testing a sample SOAP based service .. but getting error "premature end of file"

I know that usually REST is preferred to SOAP (which is complex).

http://www.somebits.com/weblog/tech/bad/whySoapSucks.html?seemore=y

And I've read here that SOAP based reads cannot be cached.

http://spf13.com/post/soap-vs-rest

...

But noting these warnings .. just as a learning exercise I'm trying out calls to a typical SOAP web service.

http://www.pastie.org/457535

I've placed this xform definition as view.xhtml in /resources/apps/weather-service/
and created a simple page-flow.xml

<config xmlns="http://www.orbeon.com/oxf/controller">
    <page path-info="/weather-service/" view="view.xhtml" />
    <epilogue url="oxf:/config/epilogue.xpl"/>
</config>

but when I try launching ..

http://localhost:8080/orbeon/weather-service/

I get error message .. "premature end of file"

Any advice on what could be the cause of this error?

Usually this is an XML parser error. Anything in the logs?

Here is a dump of orbeon.log which points to ..

2012-07-07 19:21:39,677 ERROR ProcessorService  - Exception at line 1, column 1 of file:///
org.xml.sax.SAXParseException; systemId: file:///; lineNumber: 1; columnNumber: 1; Premature end of file.

but no file identified .. only file:/// ????

I've also found that the weather service URI has changed over the years .. the new API and namespace are below ..

Here is my progress on using National Weather Service as a test SOAP service

I installed soapUI from http://www.soapui.org.
I created a project using the wsdl.
I invoked the NDFDgenByDay request operation in soapUI to see the soap envelope expected.
I inserted a few test parameters
and tried launching

http://localhost:8080/orbeon/weather-service/

but although the xform renders in browser I still get parsing errors.  
org.xml.sax.SAXParseException;
Here is the xform definition.
Can you see any glaring errors?
