Problem in sockets

hi i am trying to buid a server socket and a client socket which would communicate with each other,.. i build the following code but its i am getting no reponse from either side.. The only output i got is shown at the end..There is no error reported from the compiler either .. please can anyone figure out how to correct it?

CLIENTSOCKET:



import java.io.;
import java.net.;
public class client3
{
public static void main(String args[])
throws IOException,UnknownHostException
{
Socket client_socket = new Socket("localhost",9882);
int rp = client_socket.getPort();
System.out.println("Client connected to server at port:"+rp);
PrintWriter out = new PrintWriter(client_socket.getOutputStream());
BufferedReader in = new BufferedReader(new InputStreamReader(client_socket.getInputStream()));
out.println("Hi,i am client connected to you server");
String str1 = new String();
String str1 = in.readLine();
//out.println(str1);
System.out.println(str1);
in.close();
out.close();
client_socket.close();
}

}
OUTPUT:

Client connected to server at port:9882




SERVER SOCKET:

import java.net.;
import java.io.;
public class server3
{
public static void main(String args[])
throws IOException
{
Socket client_socket = null;
ServerSocket server_socket = new ServerSocket(9882);
System.out.println("Server ready,waiting for client: ");
client_socket = server_socket.accept();


//int t=client_socket.getSoTimeout();
//System.out.print(t);

PrintWriter out = new PrintWriter(client_socket.getOutputStream());
BufferedReader in = new BufferedReader(new InputStreamReader(client_socket.getInputStream()));
out.println("Hi,this is Server Speaking");
String c = in.readLine();
String str = new String();
while(c!=null)
{
str=in.readLine();
}
out.println("hi! this is Server , I received the followng message from you:");
out.println(str);
System.out.println(str);
out.close();
in.close();
client_socket.close();
server_socket.close();

}


}

OUTPUT:

Server ready,waiting for client:

I ran into this recently... you might need to flush the inputwriter first in order to actually send your text
