Please find below everything I think you've asked for, the real code is
somewhat distributed
across several different classes, but this should be pretty equivalent:
RECEIVER CODE
-------------
ConnectionOptions options = constructBasicConnectionOptions();
options.reconnectOptions()
.reconnectEnabled(true)
.useReconnectBackOff(true)
.reconnectDelay(5000)
.maxReconnectDelay(10240001)
.maxReconnectAttempts(12)
.warnAfterReconnectAttempts(1);
Client client= Client.create();
Connection connection = client.connect("host", 1234, options);
ReceiverOptions ro = new ReceiverOptions();
ro.autoAccept(false);
Receiver receiver = connection.openReceiver( "queue", ro )) {
Delivery delivery = receiver.tryReceive();
if( delivery != null ) {
Message<Object> message= delivery.message();
// Exception occurs here.
Object body= message.body();
}
SENDER CODE
-----------
final Client client = Client.create();
final ConnectionOptions options = new ConnectionOptions();
options.sslOptions().sslEnabled(true);
options.user("MY_USER");
options.password("MY_PASSWORD");
Connection connection = client.connect(serverHost, serverPort, options);
Sender sender = connection.openSender(address);
sender.send(Message.create((byte[])null));
FRAME TRACE
------------
