Getting Started with Tyrus: A Quick Example

Alright, enough theory! Let's get our hands dirty and see how to use Tyrus in a simple example. We'll create a basic WebSocket server and client to demonstrate the fundamental concepts.

Setting Up Your Project

First, you'll need to set up a Java project and include the necessary Tyrus dependencies. You can use Maven or Gradle to manage your dependencies. Here's a Maven snippet:

<dependency>
    <groupId>org.glassfish.tyrus</groupId>
    <artifactId>tyrus-server</artifactId>
    <version>1.17</version>
</dependency>
<dependency>
    <groupId>org.glassfish.tyrus</groupId>
    <artifactId>tyrus-client</artifactId>
    <version>1.17</version>
</dependency>

Make sure you have the tyrus-server and tyrus-client dependencies in your project.

Creating a Simple WebSocket Server

Now, let's create a simple WebSocket server endpoint. This endpoint will receive messages from clients and echo them back.

import javax.websocket.*;
import javax.websocket.server.ServerEndpoint;

@ServerEndpoint("/echo")
public class EchoServer {

    @OnOpen
    public void onOpen(Session session) {
        System.out.println("Client connected: " + session.getId());
    }

    @OnMessage
    public void onMessage(String message, Session session) throws IOException {
        System.out.println("Received message: " + message);
        session.getBasicRemote().sendText("Echo: " + message);
    }

    @OnClose
    public void onClose(Session session) {
        System.out.println("Client disconnected: " + session.getId());
    }

    @OnError
    public void onError(Throwable error) {
        error.printStackTrace();
    }
}

In this code:

  • @ServerEndpoint("/echo") defines the WebSocket endpoint at the /echo path.
  • @OnOpen is called when a client connects to the endpoint.
  • @OnMessage is called when the server receives a message from a client.
  • @OnClose is called when a client disconnects.
  • @OnError is called when an error occurs.

Creating a WebSocket Client

Next, let's create a simple WebSocket client to connect to the server and send messages.

import javax.websocket.*;
import java.net.URI;

@ClientEndpoint
public class EchoClient {

    private Session session;

    @OnOpen
    public void onOpen(Session session) {
        this.session = session;
        System.out.println("Connected to server: " + session.getId());
    }

    @OnMessage
    public void onMessage(String message) {
        System.out.println("Received message: " + message);
    }

    @OnClose
    public void onClose() {
        System.out.println("Disconnected from server");
    }

    @OnError
    public void onError(Throwable error) {
        error.printStackTrace();
    }

    public void sendMessage(String message) throws IOException {
        session.getBasicRemote().sendText(message);
    }

    public static void main(String[] args) throws Exception {
        WebSocketContainer container = ContainerProvider.getWebSocketContainer();
        String uri = "ws://localhost:8080/echo";
        try {
            EchoClient client = new EchoClient();
            container.connectToServer(client, new URI(uri));
            client.sendMessage("Hello, Server!");
            Thread.sleep(1000);
        } finally {
            // Keep the program running to receive messages
            Thread.sleep(5000);
        }
    }
}

In this code:

  • @ClientEndpoint marks this class as a WebSocket client endpoint.
  • @OnOpen is called when the client connects to the server.
  • @OnMessage is called when the client receives a message from the server.
  • sendMessage sends a message to the server.

Running the Example

  1. Deploy the Server: Deploy the EchoServer to a Java EE container like Tomcat or GlassFish. Make sure your server is running on localhost:8080.
  2. Run the Client: Run the EchoClient as a Java application.

You should see the client connect to the server, send a message, and receive an echo response. This simple example demonstrates the basic steps involved in building WebSocket applications with Tyrus.
