 How is the binding's port null in the provider if the processor previously

 provided a port by calling binding.getPortName().  Since the binding model
 is still marked unresolved, it returns null (this is wsdl.service so there
 is no port name).  This causes WSDLServiceGenerator to import all the
 bindings and set the binding's port to null.

 Why is the binding model still unresolved?  Well, the processor's resolve
 operation never marks it resolved.

 So, if the provider already has to select the port, why not have it use the
 SOAP intent to drive a selection?  Well, when the binding processor selected
 the first port, it set the binding uri to that port's address.  Then when
 WSDLServiceGenerator copies the ports over to the wrapper WSDL, it stores
 the binding uri into the port address.  So the address to use is clobbered.

 Ok, let's change the binding processor to not select a port for wsdl.service
 since the provider's going to choose it anyway.  Well, when I tried this, I
 got a NoSuchElementException in WebServiceBindingImpl.setIsDocumentStyle().
  The binding is null, so it looks for the first WSDL Message in the
 Definition to determine the document style.  In my case the main WSDL
 document has no Messages of its own but imports them from another file.  I
 suppose this is a problem that could be hit in other ways and I just got
 unlucky.

 I guess I can continue to poke away at this, but I'm beginning to wonder if
 this functionality is worth the effort.

 Sounds right to me.

It sounds like that to get the WSDL gen to work properly the port has
to be selected before the provider runs. But it looks like this test
can't even be moved to the WebServiceBindingBuilder as that runs
before the CompositePolicyBuilder. Tricky.

The fix that first comes to mind based on what you've described is to
try and correct the WSDL gen piece so that it doesn't mess up the URL
so that there is a chance of performing the proper selection in the
provider.

Re: Question about wsdl.service and SOAP intent

2012-02-17 Thread Greg Dritschler
I was thinking about having the WebServiceBindingBuilder perform the port
selection. It calls the WebServiceBinding methods getBinding(),
setBinding(), and setGeneratedWSDLDocument() which
drive determineWSDLCharacteristics() under the covers.  It seems like this
should be done consistently with the final port selection.

Off the top of my head, I can't see why CompositePolicyBuilder would depend
on WSDLServiceGenerator running first.  Maybe I should try reversing them.
