I suggest you implement your own server in Processing and talk to it through the Arduino

check the following code:

import processing.net.*;
Server myServer;

void setup() {
  size(200, 200);
  // Starts a myServer on port 1234, change this to whatever suits you!
  myServer = new Server(this, 1234); 
}

void draw() {
  // Get the next available client
  Client thisClient = myServer.available();
  // write the output of the client
  if (thisClient !=null) {
    String whatClientSaid = thisClient.readString();
    if (whatClientSaid != null) {
      println(thisClient.ip() + "t" + whatClientSaid);
    } 
  } 
}

and the Arduino code (for Ethernet example, easy to adopt):

#include <SPI.h>
#include <Ethernet.h>

// Enter a MAC address and IP address for your controller below.
// The IP address will be dependent on your local network:
byte mac[] = {  
  0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED };
IPAddress ip(192,168,1,177);

// Enter the IP address of the server you're connecting to:
IPAddress server(192,168,1,1); 

// Initialize the Ethernet client library
// with the IP address and port of the server 
EthernetClient client;

void setup() {
  // start the Ethernet connection:
  Ethernet.begin(mac, ip);
  // start the serial library:
  Serial.begin(9600);
  // give the Ethernet shield a second to initialize:
  delay(1000);
  Serial.println("connecting...");

  // if you get a connection, report back via serial:
  if (client.connect(server, 1234)) {
    Serial.println("connected");
  } 
  else {
    // if you didn't get a connection to the server:
    Serial.println("connection failed");
  }
}

void loop() {
  
  //The following code will simply send characters for Terminal input to the server - use it as a test
  while (Serial.available() > 0) {
    char inChar = Serial.read();
    if (client.connected()) {
      client.print(inChar); 
    }
  }

  // if the server's disconnected, stop the client:
  if (!client.connected()) {
    Serial.println();
    Serial.println("disconnecting.");
    client.stop();
    // do nothing:
    while(true);
  }
}
