jHome Testimonial at GlassFish Community Event, JavaOne 2012


jHome Automation, a Duke Choice Award 2011 winner, is a complete platform for home automation that allows you to control your home via internet, phone, and television. It also allows you to extend to devices that can be built yourself or bought as pre-assembled kits.

Vinicius Senger, founder of GlobalCode, the company behind the platform, presented at the GlassFish Community Event at JavaOne 2012 and shared how they used Java EE for building the infrastructure. They rely upon EJBs and REST APIs to provide home automation.

They like fast deployment times, CLI interface, rapid pace of evolution, and lightweight container. This is a "dream application server" for them which is very reliable in production. Other than jHome, GlobalCode uses GlassFish for consulting and training as well. They also see the trend in Brazil where customers are moving from JBoss -> GlassFish.

Dont' forget to watch the complete video for a fun demo of the project. I particularly like the coffee scheduler using EJBs. What is your favorite ?

Parleys Testimonial at GlassFish Community Event, JavaOne 2012


Parleys.com is an e-learning platform that provide a unique experience of online and offline viewing presentations, with integrated movies and chaptering, from the top notch developer conferences and about 40 JUGs all around the world.

Stephan Janssen (the Devoxx man and Parleys webmaster) presented at the GlassFish Community Event at JavaOne 2012 and shared why they moved from Tomcat to GlassFish. The move paid off as GlassFish was able to handle 2000 concurrent users very easily. Now they are also running Devoxx CFP and registration on this updated infrastructure. The GlassFish clustering, the asadmin CLI, application versioning, and JMS implementation are some of the features that made them a happy user.

Recently they migrated their application from Spring to Java EE 6. This allows them to stay away from getting locked into a proprietary framework and also avoid 40MB WAR file deployments. Stateless application, JAX-RS, MongoDB, and Elastic Search is their magical forumla for success there.

More details about their infrastructure is available here.

Parleys.com: Feedback from GlassFish Community Event at JavaOne 2011


Parleys.com provide a unique experience of online and offline viewing presentations, with integrated movies and chaptering, from the top notch developer conferences and JUGs all around the world. The infrastructure has recently started using GlassFish and is discussed in detail here.

Stephan Janssen (the Devoxx man and Parleys webmaster) presented at the GlassFish Community Event at JavaOne 2011 and shared why they moved from Tomcat to GlassFish. The GlassFish clustering, the asadmin CLI, application versioning, and JMS implementation are some of the features that made them a happy user.

LodgON: Feedback from GlassFish Community Event at JavaOne 2011


LodgON focuses on Java software for enabling communities. Their success story of DaliCMS (now DaliCore) was one of the first ones to be published on this blog. And their stories of iVOX, fun around Belgian and Dutch elections, and recently Mollom is a good proof that they are one of the first adopters of GlassFish and continue to use it for all these years.

Johan Vos, CTO of LodgON, presented at the GlassFish Community Event at JavaOne 2011 and shared what they love about GlassFish. The grizzly kernel performance which can handle 15,000 requests/second, Jersey client for communicating with RESTful Web services, horizontal scalability, and the open source nature are some factors.

The slides below provide more details:

Parleys.com goes GlassFish

If you're a Java developer, you owe it to yourself to know and use Parleys.com.

With over 1000 technical presentations from the best developer conferences and JUG meetings around the world, this is a unique resource for technical content. The user experience is probably also one of the best in the market with chaptering, integrated movie and demos, offline mode, integrated social media and more.

What you may not know is how a GlassFish 3.1.1 cluster replaced a Tomcat instance to reliably power the service. Stephan Janssen (BeJUG leader, Devoxx guru and Parleys master) took the GlassFish Questionnaire and shares his experience.

You'll find that Parleys.com uses the web container (with virtual hosting), GlassFish application versioning (doc), clustered MQ brokers and other product features and Java EE APIs. The application also uses a good number of frameworks such as Spring, Hibernate, Wicket, BlazeDS among others. Future plans include some refactoring to use more Java EE 6 technologies (namely EJBs).

Micello Runs on GlassFish and MySQL

Micello provides maps for indoor locations like shopping malls, department stores, big-box stores, office buildings and the like.  For instance, they have maps for the Stanford Shopping Center and my local IKEA.  They currently have clients for the iPod, the iPad and the Android, and their server-side technology runs on GlassFish and MySQL.

Check out Arun's interview of Prakash Narayan, Micello's CTO, during Oracle OpenWorld a couple of weeks ago.

Belgian and Dutch elections - GlassFish swims to the cloud

Deployment topology Take some bleeding edge version of GlassFish 3, use a full Java EE 6 architecture to write a web application and deploy everything on Amazon's EC2 service. The result is what Johan Vos describes in this detailed blog entry. This production deployment includes three different traffic-heavy web sites for people to find which of the candidates to the Dutch and Belgian parliament elections is their "closest match".

In this deployment topology, requests are handled directly by the grizzly layer of GlassFish with no extra front-end HTTP layer and shows great performance and scalability. The application itself is fully built using Java EE 6 and Johan discusses the EJB and JAX-RS architectural choices implemented in the application as well as HTTP listener and thread pool configurations, claiming that "(GlassFish offers) flexible and transparent tuning".

Johan works for LodgON, the makers of the Dali suite of products and their partner IvoxTools is reponsible for the deployment projects. Check out also Episode #37 of the GlassFish Podcast, an interview with Johan about Java EE and GlassFish from last December.

Xerox Global Services documents its production use of GlassFish

Xerox Global Services, one of three main business units within Xerox, offers outsourcing and consulting services and is our latest production story for GlassFish. It has almost been a year since the company has decided to deploy GlassFish in France as their Main Java application server on Sun Solaris systems. Applications using this infrastructure range from internal tracking systems to customer document management, and document exchanges between Xerox and its customers.

The set of technologies running on top of GlassFish include a fairly typical struts, hibernate, spring combination. These applications used to run on top of Tomcat. There are now more than 30 applications deployed in a total of 5 clusters and all GlassFish instances are hosted in Solaris 10 containers. As with every other story, GlassFish is used both for development and deployment. Check out the detailed questionnaire for more details.

4HomeMedia uses the GlassFish Comet for a better digital home experience

4HomeMedia

4HomeMedia is a startup based in Sunnyvale, CA. They won the “Best of Innovations” award at the recent 2007 CES conference for their in-home network service. Their product allows remote-control and remote-monitoring of any networked device or service in the home.

Their portal services is a secure doorway into the consumer's home. When it goes into production this spring it'll be making the most out of GlassFish's Comet support to enable server-initiated communications for a high number of always-on HTTPs connections. Control of your house equipment will then be in your hands from wherever you are.

The 4HomeMedia development team has been a great contributor to the GlassFish community providing extremely valuable feedback to the Grizzly/Comet lead Jeanfrancois Arcand.

Make sure you read the detailed questionnaire responses and learn about the ambitious and exciting projected number of concurrent sessions together with the rest of the GlassFish experience..
