    我现在在做面向服务的解决方案，故我把WCF项目作为一个单独的Service项目，WEB应用程序通过xx.svc去调用服务，但是页面jQuery总是请求失败。
    WEB程序命名空间是jQueryCallWcf.Web，WCF Service命名空间是：jQueryCallWcf.Service，在WEB应用程序中添加了AjaxService3.svc（单独文件，没有cs后置代码），指定Service="jQueryCallWcf.Service.AjaxService2"，jQueryCallWcf.Service.AjaxService2是WCF的实现。在页面ajax请求中指定url为AjaxService3.svc/GetObject，ajax报415错误。
    请高手指教错误之处。

    WCF项目：
    IAjaxService2 契约：

    using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.ServiceModel;
using System.ServiceModel.Web;
using System.ServiceModel.Activation;

namespace jQueryCallWcf.Service {
    [ServiceContract(Namespace = "")]
    public interface IAjaxService2 {
        [OperationContract]
        [WebInvoke(Method = "POST", ResponseFormat = WebMessageFormat.Json)]
        string[] GetNames(string a);

        [OperationContract]
        [WebInvoke(Method = "POST", ResponseFormat = WebMessageFormat.Json)]
        object GetObject();
    }
}

    AjaxService2 实现：

    using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.ServiceModel.Activation;
using Newtonsoft.Json;

namespace jQueryCallWcf.Service {

    [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
    public class AjaxService2 : IAjaxService2 {

        public string[] GetNames(string a) {
            return new string[] { "John", "Willim", "Sonny", "Allen" };
        }

        public object GetObject() {
            var a = new {
                Name = "John",
                Age = 23,
                Address = "shanghai",
                Born = new DateTime(1980, 10, 20)
            };
            string str = JsonConvert.SerializeObject(a);
            return str;
        }
    }
}


    WEB应用程序：
    请求页面：

        </services>
    </system.serviceModel>
    <system.web>
        <compilation debug="true"/>
    </system.web>
</configuration>

    WEB应用程序中的svc，WEB项目添加了Service项目的引用

    <%@ ServiceHost 
    Language="C#" Debug="true" 
    Service="jQueryCallWcf.Service.AjaxService2,
            jQueryCallWcf.Service, 
            Version=1.0.0.0, 
            Culture=neutral, 
            PublicKeyToken=null" %>

    但是请求就是不成功。

    请教：
    1.为什么请求会失败，该如何解决？
    2.面向服务的解决方案是不是WCF应该作为单独的WEB项目，比如应用程序是http://localhost:8000，WCF服务http://localhost:8001/AjaxService2.svc。WEB和Service之间没有引用关系？那该怎么做？
    我的示例在：http://dl.vmall.com/c0mw0cveqr，见jQueryPage3.aspx页面。
