4. Create a simple
WebSocket
application

5. Using WebSockets in a Java EE Environment to
Improve Web Application Development
 Programming model for the Java EE environment
 WebSocket API
•Endpoint configuration
•Session open/close
•Message read/write
•Error handling
•Annotations
 WebSocket network protocol
•Optimized Data format

6. WebSocket connection
Handshake:
•Client initiates connection
•Server responds (accepts the upgrade)
Once the WebSocket is established
•both sides notified that socket is open
•either side can send messages at any time
•either side can close the socket

7. WebSockets API
Programmatic or annotation-based approach
Client and Server Endpoints
•Have a lifecycle
–onOpen
–onClose
–onError
•Communicate using Messages
–onMessage
–send
•Use sessions
Encoders and Decoders deal with data formatting
•Messages Java Objects

What is WebRTC?
Why is WebRTC so disruptive?
Eliminates complexity of delivering codecs and streaming protocols.
Closely aligned with HTML 5.
Enables real-time data communications in addition to voice and video.
Strong industry support.
Enables contextual communications!
WebRTC offers web application developers the
ability to write rich, realtime multimedia applications
on the web, without requiring plugins, downloads or
installs. (source www.webrtc.org)
WebRTC does not define the signaling plane. It only defines a model for sending
and receiving media and a set of protocols for traversing firewalls.

13. rtcomm.js – JavaScript client for Rtcomm
• Raw JavaScript library for Real-Time Communications
• WebRTC + Signaling + Presence = rtcomm.js
• Supports chat, queues, and presence
• Includes sample video chat application
• Foundation for advanced app development
bower install rtcomm
https://github.com/WASdev/lib.rtcomm.clientjs

16. lib.angular-rtcomm – Rtcomm for AngularJS
• AngularJS module
• UI elements for rapid client app integration
• Ready for modern web application development
https://github.com/WASdev/lib.angular-rtcomm
bower install angular-rtcomm

18. Create a Third-
Party Calling
Application

19. Rtcomm and Node-RED
Node-RED:
• A visual tool for wiring the Internet of Things like:
• MQTT enabled devices, MongoDB, Twitter, and much more!
Rtcomm Node-RED Nodes
• Third-Party Call Control
• Event monitoring
https://github.com/WASdev/lib.rtcomm.node
https://github.com/WASdev/lib.rtcomm.node-red
npm install node-red-contrib-rtcomm
npm install rtcomm
