Pense Imovies: Connecting real estate buyers and sellers using GlassFish

Pense Imoveis connects real estate buyer and seller in Brazil. This website is created by Grupo RBS, a multimedia communications based in the southern part of Brazil. After Guia da Semana, they picked GlassFish again to power this website because of the good performance and extremely fast startup and deployment time.

The deployment uses GlassFish 3.1.1 and Oracle database with RAC integration. Varnish is used for caching and mod_proxy_ajp for reverse proxying. The website is migrated from .NET to Spring on GlassFish. Even though this particular version of the application is using Spring but all future applications will be using Java EE 6.

With the upcoming FIFA world cup in 2014 and Olympics in 2016, now might be a good time to buy real estate in Brazil. And GlassFish will be happy to facilitate that!

Make sure to read full details in the questionnaire.

Jenzabar: Running a school or college using Java EE 6 and GlassFish

Jenzabar®, Inc., a leading provider of software, services and strategies for higher education, recently launched Jenzabar JX, a revolutionary new enterprise resource planning system built on open standards using Java EE 6 and GlassFish. Jenzabar JX gives institutions an extensible system with modern tools to successfully manage constituent relationships and meet the full spectrum of academic and administrative needs for today's technologically sophisticated students, faculty, and staff.

In developing a cost-effective solution to serve diverse institutions of higher education, Jenzabar needed an infrastructure for JX that was scalable and performed well in a wide variety of environments. In addition, with its legacy system, the company had experienced the pitfalls of supporting its own proprietary infrastructure, and resolved that JX would employ an open source infrastructure with standards compliance. Jenzabar identified the GlassFish application server and its supportive community as a solid base on which to build, enabling Jenzabar to focus its development energies on business logic for higher education. An added bonus, the embedded GlassFish server drives all integration testing within the JX product. Jenzabar customers are delighted with the direction of Jenzabar JX.

Mollom and GlassFish fight spam so you don't have to!

Mollom.com Mollom is a popular web service which helps websites keep spam and other unwanted content (such as website spam and profanity) off of their web site. While Dries Buytaert is the founder and leader of Drupal (a very popular open source content management system written in PHP), the backend for this service has always been written in Java and is now fully running using GlassFish 3.0.1.

This free service (with optional commercial offerings) has some impressive statistics with 30k+ active websites and more than 360 million spam messages caught since it started a few years ago. Around 700k spam messages are caught every day with an average rate of 60 requests per second.

In order to devote most of the work and energy into making the service even more effective (and less on maintaining the infrastructure), the backend was replaced with a Java EE 6 application (EJB Session beans, JAX-RS/Jersey, and JPA) with MySQL and Cassandra data stores, all of which is now powering 100% of the mollom instances.

You can read more about this in this detailed questionnaire by Johan Vos, the architect for the migration project. You can also listen to this episode of the GlassFish Podcast (#72).

Update: Johan now has a post up on his experience moving to Java EE 6 and GlassFish 3.0.1.
Update 2: don't have enough technical details? Read this new article published on HighScalability.com.
Update 3: mollom.com now has a blog post with the background for this project, the GlassFish choice and some forward-looking statements.

CDOVaR.net does online Risk and Pricing with OpenDS

CDO² is a a provider of innovative pricing and risk technologies. Hosted on Sun Network.com infrastructure, CDOVaR.net is a service provided by CDO² for structured credit pricing and risk, which allows financial institutions to transparently harness grid computing to manage their portfolios.

For user management, authentication and authorization, CDOVaR.net was looking for a Java based LDAP directory server, mainly to reduce the dependence on native code. After a trial period in the staging environment, replacing the existing LDAP product, OpenDS was adopted and allowed significant improvements in the systems deployment and the use of directory services.

As Dominic Cleal of CDO² writes: "We found OpenDS much simpler to deploy to a new environment, with far less dependencies and far easier to configure out of the box."

Make sure you read the full questionnaire for OpenDS adoption by CDOVaR.net for additional details on all of the above, and more.
