Unable to connect to internet, Connection Refused

I have a massive problem. I am unable to connect to a Java server-socket from the android emulator. I have got the log and code:

I am using a version 2.1 (Eclair) emulator to run my android application.

System.out.println("Sup");
try{
    Socket socket = new Socket("127.0.0.1", 26753);
    PrintWriter out = new PrintWriter(socket.getOutputStream(), true);
    out.println("e:ask");
    out.println("p:pass");
    out.println("EOF");
    socket.close();
} catch (Exception e){
    e.printStackTrace();
}

Logcat errors:

Do I need more permissions?

first of all make sure you put internet permission in your manifest file, and then make sure your host and port number are all correct, and lastly check that you have right to access that host+port.

127.0.0.1 is the ip of the emulator. 10.0.2.2 is what you are looking for (the host the emulator is running on)
