Create a Web Module on Windows XP
Add a simple WS in it with a simple operation
Deploy it

Create an App Client
Use the wizard to point to the preview WS for WS Client.
Enter whatever package name (foo)

Code the main to inect the web service reference as:

    /** Creates a new instance of Main */
    public Main() {
    }
    @WebServiceRef(foo.FirstWSService.class) private static foo.FirstWS ws;

    
    /**
     * @param args the command line arguments
     */
    public static void main(String[] args) {
        // TODO code application logic here
        System.out.println(""+ws.sayHello("sdfsdf"));



Run this Application Client. 
You'll see a runtime error:

java.net.URISyntaxException: Illegal character in opaque part at index 2:
C:\abill\projects\ApplicationClient6/src/conf/xml-resources/web-service-references/FirstWSService/wsdl/localhost_8080/demo1/FirstWSService.wsdl

    }



Char 2 of C:\abill\projects\App
is the ":" Windows separator.

What is means is that the WSIMPORT command in build-impl.xml is not correct.

It is missing the 
 wsdllocation="http://localhost:8080/demo1/FirstWSService?WSDL" 

parameter.

Otherwise, the app client jar needs to have a reference to an absolute path on
your PC (bug), and also that the code to load this absolute path is broken for
PC url ...


This is a demo blocker...
