Hi All,
Please bare with me. This is my first go on the Google app Engine:)
I'm having a lot of problems calling a Java based Google App Engine server from a C# client
This is how my client code looks like:
// C# Client
static void Main(string[] args)
{
const string URL = "http://localhost:8888/googlewebapptest7/greet";
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(URL);
request.Method = "POST";
request.ContentType = "text/x-gwt-rpc; charset=utf-8";
string content = "<?xml version='1.0'?><methodCall><methodName>greetServlet.GetName</methodName><params></params></methodCall>";
byte[] contentBytes = UTF8Encoding.UTF8.GetBytes(content);
request.ContentLength = contentBytes.Length;
using (Stream stream = request.GetRequestStream())
{
stream.Write(contentBytes, 0, contentBytes.Length);
}
// get response
WebResponse response = request.GetResponse();
using (Stream responseStream = response.GetResponseStream())
{
string res = new StreamReader(responseStream).ReadToEnd();
Console.WriteLine("response from server:");
Console.WriteLine(res);
Console.ReadKey();
}
The server is basically the Google default web project with an additional method:
public String GetName()
{
return "HI!";
}
added to GreetingServiceImpl.
Everytime I run my client, I get the following exception from the server:
An IncompatibleRemoteServiceException was thrown while processing this call.
com.google.gwt.user.client.rpc.IncompatibleRemoteServiceException: This application is out of date, please click the refresh button on your browser. ( Malformed or old RPC message received - expecting version 5 )
I would like to keep it in plain HTTP requests.
Any idea what's going on? -Any help would be much appreciated!
