Java REST API to send and receive multiple String via socket server and get back the response from server

I am writhing a java socket API that is able to send sting to my socket server and get back the response from server.

Below is my server code :

package com.test.socket;

import java.io.*;
import java.net.*;
import java.util.Calendar;
public class Server
/** Instantiates an instance of the SimpleServer class and initilaizes it.
*/
public static void main(String args)
Server simpleserver = new Server();
simpleserver.init();


/** Sets up a ServerSocket and listens on port 8189.
*/
public void init()
ServerSocket serversocket = null;
Socket socket = null;
try
//establish a server socket monitoring port 8189
//port 8189 is not used by any services
serversocket = new ServerSocket(8189);
System.out.println("Listening at 127.0.0.1 on port 8189");

//wait indefinitely until a client connects to the socket
socket = serversocket.accept();

//set up communications for sending and receiving lines of text data
//establish a bufferedreaderr from the input stream provided by the socket object
InputStreamReader inputstreamreader = new InputStreamReader(socket.getInputStream());
BufferedReader bufferedreader = new BufferedReader(inputstreamreader);

//establish an printwriter using the output streamof the socket object
//and set auto flush on
PrintWriter printwriter = new PrintWriter(socket.getOutputStream(),true);

//for binary data use
// DataInputStream and DataOutputStream

//for serialized objects use
// ObjectInputStream and ObjectOutputStream

String datetimestring = (Calendar.getInstance()).getTime().toString();
printwriter.println("You connected to the Simple Server at " + datetimestring);

String lineread = "";
// boolean done = false;
while ((lineread = bufferedreader.readLine()) != null)
System.out.println("Received from Client: " + lineread);
printwriter.println(lineread);
// if (lineread.compareToIgnoreCase("Bye") == 0) done = true;


catch(UnknownHostException unhe)
System.out.println("UnknownHostException: " + unhe.getMessage());
catch(InterruptedIOException intioe)
System.out.println("Timeout while attempting to establish socket connection.");
catch(IOException ioe)
System.out.println("IOException: " + ioe.getMessage());





Below is my socket client function,that makes a connection to the socket server and fetches the response :

public Integer socketClient(String server_ip_address,String strToBeSent)

int serverport = 8189;
Socket socket = null;
InputStreamReader inputstreamreader = null;
BufferedReader bufferedreader = null;
PrintWriter printwriter = null;
int result=ConfigurationManager.FAILED_CODE;
try
System.out.println("Connecting to " + server_ip_address + " on port " + serverport);
socket = new Socket(server_ip_address,serverport);
//Set socket timeout for 10000 milliseconds or 10 seconds just
//in case the host can't be reached
socket.setSoTimeout(10000);
System.out.println("Connected.");

inputstreamreader = new InputStreamReader(socket.getInputStream());
bufferedreader = new BufferedReader(inputstreamreader);
//establish an printwriter using the output streamof the socket object
//and set auto flush on
printwriter = new PrintWriter(socket.getOutputStream(),true);
printwriter.println(strToBeSent);
String lineread = "";
while ((lineread = bufferedreader.readLine()) != null)
System.out.println("Received from Server: " + lineread);

result=ConfigurationManager.SUCCESS_CODE;

catch(UnknownHostException unhe)
System.out.println("UnknownHostException: " + unhe.getMessage());
result=ConfigurationManager.FAILED_CODE;
catch(InterruptedIOException intioe)
System.out.println("Timeout after communication via socket connection. Server Terminated");
System.out.println("Closing connection.");
result=ConfigurationManager.SUCCESS_CODE;
try
bufferedreader.close();
catch (IOException e)
// TODO Auto-generated catch block
e.printStackTrace();

try
inputstreamreader.close();
catch (IOException e)
// TODO Auto-generated catch block
e.printStackTrace();

printwriter.close();

catch(IOException ioe)
System.out.println("IOException: " + ioe.getMessage());
result=ConfigurationManager.FAILED_CODE;
finally
try
socket.close();
catch(IOException ioe)
System.out.println("IOException: " + ioe.getMessage());
result=ConfigurationManager.FAILED_CODE;


return result;



Now everytime,I run the program,although my string is sent 2 odd things are happening
1) my server automatically gets terminated. So after sending the frst string when I make make another call to my socketclient function to send the second string it gives me error as the server was terminated.
2) when ever I make a socketclient method call,although the string was sent to server and I get the response back. but the program reaches the catch block
catch(InterruptedIOException intioe){
System.out.println("Timeout after communication via socket connection. Server Terminated");
System.out.println("Closing connection.");

Instead of closing my socket normally.

Can I please have solution to this. How to resolve the server termination.
