"statement cannot reached " error?

Question

Hi,
I have a question regarding client-server . I am sending message to Server from Client. But I don't know how many messages come to Client from Server. I'm getting all messages from server,but couldn't send message again to server.
I 'm getting error like "Statement not reached ". can anyone rectify my code and give solution. I understand the error, but couldn't get correct solution.
here is my code for client and server :
import java.io.*;
import java.net.*;
class TestClient {
     public static void main (String argv[]) throws Exception
          Socket client_sock = new Socket ("localhost", 3000);
          DataOutputStream toServer =
               new DataOutputStream (client_sock.getOutputStream ());
    BufferedReader fromServer =
               new BufferedReader (new InputStreamReader (
                    client_sock.getInputStream ()));
          BufferedReader fromKeybd =
               new BufferedReader (new InputStreamReader (System.in));
          try {
               while (true) {
        System.out.print(" Enter some string for testing connection : ");
        // reading input and sending msg to Server.
        String str = fromKeybd.readLine();
        toServer.writeBytes(str+'\n');
        while(true)
          System.out.println(" "+fromServer.readLine());
        } // end of while
       String msg = " hai";
       toServer.writeBytes(msg+'\n');
          } // end of while
          } catch (EOFException eof)
     { System.err.println(eof.getMessage());
          finally {
                    client_sock.close();
          }  // end of finally
     } // end of main
import java.io.*;
import java.net.*;
import java.util.*;
class TestServer {
     public static void main (String argv[]) throws Exception
    ServerSocket baseSocket =  new ServerSocket (3000);
          Socket connectedSocket = baseSocket.accept ();
          while (true) {
    try{
               BufferedReader fromClient = new BufferedReader (
                    new InputStreamReader (connectedSocket.getInputStream()));
               DataOutputStream toClient =new DataOutputStream (
                    connectedSocket.getOutputStream ());
      String str;
      // getting msg from client
         str = fromClient.readLine ();
      System.out.println(" from Client - connection testing :"+str);
      int rand = (int)(Math.random() * 10);
      System.out.println(" random no "+ rand);
      for ( int i=0;i<rand;i++)
         // sending iterations no to Client randomly.
         toClient.writeBytes(" iterations : "+i+'\n');
       String msg ;
        msg = fromClient.readLine();// getting msg from client.
      System.out.println(" from Client : "+msg);
     }catch(IOException ioe)
      System.err.println(ioe.getMessage());
     catch(Exception e)
      System.err.println(e.getMessage());
          } // end of while
     } // end of main
}Thanks in advance,

while((fromServer.readLine()) != null))
System.out.println(" "+fromServer.readLine());
} // end of while
String msg = " hai";
toServer.writeBytes(msg+'\n');
In that code, what happens after printing the message received from the server? It goes to the top of the loop. How do you expect the code that comes outside of the loop to be executed? Sure, the loop ends when the stream detects loss of connection, but that's too late!
