I have this stadard code for receiving a class from a web service: 

```

function getStuff() {
  var callParams = "{'param1':'" + "oren"  + "'}"
  $.ajax({
  type: "POST",
  url: "http://192.168.5.223:8989/TolunaAPI.asmx/GetDummyType",
  data: callParams,
  contentType: "application/json; charset=utf-8",
  dataType: "json",
  success: function (data) {
    alert(data);
  ....

```

This give an alert that says: [object Object].  

I tried reading some related posts here and on JQuery documentation, but I can't understand what exactly is the "data" object.  

What the web service returns is and object named DummyType:

```

public class DummyType
    {
       public ErrorTypes error;
       public NestedDummyType nested;
       public DummyType() { }
       public DummyType(string paramName)
       {
           error = ErrorTypes.None;
           nested = new NestedDummyType();
       }
    }
}

```

Which as you see has another object in it, namely NestedDummyType:

```

public class NestedDummyType
    {
       public string nestedString;
       public int nestedInt;
       public NestedDummyType()
        {
            nestedString = "Hello from nested";
            nestedInt = -1;
        }
    }

```

All of these are supposed to be returned in json format, but as mentioned, I can't seem to be able to interpret the received data.  

How is this done?  

Thanks.
