[Mono-list] Accessing an XSP hosted c# webservice via Javascript in mozilla?

[none none]

Ok so I've installed XSP and I'm running the test setuo that it comes
with which exposes the test service that has two methods you can use
("Echo" and "Add"). I've written a small c# app that access it and
that works fine, but I'm trying to access it using javascript in a
mozilla gecko based browser using the following code:


var proxy    = null;
var wsdl_uri = "http://localhost:8080/1.1/webservice/TestService.asmx?wsdl=0";

function setup_webservice()
{
	try {
		var listener = {
			onLoad: function (aProxy)
			{
				proxy = aProxy;
				proxy.setListener(listener);
				
				/* the following call fails */
				proxy.Add(4, 8);
			},

			onError: function (aError)
			{
				alert("An error occured!!!!!\n")
				alert(aError);
			},

			EchoCallback : function (result)
			{
				alert(result);
			},

			AddCallback : function (result)
			{
				alert(result);
			}
		};

		var factory = new WebServiceProxyFactory();
		factory.createProxyAsync(wsdl_uri, "TestServiceSoap", "", true, listener);
	}
	catch (ex) {
		alert(ex);
	}
}


setting up the webservice proxy object works fine but any call to Echo
or Add results in the following error:

Error: [Exception... "Could not convert JavaScript argument arg 0
[TestServiceSoaphttp_003a_002f_002flocalhost_003a8080_002f1_002e1_002fwebservice_002fTestService_002easmx_003fwsdl_003d0Async.Add]"

I'm not sure if this is a problem with firefox or with xsp, the
attached code is exactly the same as in the example that mozilla show
where they access the Amazon web service:

Has anyone else had any luck accessing a webservice running under XSP
via javascript in mozilla? or should I post this on a mozilla mailing
list?
