Hi,

When I use address location in my wsdl without http:// and with a port  
like  
:

my.location:7800

in

\<wsdl:service name=“WebServices”\>  
\<wsdl:port name=“WebServicesPort” binding=“aws:WebServicesBinding”\>  
\<soap:address location=“my.location:7800”/\>  
\</wsdl:port\>  
\</wsdl:service\>

I have an error from C:\ruby\lib\ruby\site\_ruby\1.8\http-access2\http.rb

from the function

def create\_query\_uri(uri, query)  
path = uri.path.dup  
path = ‘/’ if path.empty?  
query\_str = nil

The error is : Exception `TypeError’ at  
C:/ruby/lib/ruby/site\_ruby/1.8/http-access2/http.rb:270 - can’t dup  
NilClass

because uri.path returns nil.

So is there a way to use that kind of location or is it a Ruby lack?  
Thanks.

soap:address requires an URI so you must supply ‘http://’, ‘https://’,  
etc. here. Is there any reason why you can’t do that?

Anyway, http-access2 should raise more friendly error message.

I’ve just check the W3C documentation for the wsdl syntax (  
[Web Services Description Language (WSDL) Version 2.0 Part 1: Core Language](http://www.w3.org/TR/wsdl)) and I think it is my mistake. The URI must  
have a  
scheme: http:// https:// ftp:// mailto:// …

So we have to modify our soap address location so that we can access  
them  
through http protocol.

Cheers,
