as part of the binding.ws in the the
composite file like :<binding.ws
uri="http://localhost:8085/HelloPartnerLink";
wsdlElement="http://tuscany.apache.org/implementation/bpel/example/helloworld.wsdl#wsdl.service(HelloService)"/>.
It would be good if someone could jump and give a quick help here.

I have committed all the fixes/workaround mentioned above, and also
added a itest/bpel/helloworld-ws project that exposes a BPEL component
using webservices (ws-binding).

Please let me know if you have questions/comments.
