In my project I need to make a socket connection, however I realized that there is a chance that the user will not start the server. When this happens, it is obvious that the client will not be able to connect to the server. I wanted my application to be able to handle this exception. However, it seems that processing is unable to “catch” the exception.

my code:

```auto
  try {
      myClient = new Client(this, "127.0.0.1", 8000);
  } catch (Exception e) {
      //print(e);
      print("I stopped by to say hi!!!");
      exit();
  }

```

what the processing terminal returns is this:

```auto
java.net.ConnectException: Conexão recusada (Connection refused)

**My question is:**

> What am I doing wrong?
