WebSocket is coming with HTML5, and building rich real-time event-driven Web applications will be the future. GlassFish, as of Release 3.1.2, now supports WebSocket, so now is an ideal time to learn this new technology. This tutorial builds a WebSocket Web application hosted on GlassFish that can deliver stock updates from a data grid directly to the Web browser in real time.

How many times have you wanted to start a new project in Java EE but struggled to put all the pieces together? Has the Maven archetype syntax left you scratching your head? Everyone else is talking about Rails, Grails, and Roo, and you are left thinking, “I wish it were that easy for me.” Well, there is good news, as this session illustrates: you don’t have to leave Java EE just to find a developer tool that makes starting out simple.

his video demos how to quickly get to a fully agile project setup with continuous deployment. Everything is in the cloud – GIT repo, Jenkins, MongoDB and the app server. The system deploys automatically with every successful commit. The app itself is minimal, but does have a simple web interface and a database. The idea is that once you get this “walking skeleton” type app running in the cloud with continuous deployment, you can get user feedback early and often, and evolve more quickly.

This video demonstrates the power of CSS preprocessors like Sass, Less, or Stylus.  It explains why these are a game changer for front-end development.
