Examples with Session javax.websocket.Session used on opensource projects

Example 1 with Session

use of javax.websocket.Session in project tomcat by apache.

the class TestWebSocketFrameClient method testConnectToServerEndpoint.

@Test
public void testConnectToServerEndpoint() throws Exception {
    Tomcat tomcat = getTomcatInstance();
    // No file system docBase required
    Context ctx = tomcat.addContext("", null);
    ctx.addApplicationListener(TesterFirehoseServer.Config.class.getName());
    Tomcat.addServlet(ctx, "default", new DefaultServlet());
    ctx.addServletMappingDecoded("/", "default");
    tomcat.start();
    WebSocketContainer wsContainer = ContainerProvider.getWebSocketContainer();
    ClientEndpointConfig clientEndpointConfig = ClientEndpointConfig.Builder.create().build();
    Session wsSession = wsContainer.connectToServer(TesterProgrammaticEndpoint.class, clientEndpointConfig, new URI("ws://localhost:" + getPort() + TesterFirehoseServer.Config.PATH));

    BasicText handler = new BasicText(latch);
    wsSession.addMessageHandler(handler);
    wsSession.getBasicRemote().sendText("Hello");
    System.out.println("Sent Hello message, waiting for data");
    // Ignore the latch result as the message count test below will tell us
    // if the right number of messages arrived
    handler.getLatch().await(TesterFirehoseServer.WAIT_TIME_MILLIS, TimeUnit.MILLISECONDS);
