Hi,
I am Ashitraj More, developer from India
I have created a free video tutorial on Java WebSocket API.
http://programming-simplified.com/java_websocket_api_training.html
The entire video tutorial is around 1 and 1/2 hours.
Salient features:
* Complete and comprehensive( covers most of the aspects of the specs).
* End to end examples(explains everything right from java code
to aspects of javascript and jquery).
* The tutorial doesn't shy away from wholeheartedly using related
technologies.( New HTML 5 semantic tags, drag and drop, jquery ).
* Covers the theory about WebSockets.
* Uses Tyrus on Glassfish 4.
Coming up is a tutorial on JSON API.
