There have been once again some changes in the client APIs which will require changing your code.

Package names

Several packages have been renamed to a more consistent convention under the prefix ‘org.granite.client.javafx’. Usually a simple ‘Optimize imports’ or search/replace in your IDE should be enough to do the necessary changes.

ChannelFactory API

The ChannelFactory API has been slighly changed to allow different channel types:

ChannelFactory channelFactory = new JMFChannelFactory();
channelFactory.start();
MessagingChannel channel = channelFactory.newMessagingChannel("long-polling",
    "longPollingChannel", "http://localhost:8080/gravityamf/amf.txt")
Consumer consumer = new Consumer(channel, "stocks", "europe");

For a websocket channel, you will also have to configure the transport:

ChannelFactory channelFactory = new JMFChannelFactory();
channelFactory.setMessagingTransport("websocket",
    new JettyWebSocketTransport());
channelFactory.start();
MessagingChannel channel = channelFactory.newMessagingChannel("websocket",
    "websocketChannel", "ws://localhost:8080/myapp/gravityamf/amf")
Consumer consumer = new Consumer(channel, "stocks", "europe");

For a UDP channel, assuming the granite-client-java-udp.jar library is present:

ChannelFactory channelFactory = new JMFChannelFactory();
channelFactory.start();
MessagingChannel channel = channelFactory.newMessagingChannel("udp",
    "udpChannel", "http://localhost:8080/myapp/gravityamf/amf.txt")
Consumer consumer = new Consumer(channel, "stocks", "europe");

Of course you can mix all these channels and get them from the same ChannelFactory.

Additionally you can use the ServerApp API if you don’t want to build the url yourself:

ServerApp serverApp = new ServerApp("/myapp", false, "localhost", 8080);
ChannelFactory channelFactory = new JMFChannelFactory();
channelFactory.start();
MessagingChannel lpChannel = channelFactory.newMessagingChannel("long-polling",
    "longPollingChannel", serverApp);
MessagingChannel wsChannel = channelFactory.newMessagingChannel("websocket",
    "websocketChannel", serverApp);
MessagingChannel udpChannel = channelFactory.newMessagingChannel("udp",
    "udpChannel", serverApp);

ServerSession API

The ServerSession API has also been updated.

You can now use the ServerSession to build Consumer and Producer objects:

ServerSession serverSession = new ServerSession("/myapp", "localhost", 8080);
serverSession.setMessagingTransport("websocket",
    new JettyWebSocketTransport());
serverSession.start();
Consumer lpConsumer = serverSession.getConsumer("long-polling",
    "stocks", "europe");
Consumer wsConsumer = serverSession.getConsumer("websocket",
    "stocks", "usa");
Consumer udpConsumer = serverSession.getConsumer("websocket",
    "stocks", "asia");
