Hi Sojan !
Server work,
but when run behind proxy=Exception.
Hier is part of code.
public static final int PORT=780;//port number
static Socket soc;
PrintWriter out;
BufferedReader in;
static boolean flag;//check connection
try{
ServerSocket ss=new ServerSocket(PORT);
flag=true;
while(flag){
soc=ss.accept();
v.in=new BufferedReader(new InputStreamReader(soc.getInputStream()));
Thread d=new Thread(v);
d.start();
}catch(Exception z){z.toString();
public void run() {
try{
while(flag){
String g="";
g=in.readLine();
if(g==null){break;}
//System.out.println(g);
jTextArea1.append(g+"\n");
catch(Exception c){
System.out.println("soc2 closed");
try{
soc.close();
}catch(IOException f){System.out.println("soc2 not closed");}
