Hello!
Can anyone tell me why I'm getting a "Connection refused" exception?

I have clent and server were written in Delphi 3.0. They communicate
themself with sockets. Now I am  writing a client (Java applcation) in
JBulder2.0 and this client must connect to Delphi server. But when I try
to create a socket object I'm getting a "Connection refused" exception.
I'm running on a  WinNT4.0 machine with TCP/IP installed and
functioning. Delphi server listened for socket connections over TCP/IP.
Java client is working right when I connect to ports such 22, 23, 25,
...and other  but it doesn't work when it conects to Delphi server's
port. And when I write a simple server on Java the client also is
working. May be I must config any parameters?


     InetAddress Naddr = InetAddress.getByName(LogOnHost);
      try
      {
      Socket socket = new Socket(Naddr,Nport);
      ..........
      socket.close();
      }
      catch(IOException IOex)
      {
        System.out.println("IOex: " + IOex);
      }

Thank,

Rustam
