Zero Downtime of JavaEE applications and Home Automation with Java and Arduino

Zero Downtime of JavaEE applications and Home Automation with Java and Arduino

Please note this is an LJC event. SkillsMatter are hosting this event and are handling the attendance - it is essential that you confirm your place at this link:

JavaEE Applications in Production: Tips and Tricks to achieve zero downtime (45 minute talk) - details below

Jhome: Using JavaEE and open-source hardware to automatize your house (45 minute talk) - details below

JavaEE Applications in Production: Tips and Tricks to achieve zero downtime will be presented by Fabiane Nardon - If you think your work is finished when your application is in production, you're wrong. That is when the most stressful part of the application lifecycle will begin. There is little tolerance for errors and downtime can destroy your business. Achieving zero downtime in a JavaEE application is not easy, but in this presentation you'll learn several tools, tips and tricks to get there.

In a demo only presentation, we'll show how to monitor your application using the container resources and open source tools, how to continuously deploy your application with zero downtime, how to find bottlenecks and memory leaks that happen only in the production environment, and more!

The presentation will include live coding and live demos. We'll start from a JavaEE application and add tools and techniques to it to achieve zero downtime.

 The presentation is specially targeted to JavaEE developers. Both junior and experienced developers should benefit from it.

Jhome: Using JavaEE and open-source hardware to automatize your house will be presented by Vinicius Senger and Yara Senger.

During this presentation we will be showing how you can use Java EE and open-source hardware, like Arduino, to automatize your house. Using jHome, a complete Java EE 6 API for home automation, you can control lamps, wall sockets, electric gates and doors using Web App and Twitter.

We will not present a product! It's a complete solution that you can do it yourself with open-source hardware and software and you will have a lot of fun with Java EE 6 with this different usage context!

This talk will cover:

Introduction to Home Automation and open-source hardware
Project jHome
Cool demos:
Servlets controlling lamps
Controllling RGB with jQuery
Scheduling coffee-machine with EJB's
Using sounds and FFT(fast fourier transforming) to control your house

This is a basic talk and useful for any developer professional level.

    Really excellent night, both of the main presentations were interesting and relevant, and extremely well presented. Nice to meet the SouJava guys (again), the LJC has a lot in common with the Brazillian JUG. It was great to chat to new people as well.

    in my opinion the Zero Download Time part was too long while the Arduino presentation was great.
