JotBot: Time-tracking application using JRuby, Ramaze, and GlassFish

GetJotBot.com 
JotBot is a cross-platform desktop-based time tracking application. It is written using JRuby, Swing, Monekybars, and Ramaze. The application is deployed on GlassFish on a VPS hosted on eApps.

A key part of the evaluation critera were better deployment and management and the options offered by hosting companies. The use of GlassFish enabled the JotBot team to focus more on development effort and less on sysadmin work and offered a solution that has been working with no trouble for a few months now

Sequel is used as the ORM for talking to MySQL and H2 databases and NetBeans was used for designing the screens. Here is a thought on the JRuby and GlassFish community:

There's a pioneer spirit, and that makes it more fun for everyone.

The detailed GlassFish questionnaire provide additional details on all of the above.

GlassFish v2 and JRuby powering WorldxChange Communications NZ's online billing system

Logo for WorldxChange Communications

WorldxChange Communications NZ have just won the NZ Telecommunications Carrier of the Year 2007. While looking at their competitors they decided to refocus their efforts towards an online system to actively view their call records and past history information for our customers verses making sure they grow their customer base, see Grant McLaren's comments from WorldxChange Communications NZ here.

The project started out as a Proof Of Concept, 8 weeks later, it went live, see ViewBill Portal Link. The ViewBill Portal Link project is based on JRuby, GlassFish v2 and NetBeans 6.1. One of the reasons they chose NetBeans, GlassFish and JRuby was, as Grant McLaren puts it, "I came across Glassfish. From my perspective, the main advantage was that I could deploy my JRuby project war file directly to GlassFish, allowing me to develop and test our online ViewBill portal using a production grade, scalable web server." Since then, WorldxChange Communications NZ have since started using GlassFish v3 with the JRuby gem for testing of new code features before going in to production.

To read through all of WorldxChange Communications NZ's reasons why they chose GlassFish and Jruby, see their full questionnaire here. Here's how WorldxChange Communications NZ summarizes their reasons for using GlassFish and JRuby; Grant McLaren writes, "I do not believe that I could have developed this project any faster using different toolsets or technologies and have been massively impressed with the combination of Glassfish and JRuby." and "I like the fact that it is a production grade web server that is reliable, scalable and packed full of features. As we traditionally use Apache web servers, Glassfish fulfilled the requirements of this project and it was easily incorporated into our existing network. Not too mention being backed by the reputable company Sun, it made Glassfish the perfect choice."
