What is Tyrus Websocket?

Tyrus Websocket is an implementation of the Java WebSocket API (JSR-356) that provides a standard way to establish a two-way communication channel between a client and a server over the web. It uses the WebSocket protocol (RFC 6455) to enable real-time communication between web applications and provides a set of APIs for developers to build WebSocket endpoints, client applications, and custom encoders/decoders.

Tyrus Websocket is an open-source project that is part of the GlassFish community and is available under the CDDL 1.1 license. It is actively maintained and updated by a team of contributors and supports the latest Java versions, including Java SE 8 and Java EE 7.

Features of Tyrus Websocket

Tyrus Websocket provides a range of features that make it an excellent choice for building real-time web applications. Here are some of its key features:

WebSocket API: Tyrus Websocket implements the Java WebSocket API (JSR-356), which provides a standard way to build WebSocket endpoints, client applications, and custom encoders/decoders.
Client and server support: Tyrus Websocket supports both client and server-side WebSocket communication, enabling bi-directional communication between web applications.
Custom encoders/decoders: Tyrus Websocket allows developers to create custom encoders/decoders to convert Java objects to/from WebSocket messages.
Programmatic and declarative endpoint configuration: Tyrus Websocket supports both programmatic and declarative (using annotations) endpoint configuration, making it easy to configure WebSocket endpoints.
Asynchronous messaging: Tyrus Websocket supports asynchronous messaging, allowing messages to be sent and received without blocking the thread.
SSL/TLS support: Tyrus Websocket supports SSL/TLS encryption for secure communication over the web.
WebSocket extensions: Tyrus Websocket supports WebSocket extensions, which provide additional functionality to the WebSocket protocol, such as compressing messages or adding custom headers.

How to use Tyrus Websocket

Now that you know what Tyrus Websocket is and its features, let’s see how to use it in your projects. Here are the steps to get started:

Step 1: Add Tyrus Websocket to your project

The first step is to add Tyrus Websocket to your project. You can use a build tool like Maven or Gradle to add the Tyrus Websocket dependency to your project. Here’s an example Maven dependency:

<dependency><groupId>javax.websocket</groupId><artifactId>tyrus-server</artifactId><version>1.13</version></dependency>

Make sure to use the latest version of Tyrus Websocket that is compatible with your Java version.

Step 2: Create a WebSocket endpoint

The next step is to create a WebSocket endpoint. An endpoint is a Java class that implements the javax.websocket.Endpoint interface and handles WebSocket communication. Here’s an example endpoint:

import javax.websocket.*;import javax.websocket.server.*;@ServerEndpoint("/echo")public class EchoEndpoint {
@OnMessagepublic void onMessage(String message, Session session) {try {session.getBasicRemote().sendText("Echo: " + message);} catch (Exception e) {e.printStackTrace();}}}

This endpoint listens on the “/echo” URI and echoes back any message it receives. The @ServerEndpoint annotation specifies the URI, and the @OnMessage annotation specifies the method to handle incoming messages. The method takes two parameters: the message as a String and the Session object representing the WebSocket connection.

Step 3: Deploy the endpoint to a server

The final step is to deploy the endpoint to a server. Tyrus Websocket can be deployed to any Java servlet container that supports the WebSocket protocol, such as GlassFish, Tomcat, or Jetty. Here’s an example deployment descriptor for GlassFish:

<web-app><display-name>My Web Application</display-name><context-param><param-name>org.glassfish.tyrus.servlet.websocket.endpoint.path</param-name><param-value>/echo</param-value></context-param><servlet><servlet-name>WebSocketServlet</servlet-name><servlet-class>org.glassfish.tyrus.servlet.TyrusServlet</servlet-class><init-param><param-name>org.glassfish.tyrus.servlet.ApplicationConfig</param-name><param-value>com.myapp.MyApplicationConfig</param-value></init-param><load-on-startup>1</load-on-startup></servlet><servlet-mapping><servlet-name>WebSocketServlet</servlet-name><url-pattern>/websocket/*</url-pattern></servlet-mapping></web-app>

This deployment descriptor maps the “/echo” URI to the EchoEndpoint class and configures the TyrusServlet to handle WebSocket connections. The MyApplicationConfig class is a custom application configuration that initializes the Tyrus Websocket server and registers the EchoEndpoint class.

Frequently Asked Questions (FAQ)

What is WebSocket?

WebSocket is a protocol that provides a two-way communication channel between a client and a server over the web. It enables real-time communication between web applications and is ideal for applications that require low latency and high throughput.

What is the Java WebSocket API?

The Java WebSocket API (JSR-356) is a standard API that provides a way to build WebSocket endpoints, client applications, and custom encoders/decoders on the Java platform. It is part of the Java EE 7 specification and is supported by many Java servlet containers, including GlassFish, Tomcat, and Jetty.
