public abstract class WebSocketServlet
extends javax.servlet.http.HttpServlet
To use this servlet, you will be required to register your websockets with the WebSocketServletFactory
so that it can create your websockets under the
appropriate conditions.
The most basic implementation would be as follows.
package my.example; import org.eclipse.jetty.websocket.servlet.WebSocketServlet; import org.eclipse.jetty.websocket.servlet.WebSocketServletFactory; public class MyEchoServlet extends WebSocketServlet { @Override public void configure(WebSocketServletFactory factory) { // set a 10 second idle timeout factory.getPolicy().setIdleTimeout(10000); // register my socket factory.register(MyEchoSocket.class); } }Note: that only request that conforms to a "WebSocket: Upgrade" handshake request will trigger the
WebSocketServletFactory
handling of creating
WebSockets.
Configuration / Init-Parameters:
Note: If you use the @WebSocket
annotation, these configuration settings can be specified on a per WebSocket basis, vs a per Servlet
basis.
