WSIFServiceFactory not setting port when creating service

[D]

Hi All, I'm having a problem retrieving a port from a service I've just
created, namely because there is no port entries in the property myPortsMap
in WSIFService. Below is the code for creating the service:

WSIFServiceFactory factory = WSIFServiceFactory.newInstance();

 WSIFService service =
factory.getService("file:///D:/sandbox/BAIT/docs/BaitEJBWsdlExample.wsdl",
null,
       null, "http://bait.testEJB/";,
       "DemoSession");

 // get the port
 WSIFPort port = service.getPort();

Here's also the WSDL file called, it's very basic, with only one method
demoSelect listed, it has no input parameters, it just returns a string.
I've modelled it on the EJB wsdl example given on the website, when I
debugged the  example ejb.client.dynamic.Run class up until WSIFPort port =
service.getPort(); , there is no problem and a port is present in the
myPortsMap Hashmap with the key EJBPort as in the WSDL file, so I'm assuming
that I have made a mistake somewhere in the WSDL file, but I can't see what
it is.

                       jndiProviderURL="localhost:1099"/>
    </port>
  </service>

</definitions>

If anyone has any ideas or tips as to why this is not creating a port I
would appreciate hearing them.

Thanks
