Training Links - JRuby, MySQL, Memcached, Student Portal, Java with Passion
  Posted by pelegri in General

Sun offers quite a number of training courses, and some of them are even free. Some I noticed this week:

The Librarian, a painting

Trond highlights two very interesting free Webinars next week with top speakers (tip): "Highly scalable solutions with MySQL and Memcached" (Wed) and "Designing and Implementing Scalable Applications with Memcached and MySQL" (Thu).

Marina points to free Student Courses as part of the resources at the Student Portal.

Arun and Daniel mention Sang's latest course on Ruby and Rails. Sang's Java Passion site has many good online courses using the GlassFish Server, including JavaEE, Web Services and EJB.

Sun has many other courses, sometimes it's just a bit hard to find them. For example, the site for online and in classroom courses offered by Sun is http://www.sun.com/training and many of these are related to GlassFish, but a Search for "glassfish" will yield only a few of those.

We are working to fix that last problem, and I try to capture courses I know at GlassFishForBusiness, but what we really need is a full-time librarian... ideally a super one, like Conan the Librarian.

Image Processing in Rails using Java 2D API
  Posted by arungupta in Web.Next

Raisl Grayed Out

Using JRuby (instead of Ruby) to develop your Rails applications allow you to leverage the power of Java libraries in Rails applications. Java 2D API is one such API that provides support for advanced 2D graphics and imaging.

Jennifer has a good Writeup explaining image-filtering effects (negative, grayscale, brigthen, sharpen) using Java 2D API on an image.


The app runs using GlassFish v3 Gem but can be natively deployed on TP2 as well.

TP2 Docs provide a more comprehensive tutorial on how to get started with using Rails for the GlassFish v3 Application Server.

Online Billing in NZ Using GlassFish and JRuby
  Posted by pelegri in GlassFish

ALT DESCR

The web site for WorldxChange Communications NZ looks very good (they won the NZ Telecommunications Carrier of the Year 2007) and their Customer Bill View system is a JRuby Application running on GlassFish v2!

The application came from an strategic emphasis in improving the customer experience and was developed very quickly, that influenced the choice of technologies. Check out Chris' Adoption Story and check the Questionnaire.

The questionnaires for the Adoption Stories are always full of very interesting details; for example, WXC uses CentOS in production. Annecdotal data, but still, interesting.

Betting on JRuby and GlassFish
  Posted by arungupta in General

Heard on the blogosphere ...

Map of the Blogosphere

Teflon Ted's blog entry Rails Doesn't Scale is betting on JRuby and GlassFish. It says:

"Personally my money is on JRuby (and Glassfish) for the long haul; if you haven't checked out Glassfish yet, you're doing yourself a disservice!."


Have you checked out GlassFish v3 gem for JRuby ?

It is now hosted on RubyForge and can be easily installed using "gem install glassfish". Read more details here.

Updates of Popular GF Bundles - Liferay 4.4.1 and v3 Ruby GEM
  Posted by pelegri in GlassFish

ALT DESCR

Updates to two popular GlassFish-based bundles. The GF v3 Gem now has a a Bug Fix Update (v0.1.1); Pramod also includes plans for v0.1.2. The second is Liferay 4.4.1, also mostly bug fixes.

I enjoy data mining, so I poked around a bit at the download stats. The GF-based Liferay bundles have been increasing, from 5.4% in 4.3.0 to 15.1% in 4.4.1. And, since JBoss Portal 2.6.4 released the exact same day as Liferay 4.4.1, a comparison between the two was easy: 3778 for Liferay and 1053 for JBoss Portal.

GlassFish v3 Ruby Gem - Now at RubyForge
  Posted by pelegri in Web.Next

ALT DESCR

The GlassFish (v3) Gem (older TA entries) has moved and it now lives at RubyForge.

Arun gives Details on the Gem and the Move and also, separately, reports on interest on the Gem and other JRuby at the Acts_as_Conference 2008 ([Day 1] and [Day 2]).

The Gem is a very interesting direction; not yet ready for production, but we are trying to move as quickly as we can. BTW, most of the GFv3 development traffic has succesfully moved to the DEV alias, and you can trak it there.

Hudson - pretty simple and works like a charm
  Posted by arungupta in General

JRuby CI Hudson Test Results

"Great tool for your continuous integration needs", "pretty simple and works like a charm" and "truly a sweet tool" are phrases commonly associated with Hudson. This time they are coming from JRuby / Ruby community.

This post describes how to setup Hudson for running your Ruby and JRuby tests. The post describes a gem CI:Reporter that formats the test results in XML format that can then be easily consumed by Hudson.

And if you want to show your support for Hudson, go visit the CafePress Store.
