Why not look at a confidential client and login using the client id and client secret

I tried following code:

> loginContext = new LoginContext("keycloak", new CallbackHandler() {
>      @Override
> public void handle(Callback[] callbacks) { int len = callbacks.length;
> Callback cb; for (int i = 0; i < len; i++) {
>      cb = callbacks[i];
>      if (cb instanceof NameCallback) { NameCallback ncb =
> (NameCallback) cb; ncb.setName(mdbuserName);
>      } else if (cb instanceof PasswordCallback) { PasswordCallback pcb
> = (PasswordCallback) cb; pcb.setPassword(mdbUsrPass);
>      }
> }
>      }
>  });
>  loginContext.login();


For following dependency issue while trying to login:
