WCF and Json 404 Error
WCF and Json 404 Error
- I'm trying to call the WCF service(Different machine) from my local machine but no luck, returns 404
there may be simple things missing but as I'm new to this couldn't figure out.
1. WCFService.svc
namespace WCFTest
{
public class WCFService : IWCFService
{
public string HelloWorld(string strName)
{
return "Your Entered:"+strName;
}
}
}
2. WCFService.svc.cs
namespace WCFTest
{
[ScriptService]
public class WCFService : IWCFService
{
public string HelloWorld(string strName)
{
return "Your Entered:"+strName;
}
}
}
3. webconfig
<system.serviceModel>
<bindings>
<webHttpBinding>
<binding name="jsonBinding" maxReceivedMessageSize="2147483647">
</binding>
</webHttpBinding>
</bindings>
<services>
<service behaviorConfiguration="WCFTest.WCFServiceBehavior" name="WCFTest.WCFService">
<endpoint address="http://server:portnumber/WCFService.svc" binding="webHttpBinding" bindingConfiguration="jsonBinding" behaviorConfiguration="jsonBehavior" name="myservice" contract="WCFTest.IWCFService">
</endpoint>
</service>
</services>
<behaviors>
<serviceBehaviors>
<behavior name="WCFTest.WCFServiceBehavior">
<serviceMetadata httpGetEnabled="true"/>
<serviceDebug includeExceptionDetailInFaults="false"/>
</behavior>
</serviceBehaviors>
<endpointBehaviors>
<behavior name="jsonBehavior">
<enableWebScript/>
</behavior>
</endpointBehaviors>
</behaviors>
</system.serviceModel>
** The service is deployed on the server.
4. Created Defalut.aspx on my local machine
<body onload="Initialize();">
<form id="form1" runat="server">
<asp:ScriptManager ID="ScriptManager1" runat="server" EnablePageMethods="true">
<Services>
<asp:ServiceReference Path="http://server:portnumber/WCFService.svc"/>
</Services>
<Scripts>
<asp:ScriptReference Path="~/test.js"/>
</Scripts>
</asp:ScriptManager>
<div>
<label>Greetings:</label><asp:Label ID="lblShow" runat="server"></asp:Label>
</div>
</form>
</body>
5. Created test.js on my local machine
function Initialize() {
var proxy = new WCFTest.IWCFService();
proxy.HelloWorld("YOurName",OnSuccess, OnFailure);
}
function OnSuccess(result) {
document.getElementById('lblShow').innerHTML = result;
}
function OnFailure(result) {
alert('Failed');
}
6. Result: "The server method 'HelloWorld' failed."

- Hi ,
The 404 or Not Found error message is a HTTP standard response code indicating that the client was able to communicate with the server but the server could not find what was requested.
Please have a look at this code sample about one REST Model WCF service for your reference. ScriptService should be used in previous Web Service technology.
