Ajax WCF Restful Service Call Return Blank Page

I am attempting to call a wcf rest service via ajax construct using jquery, however i am getting a bad request error when doing so from the jquery. Also, I try to browse directly to the service and receive a blank page. I have done WCF service calls before in the past and cannot figure out what is wrong here. Thanks in advance to all that reply. When browsing directly to the service I see no results. Here is the jquery ajax code that makes the call:

$.ajax({ type: "GET", dataType: "json", contentType: "application/json; charset=utf-8", url: "http://localhost:57452/mobile/WCFService/ContactService.svc/hello", success: function (result) { alert('success'); }, error: function (result) { alert(result.status + ' ' + result.statusText); }

    });

Here is the service interface:

[ServiceContract]
    public interface IContactService
    {
        [OperationContract]
        [WebGet(
            ResponseFormat = WebMessageFormat.Xml,
            BodyStyle = WebMessageBodyStyle.Wrapped,
            UriTemplate = "hello")]
        string SaySomething();

    }

Here is the service class:

 [AspNetCompatibilityRequirements(RequirementsMode =      AspNetCompatibilityRequirementsMode.Allowed)]
    public class ContactService : IContactService
    {
        public string SaySomething()
        {
            // Add your operation implementation here
            return "Hello!";
        }
    }

Here is the configuration for the service in the web.config file:

<system.serviceModel>
    <serviceHostingEnvironment aspNetCompatibilityEnabled="true" />
    <behaviors>
      <serviceBehaviors>
        <behavior name="SomeNameSpace.mobile.WCFService.ContactServiceBehavior">
          <serviceMetadata httpGetEnabled="true" />
          <serviceDebug includeExceptionDetailInFaults="false" />
        </behavior>
      </serviceBehaviors>
    </behaviors>
    <services>
      <service behaviorConfiguration="LeeCounty_ASP.mobile.WCFService.ContactServiceBehavior"
        name="SomeNameSpace.mobile.WCFService.ContactService">
        <endpoint address="" binding="wsHttpBinding" contract="SomeNameSpace.mobile.WCFService.IContactService">
          <identity>
            <dns value="localhost" />
          </identity>
        </endpoint>
        <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
      </service>
    </services>
  </system.serviceModel>

I found the issue. It appears that when adding a wcf service, the default bindings added to the config file did not add the webHttpBinding. Found the solution from this link, http://www.codeproject.com/Articles/132809/Calling-WCF-Services-using-jQuery
