Calling Web Service from ASP.NET AJAX

[NBD]

Hi,

I am getting a 'web service undefined' error when calling a web service from
Javascript which I've defined inside the ScriptManager tag like so:

<asj:ScriptManager ID="ScriptManager1" runat="server">
<Services>
<asj:ServiceReference Path="~/Services/MyWS.asmx" InlineScript
="True" />
</Services>
</asj:ScriptManager>

I'm calling the service from Javascript function like so:

function CallWS()
{
Namespace.MyWS.MyMethod(var);
}

The error message says that the class is 'undefined'. I've tried different
variations of namespaces and class names but no dice..

Any help is appreciated.

Thanks,

NBD

I used Fiddler to catch the network messages and I got this:


System.InvalidOperationException: jsdebug Web Service method name is not
valid.
at System.Web.Services.Protocols.HttpServerProtocol.Initialize()
at System.Web.Services.Protocols.ServerProtocolFactory.Create(Type type,
HttpContext context, HttpRequest request, HttpResponse response, Boolean&
abortProcessing)

The method is pretty straigthforward - three ByVal input params (all string
type). I have also set the attribute of the class to <ScriptService()> _

Would anyone know why the method name is not valid?
