-== Websocket (WS) IO
-
-APEX supports the Websockets as input as well as output.
-WS IO is supported by the APEX Websocket plugin.
-This carrier technology does only support uni-directional communication.
-APEX will not send events to a Websocket input and any event sent to a Websocket output will result in an error log.
-
-The input can be configured as client (APEX connects to an existing Websocket server) or server (APEX starts a Websocket server).
-The same applies to the output.
-Input and output can both use a client or a server configuration, or separate configurations (input as client and output as server, input as server and output as client).
-Each configuration should use its own dedicated port to avoid any communication loops.
-The configuration of a Websocket client is the same for input and output.
-The configuration of a Websocket server is the same for input and output.
-
-
-=== Websocket Client
-
-APEX will connect to a given Websocket server.
-As input, it will receive events from the server but not send any events.
-As output, it will send events to the server and any event received from the server will result in an error log.

-== BCP: Websocket Configuration
-
-The probably best is to configure APEX for Websocket servers for input (ingress, consume) and output (egress, produce) interfaces.
-This means that APEX will start Websocket servers on named ports and wait for clients to connect.
-Advantage: once APEX is running all connectivity infrastructure is running as well.
-Consequence: if APEX is not running, everyone else is in the dark, too.
-
-The best protocol to be used is JSON string.
-Each event on any interface is then a string with a JSON encoding.
-JSON string is a little bit slower than byte code, but we doubt that this will be noticeable.
-A further advantage of JSON strings over Websockets with APEX starting the servers: it is very easy to connect web browsers to such a system.
-Simple connect the web browser to the APEX sockets and send/read JSON strings.
-
-Once APEX is started you simply connect Websocket clients to it, and send/receive event.
-When APEX is terminated, the Websocket servers go down, and the clients will be disconnected.
-APEX does not (yet) support auto-client reconnect nor WAMP, so clients might need to be restarted or reconnected manually after an APEX boot.

-== Websocket Example Code for Websocket clients (FOSS)
-
-There are a lot of implementations and examples available on Github for Websocket clients.
-If one is using Java EE 7, then one can also use the native Websocket implementation.
-Good examples for clients using simply Java SE are here:
-
-- link:https://github.com/TooTallNate/Java-WebSocket[Websocket implementation]
-- link:https://github.com/TooTallNate/Java-WebSocket/blob/master/src/main/example/ChatClient.java[Websocket sending client example, using AWT]
-- link:https://github.com/TooTallNate/Java-WebSocket/blob/master/src/main/example/ExampleClient.java[Websocket receiving client example (simple echo client)]
-
-For Java EE, the native Websocket API is explained here:

-== Websockets
-
-Websocket is a protocol to run sockets of HTTP.
-Since it in essence a socket, the connection is realized between a server (waiting for connections) and a client (connecting to a server).
-Server/client separation is only important for connection establishment, once connected, everyone can send/receive on the same socket (as any standard socket would allow).
-
-Standard Websocket implementations are simple, no publish/subscribe and no special event handling.
-Most servers simply send all incoming messages to all connections.
-There is a PubSub definition on top of Websocket called link:http://wamp-proto.org/[WAMP].
-APEX does not support WAMP at the moment.

-== Websocket in Java
-
-In Java, link:http://www.oracle.com/technetwork/articles/java/jsr356-1937161.html[JSR 356] defines the standard Websocket API.
-This JSR is part of Jave EE 7 standard.
-For Java SE, several implementations exist in open source.
-Since Websockets are a stable standard and simple, most implementations are stable and ready to use.
-A lot of products support Websockets, like Spring, JBoss, Netty, … there are also Kafka extensions for Websockets.
