Problem with simple Java network program
Hello,
I was just trying a simple program to get reply from the Server. I need some help with it.
Here is the Server code -
Code:
package simpleprograms;
import java.net.Socket;
import java.net.ServerSocket;
import java.io.PrintWriter;
public class ListeningServer {
public static void main(String[] args) {
try {
//InetSocketAddress addr=new InetSocketAddress(7);
ServerSocket servsock = new ServerSocket(7800);
Socket sock;
PrintWriter pw;
if(servsock.isBound()) {
System.out.println("Server at " + servsock.getInetAddress() +
" is listening on port " + servsock.getLocalPort());
}
else {
System.out.println("Bind Error");
//exit(1);
}
while (true) {
sock = servsock.accept();
pw=new PrintWriter(sock.getOutputStream());
pw.println("Hello");
sock.close();
}
} catch (Exception ex) {
ex.printStackTrace();
}
}
}
Here is the client program -
Code:
package simpleprograms;
import java.io.DataInputStream;
import java.io.IOException;
import java.net.Socket;
import java.net.UnknownHostException;
public class PingServer {
public static void main(String[] args) {
try {
Socket t = new Socket("127.0.0.1", 7800);
DataInputStream dis = new DataInputStream(t.getInputStream());
byte[] b = new byte[1024];
dis.read(b);
String str = new String(b);
System.out.println(str);
if (str.equals("Hello")) {
System.out.println("Alive");
} else {
System.out.println("Dead");
}
t.close();
}
catch(UnknownHostException ex) {
System.out.println(ex.toString());
}
catch(IOException ex) {
System.out.println(ex.toString());
}
catch (Exception ex) {
//System.out.println(ex.toString());
ex.toString();
}
}
}
When I run the Server and the Client, I get the O/P from the Server as -
Dead |
