Groovy Tcp client/server sending maps - groovy

I created a basic tcp client and server in groovy and I'm wanting to send maps from the server to the client, I'm wondering if I'm able send maps across and still being able to access the values.
//TCP Server
def book1 = [Title of Book: "Groovy Recipes", Author: "Scott Davis", Number of Pages: "241"]
server = new ServerSocket(2000)
println("Waiting for connection")
while(true) {
server.accept() { socket ->
socket.withStreams { input, output ->
w = new BufferedWriter(new OutputStreamWriter(output))
String message = "Connection was successful"
r = new BufferedReader(new InputStreamReader(input))
while(true) {
if(message != null) {
w.writeLine(message)
w.flush()
message = null
}
String a = r.readLine()
if(a=="book1") {
message = book1
} else {
message = "$a command unknown."
sendMessage(message)
println message
message = null
}
}
}
}
}
def sendMessage(String msg) {
try {
w.writeLine(msg)
w.flush();
} catch(IOException ioException) {
ioException.printStackTrace();
}
}
Here is my Client (where I'm wanting to receive the map and get the values)
//TCP Client
def grabBookInfo {
queryData()
}
public void queryData() {
def hosts = ["localhost"]
for(int aHost = 0; aHost < hosts.size; aHost++) {
bookClient(hosts[aHost]);
}
}
public void bookClient() {
def commands = ["book1"]
def answers = [commands.size]
def requestSocket = new Socket(host, 2000)
r = new BufferedReader(new InputStreamReader(requestSocket.getInputStream()));
w = new BufferedWriter(new OutputStreamWriter(requestSocket.getOutputStream()));
String message = "Connection was successful"
message = r.readLine()
println("Server>" + message)
for(int n = 0; n < commands.size; n++) {
sendMessage(commands[n]);
answers[n] = r.readLine()
}
//get map values here
//answers[0] = Book
//println Book.['Title of Book']
//println Book.['Author']
//println Book.['Number of Pages']
w.flush()
w.close()
}
public void sendMessage(msg) {
w.write(msg+"\r\n");
w.flush();
System.out.println("client>" + msg);
}
}
Am I on the right track?

In the server, use ObjectOutputStream.
In the client use ObjectInputStream.
Server:
private static final HashMap<String, Integer> TEST_MAP;
static {
TEST_MAP = new HashMap<String, Integer>();
TEST_MAP.put("one", 1);
TEST_MAP.put("two", 2);
}
...
ServerSocket ss = new ServerSocket(port);
Socket socket = ss.accept();
ObjectOutputStream out = new ObjectOutputStream(socket.getOutputStream());
out.writeObject(TEST_MAP);
out.close();
Client:
Socket socket = new Socket(HOST, PORT);
ObjectInputStream in = new ObjectInputStream(socket.getInputStream());
Object o = in.readObject();
assert o instanceof HashMap<?, ?>;
#SuppressWarnings("unchecked")
HashMap<String, Integer> m = (HashMap<String, Integer>)o;
assertTrue(m.get("one") == 1);
assertTrue(m.get("two") == 2);
in.close();
socket.close();

Get posted file over HTTP Listener in c#

I have make a simple http server using c#. And I know how to get posted data and output them. Here is my c# code
public static void start(){
HttpListener listener = new HttpListener();
listener.Prefixes.Add(new Uri("http://localhost:8080").ToString());
istener.Start();
while(true){
HttpListenerContext con = listener.GetContext();
showPostedData(con.Request);
con.Response.StatusCode = (int)HttpStatusCode.NotFound;
string data = "Uploaded successful";
byte[] output = Encoding.ASCII.GetBytes(data);
con.Response.ContentType = "text/html";
con.Response.ContentLength64 = output.Length;
con.Response.OutputStream.Write(output , 0, output.Length );
}
}
public static void showPostedData(HttpListenerRequest request){

System.IO.StreamReader reader = new System.IO.StreamReader(body, encoding);
string text;
if (request.ContentType != null)
{
text = reader.ReadToEnd();
}
Console.WriteLine( text );
}
My client html form has input box named file: <input type="file" name"file">
In the console output is like that :
file='Path of Choosed file not a file'
So How i get POSTED files and copy them to upload directory..?

ReceiveAsync from UDP socket

I want to create a UDP socket to receive data from Local Endpoint.
I do not know the Remote Port where data come from, that's why I thought I would use ReceiveAsync. But it does not work.
I give my code right now and any advice would be useful:
public class Program
{
ManualResetEvent clientDone;
Socket socket;
public static void Main(string[] args)
{
clientDone = new ManualResetEvent(false);
socket = new Socket( AddressFamily.InterNetwork, SocketType.Dgram, ProtocolType.Udp);
IPEndPoint localIPEP = new IPEndPoint( IPAddress.Any, 0);
socket.Bind( (EndPoint) localIPEP);
while (listening)
Receive();
}
string Receive()
{
string response;
byte[] recvData = new byte[24];
if (socket != null)
{
SocketAsyncEventArgs ae = new SocketAsyncEventArgs();
ae.SetBuffer(recvData, 0, recvData.Length);
// callback
ae.Completed += new EventHandler<SocketAsyncEventArgs>(delegate (object s, SocketAsyncEventArgs e)
{
if (e.SocketError == SocketError.Success)
{
response = Encoding.UTF8.GetString(e.Buffer, e.Offset, e.BytesTransferred);
response.Trim('\0');
}
else
{
response = e.SocketError.ToString();
}
switch (e.LastOperation)
{
case SocketAsyncOperation.Receive:
ProcessReceivedData(e);
break;
}
clientDone.Set();
});
clientDone.Reset();
Console.WriteLine("Local EndPoint: " + ((IPEndPoint)socket.LocalEndPoint).ToString());
socket.ReceiveAsync(ae);
clientDone.WaitOne(1000);
}
return response;
}
}

but with this code i am unable to obtain response as what the above wcf web service return
which is({"UserRegistrationResult":[{"OutputCode":"2","OutputDescription":"UserName Already Exists."}]})
Can anybody help me regarding its parsing in blackberry client end.
2.And the another code which i used is:

Please have the answer for my own question helps in parsing wcf rest services developed in .net and parsed at blackberry end.
This 2 classess definitely helps in achieving the above code parsing.
