Java unable to call socket service

So I have created a service on JDeveloper with socket adapter where a message is read from. I have followed the steps mentioned in the following link for that: https://shrikworld.blogspot.com/2014/11/demystifying-oracle-socket-adapter.html However the problem is that when i create the java class to test the service, i get an error.

I have been trying to figure out what the issue is but i cant find anything useful on this. Here is a description of the SocketAdapter in my weblogic console:

Host: localhost KeepAlive: true EnableSDP: false backlogQueue: 0 port: 12110 SSLEnable: false NeedClientAuthentication: false Timeout: 1000

Here is my java class:

1. import java.io.BufferedReader;
2. import java.io.IOException;
3. import java.io.InputStreamReader;
4. import java.io.OutputStream;
5. import java.net.Socket;
6. public class Client {
7.     public static void main(String[] args) {
8.         try {
9.             Socket socket;
10.             final String HOST = "localhost";
11.             final int PORT = 12110;
12.             try {
13.                 socket = new Socket(HOST, PORT);
14.             } catch (IOException ioe) {
15.                 System.out.println(">>>");
16.                 System.out.println(ioe.getMessage());
17.                 System.out.println(">>>");
18.                 throw ioe;
19.             }
20.             System.out.println("sending data: EmpDetails;");
21.             OutputStream os = socket.getOutputStream();
22.             byte[] b = "fn111111ln111111232007-01-01100\nfn211111ln211111232007-11-01200\nfn311111ln311111232007-12-01300".getBytes();
23.             for (int i = 0; i < b.length; i++) {
24.                 os.write(b[i]);
25.             }
26.             os.flush();
27.             socket.shutdownOutput();
28.             System.out.println("receiving data");
29.             BufferedReader soc_in = new BufferedReader(new InputStreamReader(socket.getInputStream()));
30.             String successCode = soc_in.readLine();
31.             System.out.println("Success Code: " + successCode);
32.             socket.close();
33.         } catch (IOException ioe) {
34.             ioe.printStackTrace();
35.         }
36.     }
37. }

and here is the error I get when I try running the code:
