Hi i have written a server program to receive ISO8583-93 version requests process them and send response.I will be receiving continuous requests.It works fine ,but if socket is idle when the next request comes, server is not reading. Please find below code snippet
SERVER :
public class MBServ {
public static void main(String[] args) throws IOException {
ServerSocket serverSocket = null;
boolean listening = true;
String request_date = null;
String request_time = null;
try {
serverSocket = new ServerSocket(7777);
} catch (IOException e) {
System.err.println("Could not listen on port: 7777.");
System.exit(-1);
}
while (listening) {
new MBServT(serverSocket.accept()).start();
}
serverSocket.close();
}
}THREAD:
public class MBServT extends Thread {
private Socket socket = null;
Logger log = Logger.getLogger(MBServT .class.getName());
public MBServT(Socket socket) throws FileNotFoundException, IOException {
super("MBServT");
this.socket = socket;
}
public void run() {
String inputLine = "";
String msgType = null;
int response = 12;
String outwardMsg = null;
BufferedReader buffReaderObj = null;
// String ip = "172.30.12.69";
String stanNo = "0";
boolean ISSUBFIELDPARSING = false;
GenericPackager packager;
try {
packager = new GenericPackager("basicparse.xml");
BufferedReader is = new BufferedReader(new InputStreamReader(socket
.getInputStream(), "ISO8859_1"));
BufferedWriter writer = new BufferedWriter(new OutputStreamWriter(
socket.getOutputStream(), "ISO8859_1"));
String strBuf = null;
int length = 4;
char[] chrBuf = new char[length];
int cnt = 0;
while (true) {
socket.setKeepAlive(true);
int value = 0;
int ret = 0;
ret = is.read(chrBuf, 0, chrBuf.length);
if (-1 == ret)
{
log.error("nothing to read closing socket");
try{
socket.close();
}
catch(Exception e){
System.out.println("Error in socket.close: " +e.toString());
}
throw new Exception("Read Error: Socket closed");
}
strBuf = new String(chrBuf);
chrBuf = new char[Integer.parseInt(strBuf)];
is.read(chrBuf, 0, chrBuf.length);
strBuf = new String(chrBuf);
chrBuf = null;
chrBuf = new char[4];
value = 0;
/*writing response*/
Runnable respThread = new MBServRespT(writer, fieldList,
"threadname");
((Thread) respThread).start();
}
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
System.out.println("Error::" + e.toString());
} finally {
try {
socket.close();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
