as follows:

1. hosted WCF Service in IIS in name testWCF.
2. web application name is webWCF.

gave scriptreference as: http://localhost/testWCF/mywcf.svc

In JavaScript called the method GetSerivceCharge as

var y = x.GetSerivceCharge(res);
function res(result) {
    alert(result);
}

Microsoft JScript runtime error: Sys.Net.WebServiceFailedException: The server method 'GetSerivceCharge' failed with the following error: Not Found

Server Error in '/webWCF' Application.

Answer 1

Isn't this a cross domain issue? I see that your WCF web service is hosted in IIS and accessible through http://localhost/testWCF/mywcf.svc while your web application is using the ASP.NET development server which means it is hosted on http://localhost:SOME_PORT/webWCF.

AFAIK, AJAX is used when you want to invoke a web service from javascript. Due to cross domain restrictions you need to have the web service and the web application hosted on the same domain, or create a some proxy/bridge that will delegate calls to the web service.
