Hi,
I have a problem when sending data over TCP socket from c# client to java
server.
the connection established ok, but i can't send data from c# client to java
server.
it's work ok with TcpClient, NetworkStream and StreamWriter classes.
but with low level socket it doesn't work (When using the Socket class Send
method).
here is the sample code (c# and java):
===========
C# Code
===========
public static void RunSocketTcpClient()
{
Socket sock = new Socket(AddressFamily.InterNetwork, SocketType.Stream,
ProtocolType.Tcp);
IPEndPoint iep = new IPEndPoint(IPAddress.Parse("127.0.0.1"), 8080);
byte[] data = new byte[1024];
string stringData;
int recv=0;
sock.Connect(iep);
data = Encoding.ASCII.GetBytes("Hello");
sock.Send(data, data.Length, SocketFlags.None);
}
=================
The Java code
=================
//: c15:JabberServer.java
// Very simple server that just
// echoes whatever the client sends.
// {RunByHand}
import java.io.*;
import java.net.*;
public class JabberServer {
// Choose a port outside of the range 1-1024:
public static final int PORT = 8080;
public static void main(String[] args)
throws IOException {
ServerSocket s = new ServerSocket(PORT);
System.out.println("Started: " + s);
try {
// Blocks until a connection occurs:
Socket socket = s.accept();
try {
System.out.println(
"Connection accepted: "+ socket);
BufferedReader in =
new BufferedReader(
new InputStreamReader(
socket.getInputStream()));
// Output is automatically flushed
// by PrintWriter:
PrintWriter out =
new PrintWriter(
new BufferedWriter(
new OutputStreamWriter(
socket.getOutputStream())),true);
while (true) {
String str = in.readLine();
if (str.equals("END")) break;
System.out.println("Echoing: " + str);
out.println(str);
}
// Always close the two sockets...
} finally {
System.out.println("closing...");
socket.close();
}
} finally {
s.close();
}
}
} ///:~
Thanks.
