COURSE SUMMARY This highly practical 3-day class on Comet and HTML 5 Web Sockets and Server-Sent Events (SSE) for Real-time Web applications was designed by Kaazing's Jonas Jacobi, CEO and co-founder of Kaazing corporation. This course will teach you how to create next generation real-time Web 2.0 solutions, using HTML 5 Web Sockets and SSE that work today.

Come and learn about Comet architecture, HTML 5 Web Sockets and SSE. With these new standards, the browser can now enjoy the first-class citizenry of network communications that has long been enjoyed by desktop applications. You will learn how to use the emerging standards to build scalable, mission critical real-time Web 2.0 applications such as:

* Trading System Clients
* Online Betting Applications
* Social Chat Solutions
* Performance Monitoring Applications
* RFID and GPS Tracking Applications
* Sports and News Broadcasting Applications

Upon completion of this course you will know how to create your own scalable, real-time Web applications with the latest HTML 5 standards-based technologies.

LEARN HOW TO:

* Master the fundamental technologies used to push information to Web clients
* Decide when and why to use Comet and its implications on your architecture
* Setup and configure an Enterprise Comet development environment and use Comet APIs
* Use client-side APIs to communicate directly with back-end systems such as JMS, XMPP, STOMP and SMTP
* Design, develop, debug and deploy testable and scalable real-time Java EE applications with Comet
* Address server-side scalability with Asynchronous Request Processing (ARP)
