Hi all,
I have a problem with reading from a Java server after I have written
to it - it just hangs. It works fine if I just write to the server and
not try to write. I have read the HOWTO on sockets - and it states
that there is a problem (something about flushing), but not what the
solutions is. Nor do google. Can somebody please help?
A few lines down you can see the example code that sums up the
problem. Just change the name of the Python HOST-variable.
Thanks
Mads
This is the client in Python:
#! /usr/bin/env python
import sys
from socket import *
PORT = 3122
HOST = 'app-5'
SUCCESS = 'Success'
FAILURE = 'Failure'
s = socket(AF_INET, SOCK_STREAM)
s.connect((HOST, PORT))
s.send("Hi Java Server");
print "Have written, waiting to recieve.."
print s.recv(1014)
s.close()
And this the server in Java:
import java.io.*;
import java.net.*;
public class Server{
public static void main(String args[]){
int port = 3122;
int backLog = 50;
ServerSocket ss = null;
try{
InetAddress localhost =
InetAddress.getLocalHost();
ss = new ServerSocket(port, backLog,
localhost);
while(true){
final Socket client = ss.accept();
new Thread(){
public void run(){
try{
InputStream is =
client.getInputStream();
BufferedReader buf =
new BufferedReader(new InputStreamReader(is));
print(buf.readLine());
PrintWriter out = new
PrintWriter(client.getOutputStream());
out.write("Hi Python
Client.");
out.flush();
client.close();
}catch(Exception e)
{print(e);}
}
}.start();
}
}catch(Exception e){print(e);}
}
private static void print(Object o){System.out.println(o);}
}
