Hello guys and girls,

 I'm used to programming mainly in Java and I'm finding it hard to find enough documention on things to get basic

functionality working.  I created a simple Handler in Asp.net using C# and I'm using basically the same script

as shown in the example code they offer.   

 The Handler is located at:

http://www.ulrpg.com/MYSPACETEST/Handler.ashx?command=getKingdom
 

if you type that in as is, you'll see you get the response "Helsinc" as expected.  But how do I pass that back 

to my myspace app?  Here is the code I am attempting to use in the script: 

<script>   
function init()
    {
        var url = "http://www.ulrpg.com/MYSPACETEST/Handler.ashx?command=getKingdom";
                
        os_params = {};
        
        opensocial.makeRequest(url, makeRequest_Callback, os_params);
        
        function makeRequest_Callback(data){
            
            var responseText = data.responseText;
            alert(responseText);
        }
    }

init();
</script>

---------------

And here is my simple Handler code for testing purposes:

-----------------

<%@ WebHandler Language="C#" Class="Handler" %>

using System;
using System.Web;
using System.Web.Script.Serialization;
using System.Text;

public class JSonDreamResponse
{
    public string ErrorMessage;
    public bool HadError;
    public string ResponseMessage;
}

public class Handler : IHttpHandler {
    


    public void ProcessRequest(HttpContext context)
    {
        string command = context.Request["command"];

        switch (command)
        {
            case "getKingdom":
                {
                    GetKingdom(context);
                    break;
                }
            default:
                {
                    throw new ApplicationException("Command: " + command + " is not supported");
                }
        }

        context.Response.ContentType = "text/html";
        context.Response.Cache.SetExpires(DateTime.Now.AddYears(1));

    }


    private void WriteToOutput(HttpContext context, String output)
    {
        context.Response.Write(output);
    }


    private void WriteError(HttpContext context, string message){

    }

    public void GetKingdom(HttpContext context)
    {
        try
        {
            String helsinc = "Helsinc";
            WriteToOutput(context, helsinc);

        }
        catch (Exception exc)
        {
            WriteError(context, exc.ToString());
        }
    }
    
 
    public bool IsReusable {
        get {
            return false;
        }
    }

}

-------------------------------------------------------

I keep getting returned the value "undefined" in the alert box.  Any help would be much appreciated. 

Well after spending all day, I finally started to figure things out and now I have it responding properly.

I found an excellent site that is descriptive and well written at: 

http://code.google.com/apis/opensocial/articles/makerequest.html 

The solution is to do something like the following:

<script>
function init()
{

function makeRequest(url) {
  var params = {};
  params[gadgets.io.RequestParameters.METHOD] = gadgets.io.MethodType.GET;
  gadgets.io.makeRequest(url, response, params);
};

function response(obj) {
  alert(obj.text);
};
makeRequest("http://www.ulrpg.com/MYSPACETEST/Handler.ashx?command=getKingdom");
}
    init();
</script>
