json is not serialized in order format

[Rajeshkumar123]

I tried your class for serializing the object to XML. I am facing one problem. While serializing my xml tags are not in order format. Due to that I am getting error when I try to send the SOAP request.

My wrapper class

public class FedexRequestJSON {
	public cls_ProcessShipmentRequest ProcessShipmentRequest;
    
	public class cls_ProcessShipmentRequest {
		public cls_WebAuthenticationDetail WebAuthenticationDetail;
		public cls_ClientDetail ClientDetail;
		public cls_TransactionDetail TransactionDetail;
		public cls_Version Version;
		public cls_RequestedShipment RequestedShipment;
	}
}

My Output on JSON Serialize(I didn't post the complete output just a sample to show how the order was changed)

{
  "ProcessShipmentRequest" : {
    "WebAuthenticationDetail" : {
      "UserCredential" : {
        "Password" : "**",
        "Key" : "***"
      }
    },
    "Version" : {
      "ServiceId" : "ship",
      "Minor" : 0,
      "Major" : 23,
      "Intermediate" : 0
    },

Is it possible to serialize the same order like in Wrapper class order.

Is there any reason why the order matters?

It matters sometimes. Some services are with a setting that you must follow the order of elements strictly or it returns an error like "Expected element xxxxx instead of xxxxx". It would be a great improvement to save time not having to do a sort after call your utility.

You saved me a lot of time with this utility classes. Thank you so much @skolakan !!
