Cannot read more than twice on BufferedReader/Inputstream

[Amit Shef]

As the title says i cannot read more than twice.
I can read the first line and than on the second time and on its giving me an exception.

Server:

 public static void main(String[] args){
try {
serverSocket = new ServerSocket(PORT);
} catch (IOException e) {
System.out.println("Could not listen on port: PORT");
}
System.out.println("Server started and now Listening to the port PORT");
while (true) {
try {
clientSocket = serverSocket.accept();
clientList.add(clientSocket);
System.out.println(clientSocket);
System.out.println("ACCEPTED");
inputStreamReader = new InputStreamReader(clientList.get(0)
.getInputStream());
bufferedReader = new BufferedReader(inputStreamReader);
inputStream = new ByteArrayInputStream(bufferedReader
.readLine().getBytes(Charset.forName("UTF-8")));
bufferedReader2 = new BufferedReader(new InputStreamReader(
inputStream));
output = bufferedReader2.readLine();
out = new PrintWriter(clientList.get(0).getOutputStream(), true);
System.out.println(output);
out.println(output);
out.flush();
out.close();
inputStreamReader.close();
clientSocket.close();
System.out.println("FINISHED");
} catch (IOException ex) {
System.out.println("Cannot read message");
}
}
}

Client:

try {
client = new Socket(
IP,
PORT);
} catch (UnknownHostException e) {
// TODO
// Auto-generated
// catch block
e.printStackTrace();
} catch (IOException e) {
// TODO
// Auto-generated
// catch block
e.printStackTrace();
}
try {
final Scanner in = new Scanner(
client.getInputStream());
} catch (IOException e) {
// TODO
// Auto-generated
// catch block
e.printStackTrace();
}
PrintWriter out = null;
try {
out = new PrintWriter(
client.getOutputStream());
} catch (IOException e) {
// TODO
// Auto-generated
// catch block
e.printStackTrace();
}
out.println(MESSAGE);
out.flush();
}

What is the exception?

[Amit Shef]

"Cannot read message"

[fred rosenberger]

That's not the exception. That's the String you print out when you catch the IOException.

Trying printing the actual stacktrace. It should at least help you figure out which line is causing hte issue.

[Amit Shef]

Socket is closed

[fred rosenberger]

I really know nothing about sockets and this kind of stuff, but if the problem is that the socket is closed, maybe you should not close it?

Your server code looks a bit complicated. Why create an InputStreamReader (line 18), then wrap that in a BufferedReader (line 20), then read a line from that into a ByteArrayInputStream (encoding it using UTF-8), and then reading that again with a different BufferedReader and InputStreamReader (line 23; using the default character encoding which is not necessarily UTF-8)? It looks much more complicated than necessary.

Look at what your server code does. It accepts a client connection, then reads one line, prints it back, and then closes the connection. There's no loop anywhere to handle multiple lines.

Can you explain more clearly what exactly you expected both the server and client programs to do, what they actually do, and what the difference is between what you expected and what actually happens?

I managed to work it
When i set up a loop on client the client always connected to the server with a new port or ip so it did not recognize the ip or port , Sorry if i can't explain it right.
Thanks anyway.
